Little Sac Restoration and Improvement Project

Targeting non-point source pollution in the heart of our drinking watershed

Project Summary:

Watershed Committee of the Ozarks was awarded a subgrant agreement from the Missouri Department of Natural Resources in the amount of $428,461 which will provide $255,551 dollars and $172,910 in local match to improve the drinking watershed of Springfield and Greene County. The project will focus on reducing the loading of pollutants identified in the 303(d) watershed(s) and accompanying Total Maximum Daily Load (TMDL) for the Upper Little Sac River, as described and recommended in the watershed based plan for that basin, by targeting the sub-watershed for the implementation of BMPs that will reduce nonpoint source pollution. The approach of this project will be to monitor the performance of the selected best management practices (BMPs). Practices will include a demonstration of Longitudinal Peaked Stone Toe Protection (a method of stabilizing eroding banks), prescribed grazing systems, bank vegetative buffers, and alternative livestock watering sources at individual sites and regional levels in the sub-watershed, as well as estimate sub-watershed pollutant loading improvements at sub-watershed outlets. The BMP designs and improvements will then be incorporated into criteria manuals for future policies and ordinances addressing agricultural and urban water quality. Project partners, namely City Utilities of Springfield, the Greene County Soil and Water Conservation District, and the Missouri Department of Conservation will assist in BMP implementation and monitoring of the projects implemented.

On March 2, 2016 the Missouri Department of Natural Resources awarded an additional $104,511.67 to the original award of $255,551 in federal funding, for a total of $360,062.67. The budget and projects periods will be extended from March 31, 2017 to April 30, 2018.


The purpose of the project is to implement best management practices (BMPs) to improve water quality, decrease soil erosion, and improve aquatic life. The project will also include water quality monitoring and nonpoint source/project-specific educational activities. The portion of the HUC 12 watershed in Greene County (Upper Little Sac River) will be the project focus area and include the following activities:

Best Management Practices:
• One Demonstration LPSTP Practice of approximately 850 feet in length
• Three Prescribed Grazing Systems with an approximate total of 240 acres completed
• Vegetative Buffer Strips (quantity depends on size of practices and funding available)
• Stream Restoration Practices (quantity depends on size of practices and funding available)

Water Quality Monitoring:
• Weekly samples May through September at a minimum of 5 sites on the Upper Little Sac River and its tributaries by City Utilities of Springfield
• Quarterly samples October through March at a minimum of 5 sites on the Upper Little Sac River and its tributaries by City Utilities of Springfield
• WCO to provide a watershed map marking where monitoring will occur

Project focused education:
• One project specific HUC 12 watershed factsheet
• Three developed press releases and newsletters
• One nonpoint source BMP workshop, public meeting
• One project webpage, and one project specific sign located at the Watershed Center
• Two canoe tours for county, city and WCO officials to see before and after affects from projects
