A watershed is defined as: all the land (and everything on it) that drains into a stream or lake; a drainage basin.
Storm Lake has 14,400 acres in its watershed. The LPA is committed to working with individuals, businesses and government entities on projects that improve the quality of the water that runs into the lake.
Projects that have been done within the watershed include the installation of Riparian areas and buffer strips to prevent Ag runoff along streams that feed Storm Lake.

Within the urban centers rain gardens and filtering detention ponds have been constructed to help filter storm water runoff in natural ways. Local industry and commercial business have also done their part by constructing storm water components as part of their new facilities.

The City of Storm Lake is also actively involved in a number of community educational opportunities including partnerships with local schools to teach storm water curriculum to elementary students.
