James River Watershed Management Plan: Lower James River & James River Arm of Table Rock Lake Sub-watersheds August 24th, 2009 U.S. Environmental Protection Agency Region7, through the Missouri Department of Natural Resources, has provided partial funding for this project under Section 319 of the Clean Water Act (MoDNR Subgrant #G07-NPS-07) Acknowledgements This James River Basin Watershed Management Plan was completed with assistance from many partners including Ozark Environmental and Water Resources Institute (OEWRI), Midwest Environmental Consulting (MEC), The Forrester Group, Christian County Soil and Water Conservation District (CCSWCD) and Table Rock Lake Water Quality Inc. (TRLWQ). The James River Basin Partnership (JRBP) facilitated the basin-wide planning effort including coordination of the various stakeholder groups for sub-watersheds or portions of the James River Basin watershed. Water quality data and watershed characteristics were compiled by MEC and OEWRI. This information was utilized by stakeholders, made up of local watershed residents and business people, throughout the planning process as a reference to the known state of the watershed. This water quality data also served as a tool for the stakeholders to make better informed decisions regarding land management practices needed to help protect and improve the water quality. OEWRI also developed methodology for determining nutrient loading and load reduction expectations for the sub-watersheds. Table Rock Lake Water Quality Inc. (TRLWQ) administered the watershed management planning process for the Lower James River Basin sub-watershed and also for the James River Arm of Table Rock Lake sub-watershed. Christian County Soil and Water District administered the watershed management planning process for the Finley River sub-watershed and the James River Basin Partnership administered the watershed management planning process for the Middle James sub-watershed. The Forrester group, an environmental management consultant company, was the moderator and facilitated stakeholder meetings in each of the sub-watersheds with the aim of providing a detailed planning document for water quality preservation and management throughout the James River Basin watershed. 2 Table of Contents Introduction A.

This effort proceeds by highlighting water quality issues within individual sub-watersheds with the aim of completing a comprehensive, region-based watershed management plan for the entire James River Basin. Currently, the James River is listed as impaired from excessive nutrient concentrations on the Environmental Protection Agency’s (EPA) 303(d) impaired waters list. The creation of a watershed management plan for the James River watershed will help to protect and improve water quality in the James River and in Table Rock Lake. This plan is meant to identify pollutant sources, identify better management practices to be implemented, set reachable goals and a timeline for implementation, and establish an evaluation and monitoring program to determine success of implemented projects/programs. Development of a watershed management plan will increase the success of future projects, help to determine where efforts should be focused, fulfill specific grant application requirements for securing future funding, assist other organizations and municipalities in water quality related efforts, and provide insight for creation of more efficient implementation and/or education budgets for future projects. The watershed management plan was developed using a stakeholder driven process that allowed input from over 80 stakeholders, so far, to assist watershed managers in future implementation, education/outreach, and monitoring efforts that will occur throughout the basin. This plan will act as a road map to improve the water resources throughout the basin and prioritize efforts for reduction of nonpoint source pollution. This watershed management planning process was implemented using the EPA’s 9 key elements for watershed management plan development. These basic elements are listed as follows: 1. Identify the sources that will need to be controlled to reduce pollution levels. 2. Estimate the reductions expected. 3. Describe the management measures needed to achieve the pollution reductions. 4. Estimate of the amounts of technical and financial assistance needed. 5. Information/education components needed. 6. Schedule or timeline for the management plan. 7. Identify measurable milestones for determining whether management plan is working. 8. Set criteria to determine whether pollution reductions are being achieved over time. 9. Add a monitoring component to the plan that evaluates the effectiveness of the plan. A. The James River Basin The James River watershed is located in the Ozark region of Southwest Missouri. It is approximately 931,050 acres or 1455 square miles in size. Portions of eight counties 4 Background Data – James River Watershed (Stone, Christian, Barry, Lawrence, Greene, Webster, Wright, and Douglas) drain into the James River which eventually flows into Table Rock Lake (Figure 1). There are approximately 289 miles of streams with permanent flow, 74 miles of intermittent streams, and numerous losing streams within the James River Basin where all or most of the flow enters underground channels. Streams in the Basin are characterized by narrow bottoms, rock and gravel bottom strata, high gradient, and are surrounded by high relief outside of the flood plains. The Ozark region, including the James River watershed, is well known for its karst geology. Sinkholes are present throughout the entire basin, especially in the Finley and upper Flat Creek areas. The majority of the land within the basin, an estimated 74,400 acres, is privately owned, although there are several thousand acres of National Forest. Land uses in the watershed include urban development, agricultural use including row crops and livestock, and forested areas. The James River Basin encompasses the metropolitan area of Springfield and many rapidly growing communities such as Ozark and Nixa. Growth of these communities has greatly increased population pressure and demands the natural resources of this river which is used for drinking water and to carry wastewater from municipal treatment facilities. Tourism is also major industry in the James River and Table Rock Lake Basins. The James River and its tributaries are also used frequently for floating, swimming, and fishing for bass, sunfish, and catfish. Within the James River Basin the following streams are either listed on EPA’s 303(d) list of impaired wastewaters or have a completed Total Maximum Daily Load estimate (TMDL): James River, Wilson Creek and Pearson Creek. The pollutants identified as responsible for these impairments include nutrients, unknown toxicity, bacteria, and mercury. In 1998 three segments of the James River were listed as impaired for nutrients. These segments extend from the river’s headwaters to its mouth on Table Rock Lake. The Missouri Department of Natural Resources (MoDNR) cited phosphorus from sewage treatment plants, and runoff of phosphorus and nitrogen from urban and agricultural development as being of particular concern in the James River Basin. Elevated nutrient levels, particularly phosphorus, have also been attributed to causing decreased clarity due to algae growth in Table Rock Lake (MoDNR, 2004a). The EPA approved the James River TMDL in May 2001, which is to be completed in two phases. Phase I of the TMDL includes the implementation of phosphorus removal efforts at select wastewater discharge facilities. The Springfield Southwest Wastewater Treatment Plant, which has been cited as the most significant nutrient loading source, completed its phosphorus removal upgrades in March 2001. Phosphorus removal upgrades at all other facilities were planned to be completed by November 2007. Phase II of the James River TMDL primarily addresses the reduction of nonpoint nutrient loadings (MoDNR, 2001). Substantial efforts to reduce point source and nonpoint source pollution have been occurring within the James River watershed. According to volunteer monitoring, upgrades to wastewater treatment plants have already shown improvement to water quality within the James River arm of Table Rock Lake. A number of projects now completed or ongoing have also focused on agricultural land use and implementation of 5 Background Data – James River Watershed best management practices.
