What's being done
In 2011, the Lower Big Sioux River watershed, along with three adjacent major watersheds located in the Missouri River Basin, will be starting the MPCA’s major watershed restoration and protection project process. Data collection, assessment, and implementation will occur over 10 years. Each project begins with intensive monitoring, where biological data is collected along with physical and chemical data of streams and lakes in selected watersheds. There are 138 proposed stream sites to be sampled for biological data, 23 stream sites for water quality and one site for fish tissue.
