Red River Basin Reservoir Nutrient Load Reduction –<br />
2014<br />
Sponsor: RRBC<br />
Funding: Section 319 (Grant) $289,998<br />
Purpose: Determine if vegetated flood storage reservoirs<br />
(current and future) can provide a 50 percent reduction<br />
in nutrient loading to selected tributaries that feed the<br />
Red River. This project will explore the use of floodwater<br />
impoundment structure for nutrient reduction by<br />
redesigning the cell management to reroute the stream<br />
flow through vegetated treatment cells. It is expected<br />
that the treatment cells will capture and hold nutrients<br />
both in sediment and in the vegetation (i.e., cattails);<br />
however, the nature of nutrient movement and storage<br />
is dynamic. This project will attempt to clearly define<br />
nutrient flux in the contributing watershed and both<br />
inside and outside of the Impoundment’s cells. This<br />
project will serve as a test pilot to aid with future nutrient<br />
control BMP design.<br />
