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.

As part of the Little Sac Restoration and Improvement Project on November 6-8, 2017 the Watershed Committee of the Ozarks hosted a hands-on educational workshop, which coincided with the construction of a stream stabilization project on the Little Sac River. Forty people participated in the workshop to help construct the Longitudinal Peaked Stone Toe Protection streambank stabilization project, which includes an engineered floodplain bench, bendway weirs, unrooted live pole plantings, vegetated and curved keys, and rooted stock plants. Mr. Dave Derrick a Potomologist and Stream Stabilization Specialist with River Research & Design, Inc. from Vicksburg, MS with over 20 years’ experience lead the workshop and provided construction oversight.

This project helps reduce nonpoint source pollutants from entering the Little Sac River, which will benefit our drinking water supply for many years to come. We are very thankful to all of our community partners that made this project possible including the landowners, the grant steering committee, Missouri Department of Natural Resources, Greene County, Missouri Department of Conservation, Wildscape Environmental Services and all of our workshop attendees!
