Rain water runoff poses a significant threat to lakes and streams throughout Isanti County. Excessive water and pollutants that are carried into water bodies via rainwater runoff can have devastating effects on the health of lakes and streams and surrounding habitat.
In response to these issues, SWCD staff conduct Subwatershed Assessments (aka. SRAs or SWAs) to identify retrofit opportunities in watersheds that are significant contributors to the degradation of high priority water bodies. Projects identified during the process have the goal of improving water health, increasing groundwater recharge, and reducing rainwater runoff amounts. This information is critical and is required by the SWCD as a first step to the grant application process.
The assessment process includes: 1) computer scoping; 2) field investigations; 3) BMP treatment ranking and 4) promotion/education.
