EXECUTIVE SUMMARY

 

The Soque River is the northeastern-most tributary of the Chattahoochee River and has a number of beneficial uses both locally and regionally within the State.  The river serves as the drinking water source for the City of Clarkesville and tributaries to the river provide water for other localities in Habersham County.  Additionally, the river supplies an estimated 1/6 of the inflow to Lake Lanier, the major drinking water reservoir for the City of Atlanta.  The Soque is also renowned for the recreational opportunities it provides; primarily fishing.  The watershed covers approximately 160 square miles and rests wholly within Habersham County, thus presenting a unique opportunity for watershed protection and management while avoiding jurisdictional conflicts.  

 

As in much of Georgia, rapid population growth in Habersham County is expected to increase the demand for water supplies while adding stressors to aquatic systems.  The Georgia Department of Community Affairs documented a 30% increase in the population of Habersham County between 1990 and 2000 (GADCA 2006).  Growth estimates by the State Office of Planning and Budget forecast an additional 37% increase in population in the County between 2000 and 2015 (GAOPB 2005).  These figures together represent a near doubling of the population of the county in a 25 year span.

 

The Soque River Watershed Partnership (the Partnership) was formed to take advantage of the opportunity for local protection of water resources and in response to water quality concerns and the anticipated impacts of rapid growth in the watershed.  The Partnership is comprised of numerous local and state agencies and organizations and is guided by a Steering Committee of stakeholders and a Technical Advisory Committee of scientific and resource professionals.  Partnership formation was driven by a concern for the sustainability of local water supplies and the identification of impaired waters in the watershed.

 

Recent surveys by the Georgia Environmental Protection Division (GAEPD) and the United States Environmental Protection Agency (USEPA) identified stream segments in the watershed that do not meet state water quality standards.  These stream segments have subsequently been placed on the State’s 303(d) list of impaired waters.  Specifically, two segments of the Soque River (totaling 35 miles) are not supporting designated uses due to violations of the fecal coliform bacteria standard from unspecified non-point source (NPS) pollution.  Additionally, two segments of Hazel Creek (totaling nine miles), a tributary to the Soque, are not supporting designated uses due to NPS sediment impacts on instream habitat and biota (GAEPD 2008). 

 

In recognition of these water quality impairments from NPS pollution, the Partnership applied for and received CWA §319(h) funding from the USEPA and administered through GAEPD.  The funding was to complete a comprehensive watershed assessment to document current biological, chemical, and physical conditions in the watershed.  The data was then used to draft this watershed protection plan for use by citizens and municipalities to make informed decisions about the future use and protection of water resources in the watershed. 



INTRODUCTION

 

The Soque River Watershed comprises 160 square miles, or 57% of the land area of Habersham County (Figure 1).  The watershed is unique for its size in that it lies wholly within the boundaries of a single county.  This presents a rare opportunity for local resource protection while avoiding jurisdictional conflicts. 

 

The headwaters of the river flow from National Forest lands off of Tray Mountain and run together in the Blue Ridge Physiographic province (Level IV ecoregion 66d – Southern Crystalline Ridges and Mountains) to form the main-stem of the Soque.  The river continues down through the Piedmont (Level IV ecoregion 45a – Southern Inner Piedmont) to the confluence with the Chattahoochee River.  The Soque is the northeastern most tributary to the Upper Chattahoochee River (8-digit HUC 03130001).  

Figure 1.  Location of Habersham County and the Soque River Watershed

 

 

 

The river serves as the water supply for the City of Clarkesville.  Additionally, Hazel Creek and Camp Creek, tributaries to the Soque, supply water for the City of Cornelia.  Other localities in Habersham County, the cities of Demorest and Baldwin, obtain drinking water from the Chattahoochee River below the confluence with the Soque.  Municipal water supplies for Mount Airy and Alto come from groundwater wells within the watershed.  Nearly every Habersham County resident who drinks water from a public supply drinks at least some water from the Soque River.  The river is also important to the local economy.  The two biggest sources of revenue in the county are agriculture and tourism – both highly dependant on the river and watershed, both for resource availability (agriculture) and aesthetic beauty (tourism).  The Soque is also nationally renowned as a trophy trout stream, a status that requires high quality, clean water.

 

In response to problems already identified in several stream segments and threats from rapid development and other sources, a broad coalition of groups, known as the Soque River Watershed Partnership, joined together to perform a watershed-wide assessment of surface water quality. This assessment has was funded by a 319(h) grant awarded to the City of Clarkesville, which began in 2004 and concluded in March, 2008. The purpose of that first-round 319 grant-funded project was to gather data needed to complete a Watershed Protection Plan, through which the Partnership can address the highest priority threats to water quality and watershed integrity. 

 

Measures to eliminate pollution sources that have contributed to the designation of four stream segments in the watershed as “Impaired Waters” by the State of Georgia and the U.S. EPA will be the highest priorities in this protection plan (Table 1).  A map showing the 303(d) listed stream segments in red is also included in Figure 3.  The goal of the plan is to implement management strategies to improve water quality in the listed stream segments to the point that they are removed from the list of impaired waters.  Other streams and sub-watershed areas will also be targeted as high priorities for corrective and protective actions, due to findings of significant water quality problems in those areas.  Further, the corrective actions proposed here will carry out portions of the pertinent Total Maximum Daily Load (TMDL) implementation plans (State of Georgia, Recommended Tier 2 TMDL Implementation Plan: Hazel Creek; Recommended Tier 2 TMDL Implementation Plan: Soque River, Georgia Mountains Regional Development Center, 2004).

All watershed protection and management strategies detailed in this plan should be evaluated and adapted to best meet local needs and ensure progress towards the attainment of water quality standards.  Furthermore, action should not be limited to the contents of this plan.  Other alternatives should be considered as additional information or resources become available.

 

           

 

 

WATERSHED CONDITIONS

 

For the purpose of this plan, the Soque River Watershed has been further divided into tributary sub-watersheds (Figure 2).  This division will enhance the identification, prioritization, and implementation of protection efforts and corrective actions.  A summary of landcover for sub-watersheds (and for the entire Soque River Watershed) used in this plan is included in Table 2.  Subwatersheds will be listed in all tables in the order in which they enter the main-stem of the river from north to south.

Physical, chemical, and biological data collected during the watershed assessment indicate significant relationships among those variables and landcover (Figure 4) in the watershed.  For example, high levels of urbanization are strongly correlated with increasing fine sediment in streams and fewer numbers and types of benthic macroinvertebrates that are intolerant of NPS pollution.  Conversely, heavily forested areas had less instream sediment and a greater diversity and abundance of stream organisms intolerant of pollution (SRWP, 2008).  It is noteworthy that the landcover data used in the assessment is somewhat dated (NARSAL, 2001).  It is expected that even more forested and agriculture lands have been converted to developed areas between then and now. 

 

The assessment identified watershed areas and stream segments both in need of continued protection and corrective action.  Primary sources of bacteria identified included livestock, humans, and urban runoff (domestic pets and humans).  Sediment inputs were primarily attributed to land disturbing activities (improperly managed construction sites), streambank erosion, and dirt roads.  NPS management measures will be targeted towards reducing pollutant inputs from these sources.

POLLUTANT SOURCES AND CAUSES

 

Source assessments for this plan focus on fecal coliform bacteria and sediment, the causes of the failure to meet designated uses and water quality standards.  Potential pollutant sources were considered and evaluated using data collected during the watershed assessment.  Potential sources of bacteria include wildlife, livestock, humans, pets, broken sewer lines and overflows due to rain events, point source discharges (Figure 6), and failing septic systems.  Potential sources of sediment include all land disturbing activities, streambank erosion, and dirt roads. 

 

Bacterial samples were taken quarterly at 76 sites in the watershed over a period of two years, and E. Coli was used as an indicator organism indicative of the level of bacterial pollution (Table 3).  Tributaries draining to the upstream listed Soque River reach (29 mile segment) include the Headwaters, Raper Creek, Shoal Creek, and Deep Creek.  The three remaining major tributaries drain to the downstream listed reach of the Soque (6 mile segment).  Data were evaluated using a geometric mean for comparison with USEPA recommended levels for E. Coli (126 colony forming units / 100 mL of water).  Bacterial load reductions were estimated for each sample point in the subwatershed under consideration and loads were modeled for comparison with actual data.  Corrective actions to reduce bacterial inputs will be prioritized using these data.

Sediment data (suspended sediment concentration) were collected as baseflow and stormflow throughout the subwatersheds and on the mainstem of the Soque River.  Although Hazel Creek is the only stream in the watershed listed for sediment impacts on biota, excessive erosion and sedimentation is a concern throughout the watershed.  Sediment loads generally increased from north (more forested) to south (more disturbed) in the watershed (Table 6).  Excess sediment has many detrimental effects on aquatic life and increases the cost to treat drinking water.  Corrective actions will focus on lands that drain to Hazel Creek, but will also be undertaken where sediment inputs are identified elsewhere.  It is understood that education will be necessary for property owners and land disturbers to effectively reduce sediment inputs over time.

POLLUTANT LOAD REDUCTIONS

 

Pollutant load reduction estimates needed to meet water quality standards for fecal coliform bacteria and suspended sediment were modeled, calculated and compared with field collected data to refine prioritization of corrective actions.  Necessary load reductions will be discussed as pollutant specific.  However, it is anticipated that management and protection strategies will address both bacteria and sediment in many instances.

 

BACTERIA

 

Fecal coliform bacteria data for the entire Soque River Watershed were modeled using the Bacteria Source Load Calculator (Virginia Tech, 2007), which requires user defined inputs for potential pollutant sources.  These input data were gathered from the Georgia Department of Natural Resources Wildlife Resources Division (wildlife), Georgia Cooperative Extension (livestock), HHHHHHabersham County Health Department (septic systems), and the Georgia Department of Community Affairs (human population).  Fecal coliform production loadings from various sources are found in Table 4.  It is assumed that the agricultural and wildlife contributions are higher in more forested and agricultural areas of the watershed and that urban contributions (humans and pets) are more significant in rapidly developing areas with more impervious surfaces.

Model results do provide a starting point to prioritize management decisions.  In this case, more specific watershed data are available from the watershed assessment.  To further refine the available control measures and corrective action locations, field collected data were analyzed by sub-watershed.  The results of needed load reductions percentages, based on bacteriological sample data, are included in Table 5.

SEDIMENT

 

Sediment load reductions were derived using data from a recent United States Department of Agriculture Study (USDA, 2006).  In that study, the Chattahoochee River at Cornelia, below the confluence with the Soque River, was estimated to yield 147.6 tons/year/mi2.  Using that value for the Soque River Watershed, and accounting for landcover variables, it is possible to estimate the contribution of the subwatersheds in this study to the overall load.  A breakdown of suspended sediment yield and load estimates by subwatershed is included in Table 6.  According to the Hazel Creek TMDL Implementation Plan, the sediment load in that subwatershed needs to be reduced by 60% to meet unimpaired standards for habitat and biota (GMRDC, 2004a).  Due to existing and potential future landcover variables, it is anticipated that some subwatersheds will not require less attention (Headwaters, Raper, and Shoal) while others will need extensive management and protection measures (Hazel and Yellowbank, particularly) to reduce sediment loads to acceptable levels.

NPS MANAGEMENT MEASURES

 

Achievement of the estimated load reductions needed to attain water quality standards and promote the integrity of aquatic life will require multiple concurrent resource protection and management strategies.  Specific projects will be considered on a case by case basis among the subwatersheds with the highest priority needs.  The goal of this plan is to implement measures to greatly reduce or eliminate pollutant sources resulting in progress towards attainment of desired water quality standards.  Many of these best management practices (BMPs) will be designed, installed, and maintained as part of a system of measures to control pollutants – not as stand alone practices.  As priority sites are identified for protection and corrective action, site-specific conditions will be evaluated and recommendations made to best control pollutants by cost-effective measures in that particular situation. 

 

A number of specific sites were identified during the watershed assessment that require attention to reduce pollutant loads (Figures 6 and 7).  As part of the upcoming Clean Water Act § 319(h) implementation grant, entitled Soque River Watershed Protection Plan Implementation, the Partnership will begin addressing these sites and adapt strategies as new data and information become available to achieve desired goals.  Specific project activities at these sites over the next three year grant period are included below.

 

Bacterial Pollution Control – Through our monitoring program, we have measured high bacterial levels in each of five sub-watersheds within the Soque watershed. These include: Beaverdam Creek, Deep Creek, Shoal Creek, Yellowbank Creek, and Hazel Creek. The Deep Creek and Shoal Creek sub-watersheds feed the Soque River in the 29 mile segment listed for fecal coliform bacteria pollution. The other three are tributaries to the River in the downstream listed 6 mile segment. By taking bacterial samples at from 8 to 17 sites within each sub-watershed, we have narrowed down the potential areas of impact on stream quality from pathogens in each area. Upstream of each site with consistently high bacterial counts, we have begun identifying specific causes for the contamination. In many of these cases we know that cattle in streams and crossings are certainly contributing to water quality problems. We also are seeking to identify failing residential drain fields and other possible sources of fecal coliform bacteria in each targeted watershed area. We will continue to identify even more specific sites likely contributing these types of pollution. We plan to identify a number of sites in each of these sub-watersheds where we can work with landowners to do one of two measures. For farms, we will install fencing and alternative water sources to get cattle out of streams and improve or eliminate stream crossings. Fencing will also allow for the reestablishment of stream buffers to filter pollutants from overland runoff.  For residential sites with failing or problem drain fields, we will make repairs or replace system components to eliminate leakage to surface waters. 

 

The upstream listed segment of the Soque River is drained by 4 major subwatersheds, two of which contribute relatively little to total bacterial loading (Headwaters and Raper Creek).  Therefore, we will concentrate our efforts for the upstream segment in the two remaining subwatersheds, Shoal Creek and Deep Cree.  In the Shoal Creek sub-watershed, we have already identified a farm where we will work with owners to provide fencing and alternative water supplies.  We have also identified two more with whom we intend to work on similar projects. As the Shoal Creek drainage is relatively small and contains a very large percentage of national forest land, we believe these projects could eliminate the bacterial problem identified there, to the extent possible. In the Deep Creek sub-watershed, which is a much larger area and includes another relatively large tributary named Glade Creek, we plan to address at least 5 farm and/or septic tanks projects. As stated above, we have pinpointed the specific portions of this drainage that contribute to the high bacterial levels and have begun to identify landowners with whom we can work. We expect that these projects in the sub-watersheds that drain to the upstream listed portion of the Soque River can eliminate much of the bacterial pollution that contributed to its listing and could allow its removal upon completion. 

 

The major subwatersheds draining to the lower listed segment of the Soque (Yellowbank, Beaverdam, and Hazel Creeks) each have a number of bacterial problems and certainly contribute to the failure to meet water quality standards of the Soque’s lower reaches.  Therefore, we will complete farm and/or drain field projects in these sub-watersheds also. The Yellowbank drainage is the smallest of these three but shows some of the highest bacterial counts in our sampling and we will target at least 4 sites in this area. Beaverdam Creek’s drainage is somewhat larger, but we believe that addressing 4 additional sites there can have a significant affect on the problems in that sub-watershed. Hazel Creek sub-watershed is large and very heavily impacted. As described below, we will also be addressing sediment inputs to Hazel Creek and those projects will likely include bacterial pollution reductions also.  In addition to those two projects, we plan to address at least 3 more aimed particularly at fecal coliform pollution sources, for a total of 5 in the Hazel Creek area.  Overall then, we propose to complete at least 20 corrective actions in these 5 sub-watersheds to eliminate sources of fecal contamination in the Soque River and its tributaries.

 

Sediment Pollution Control – In the portion of the Hazel Creek drainage that contributes to the segment listed as an “impaired” water body, we propose to install measures to stabilize stream banks and then reestablish vegetative buffer zones along the streams.  We have identified a number of potential sites already, including ones on Little Hazel Creek, Law Creek, and an unnamed tributary adjacent to the Law Creek drainage. In some of these areas there is major bank instability and sloughing of dirt into the stream channel during higher flows.  We will install tree revetments, tree plantings or other measures as appropriate for each of two sites in this sub-watershed to alleviate these sources. Armored reinforcement of the banks (such as rip-rap) will be used only as a last resort, and will be integrated as much as possible with vegetative solutions.  We will work with technical experts from County government, the NRCS, EPA, and others to design these installations to be most effective and sustainable. We will also do plantings, using native plant species wherever possible, to reestablish adequate buffer zones along these stream segments.  

 

Stormwater Management Measures – Also in the Hazel Creek drainage area, we will identify at least two sites where we can work with land owners to install rain gardens and/or storm water management measures.  These measures will slow runoff and lessen the drastic impacts from increased magnitudes and frequencies of runoff events that have resulted from greater urbanization and impervious cover.  Stormwater BMPs are targeted first towards reducing and preventing pollutants associated with runoff and then with treating or filtering the stormwater to reduce NPS pollutants delivered to streams.

The BMPs listed below are grouped according to the target pollutant for reduction, however, it is anticipated that a number of management practices will result in the effective reduction of both fecal coliform bacteria and suspended sediment loadings.  These BMPs will be used to address the target area “hot spots” identified during the watershed assessment.  In addition to these target pollutants, control and management measures to address stormwater runoff are included as options.  Decreasing the volume of this runoff from urbanizing areas is expected to reduce the concentration of target (and many other) pollutants delivered to streams as well as lessen excessive erosion that comes with periodic high flows associated with increasing area of impervious surfaces.  Descriptions of various BMPs that may be used to control or eliminate pollutant sources are included below and were obtained from four primary sources and are all based on Natural Resources Conservation Service (NRCS) Practice Standards:

2)    U.S. Environmental Protection Agency National Management Measures to Control Nonpoint Source Pollution from Urban Areas, 2005

3)    U.S. Environmental Protection Agency National Management Measures to Control Nonpoint Source Pollution from Agriculture, 2003

4)    Georgia Soil and Water Conservation Commission Field Manual for Erosion and Sediment Control in Georgia, 4th edition, 2002.

 

FECAL COLIFORM BMPs

 

Alternative Water Sources – includes using troughs and tanks to provide livestock with watering sources away from streams to reduce direct fecal coliform contribution and associated erosion.  This measure is often used in conjunction with exclusion fencing.

 

Exclusion Fencing – provides barriers to prohibit livestock from freely entering streams.  Allows for periodic “turning out” of animals to graze in the vegetated buffer for short periods of time thus controlling areas where fecal loadings are present. 

 

Critical Area Planting – establishes permanent vegetation (preferably native plant material) in highly erodible areas to reduce sediment and filter bacteria.  Critical area plantings may reduce sediment runoff by as much as 75%. 

 

Riparian Herbaceous Cover – uses grasses, forbs, and trees directly on banks to protect wildlife habitat, provide wildlife habitat, and to stabilize streambanks and channels.

 

Riparian Forest Buffers – uses trees, shrubs, and grasses to filter surface runoff prior to entering streams.  This practice can reduce sediment loads in surface runoff by 50-75%.

 

Filter Strips – are vegetated areas between cropland, grazing land, or disturbed areas and surface waters to protect water quality.  Filter strips may remove as much as 50-80% of nutrients and sediment from surface runoff.

 

Stream Crossings – provide a stable streambed and reduce erosion where livestock must access streams. 

 

Nutrient Management – assists growers and producers in improving farm management and litter or manure application strategies.

Animal Waste Storage – include composters and stack houses for manure and litter storage.  Proper composting reduces viable bacteria and nutrient concentrations.

 

Septic System Repair – reduces fecal coliform loads where on-site sewage disposal systems are not properly designed, installed, or maintained.

 

Sewer Inspections – can prevent and detect bacterial loading from broken pipes or overflowing manholes.  This practice includes the removal of storm drains that are hooked to sanitary sewers which may overwhelm the capacity of the sewer during periods of heavy rains resulting in overflows.

 

 

SEDIMENT BMPs

 

Heavy Use Area Protection – reduces sediment and bacterial runoff by protecting areas with heavy livestock traffic such as troughs and feeding areas.

 

Pasture and Hayland Planting – prevents soil erosion by establishing native vegetation (preferable) or introduced forages in fields or pastures.

 

Grassed Waterways – are natural channels to slow the flow of water, remove excessive sediment and nutrients, and prevent gully erosion.

 

Field Borders – are permanently vegetated buffers around pastures to reduce soil erosion.

 

Conservation Cover – is the establishment of permanent vegetative cover to prevent erosion and protect water quality on retired agricultural land.

 

Prescribed Grazing – manages grazing animals for long term benefits; promotes vegetative quality and quantity and reduces erosion.

 

Streambank and Shoreline Protection – stabilizes and protects streambanks to reduce erosion and prevent water quality degradation.

 

Stream Channel Stabilization – strengthens or stabilizes the bed or bottom of the channel in very specific instances when normal protection and riparian buffers are inadequate to protect water quality.

 

Tree/Shrub Establishment – slows runoff and allows for increased infiltration of runoff, thus reducing pollutant concentrations.

 

 

STORMWATER BMPs

 

Many urban stormwater BMPs are available and should be considered on a site specific case by case basis (USEPA, 2005).  The importance of proper site design and consideration of new construction is vital, however there are also things that can be done in already developed areas to minimize and treat runoff.  There are two broad categories of stormwater BMPs that will be considered under this plan:  1) BMPs that prevent runoff, and 2) BMPs that treat stormwater to remove potential pollutants before they reach streams.  There are many excellent publications and resources available on BMP selection, installation, and maintenance.  The measures indicated here are not exhaustive.  Additional research is recommended to refine this menu of selections.

 

Runoff Prevention BMPs – are the most effective measures to control NPS pollution.  It is much easier to prevent pollution than to address problems where pollution has already occurred.  These measures are aimed at preventing runoff and subsequent pollutant transport and include:

 

Impervious surface reductions – through street and parking lot design and the use of new technologies like permeable pavement and green roofs.

 

Construction practices – to ensure that grading and clearing are done appropriately and that a system of BMPs is considering prior to development.  This includes measures for mass grading, sequencing development, and maintaining the proper site specific BMPs. 

           

Soil erosion control on exposed soils – using mulches, blankets and mats, vegetative measures, structural methods, inlet protection, silt fence, check dams, and temporary sedimentation basins or traps (GSWCC, 2002).

 

Stormwater Treatment BMPs – are designed to remove pollutants carried in runoff before they reach surface waters and include:

 

Infiltration systems –promote rainfall infiltration prior to runoff.  These measures include basins, trenches, and rain gardens.  When more water soaks in, less runs off (and fewer pollutants are delivered to streams).

 

Filtration systems – to remove excess pollutants from stormwater runoff by bioretention, filter strips, and maintenance of stream buffers.

 

Retention and Detention systems –retain pollutants and detain stormwater for release more slowly over time.  These measures can help reduce stormwater volume and pollutant concentration and help prevent harmful effects of stormwater on aquatic life.

EDUCATIONAL COMPONENT

 

Public education about water quality threats and methods of resource protection are an essential component of this plan.  The educational component will include measures aimed at increasing public awareness of water quality problems and providing solutions. Specific attention will be paid to working with middle school aged children to increase their knowledge of water related issues. Additionally, homeowners will be targeted and encouraged to take control of their stormwater to reduce runoff and increase infiltration. Examples and demonstrations of simple BMPs for residential stormwater will be provided to encourage their implementation. Specific components of the educational program will include:

 

·         Articles about water quality issues in Partnership member newsletters and the local newspaper

·         Continued work with GA Cooperative Extension and the 4-H program on water related curriculum and homeowner BMPs

·         Classroom and lab activities with children in the local school system

·         Speaking engagements with local community and civic groups

·         Purchase of an EnviroScape to demonstrate principles of non-point source pollution in schools and for civic groups

·         Additions to the Partnership website with educational links for teachers to serve as a clearinghouse of water quality information

·         A yearly field day for all Habersham County 6th graders with 8-10 stations covering different aspects of water quality (e.g. macroinvertebrates, chemistry, fish, buffer zones, importance of clean water etc.)

·         A summer day camp for 7th and 8th graders who show an interest in the environmental sciences (based on recommendations from local science teachers). Potential activities include tours of water treatment facilities, trips to local farms to look at agricultural BMPs, field work with water chemistry and aquatic biology/ecology, estimating stream discharge etc.

·         Public meetings to inform citizens about Partnership activities

·         Fact sheets about BMPs that highlight successes

·         Increased participation in Adopt-a-Stream (AAS) by local school, civic, and neighborhood groups.  The SRWP Watershed Coordinator will become a certified AAS trainer and promote the program locally.

·         Storm drain stenciling to increase awareness of the direct connections between runoff and surface waters

 

 

 

 

 

 

 

 

 

 

 

IMPLEMENTATION SCHEDULE

 

Implementation of this plan will begin with the Soque River Watershed Protection Plan Implementation 319(h) grant in April, 2008.  The new grant will run for a period of three years.  Interim milestones for the grant are included in the next section.  A revised implementation schedule will be developed during the grant period to reflect knowledge gained from additional monitoring.  Sites for corrective action will be continually re-prioritized as problems are addressed and new information becomes available.

MONITORING PLAN

 

All monitoring will be in accordance the Soque River Watershed Partnership Quality Assurance Project Plan used for the watershed assessment (approved by USEPA and GAEPD in January, 2005).  The QAPP contains Standard Operating Procedures for field data collection and laboratory analyses to ensure the quality of the data.  In addition to data collected during the watershed assessment, it is suggested that fish data be added to the biological information already available. 

 

Routine monitoring for sediment and bacteria will continue and we will work to refine “hot spot” locations for corrective action.  The goal is to ensure that BMPs are implemented in places where they will result in water quality improvements and progress towards our goal of 303(d) de-listing.  In all cases where BMPs are installed or management measures implemented, both pre and post activity monitoring will occur (upstream/downstream).  We will evaluate and assess physical, chemical and biological variables, as applicable. 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

ADDITIONAL RECOMMENDATIONS

 

In addition to the specific implementation activities mentioned in this document, a number of local measures are available and recommended to enhance water quality protection.  Many of these recommendations may be addressed thorough proper enforcement of existing laws and regulations (e.g. the Georgia Erosion and Sediment Control Act).  The current draft Comprehensive Plan for Habersham County and associated localities contains a number of sections that deal with natural resource protection.  The Comprehensive Plan should be used as a guide, in conjunction with this Watershed Protection Plan, for making decisions about the use and protection of water (and other natural) resources in the watershed and county.  If not currently addressed, it is also recommended that municipalities investigate the possibility of local ordinances, guidelines, or mechanisms for:

 

·         Mass grading

·         Stream buffer protection

·         Stormwater management

·         Performance based zoning

·         Protection of sensitive ecosystems and water supply watersheds

·         Farmland preservation

·         Water conservation and increased efficiency

·         Limiting impervious surfaces

·         Greenspace

·         Slope restrictions for development

·         Transferable development rights

·         Land acquisition

·         Conservation easements

 

Consideration in implementing local water quality and quantity protections must also be given to the Comprehensive Statewide Water Management Plan that recently passed as a resolution in the Georgia Legislature.  Additional recommendations for citizens and localities will be added as applicable for the term of implementation of this grant and beyond.  Model ordinances to address some of the issues above are available through the River Basin Center at the University of Georgia’s Institute of Ecology (www.rivercenter.uga.edu).  Additional codes and ordinances are available at www.stormwatercenter.net and www.municode.com.  It is also recommended that the SRWP seek lessons learned from other watershed partnerships across the state and nation (e.g. the partnership to develop and implement the Etowah Habitat Conservation Plan).

 

 

 

 

 

 

TECHNICAL AND FINANCIAL ASSISTANCE NEEDED

 

Funding for three years of implementation of the Soque River Watershed Protection Plan has been secured via a Clean Water Act § 319(h) grant administered through GAEPD.  A project budget for the first three years of implementation is included in Table 7.  It is important that the work started during this time be continued over a longer period in order to meet the CWA goal to “restore and maintain the chemical, physical, and biological integrity” of surface waters in the Soque River Watershed.  The ultimate success of this project will be judged by our ability to implement management and protection strategies that result in documented water quality improvements in 303(d) listed and other stream segments.  The total amount of funding needed to meet these goals is unknown at this time.  The initial three year implementation will provide much insight as to how much capital may be needed to meet and maintain the pollutant load reductions necessary to meet water quality standards.  The SRWP will investigate additional sources of funding to achieve these goals (included below).  More grant possibilities will be considered and researched during the implementation phase from available sources.
