Project Overview

In partnership with the City of Coon Rapids, the Coon Creek Watershed District will address Coon Creek's aquatic life and recreation impairments by reducing nutrient and bacteria loading attributable to stormwater runoff from an 822-acre urban catchment. The project will retrofit an existing in-line rate control pond with a large iron-enhanced sand filter bench to target dissolved phosphorus, reducing TP loading to Coon Creek by 69 pounds per year. It will also incorporate bio-char into the filter media mixture to reduce E. coli loading as recent laboratory studies have shown that biochar can remove over 90% of E. coli from synthetic stormwater.

for grants to protect and restore surface water and drinking water; to keep water on the land; to protect, enhance, and restore water quality in lakes, rivers, and streams; and to protect groundwater and drinking water, including feedlot water quality and subsurface sewage treatment system projects and stream bank, stream channel, shoreline restoration, and ravine stabilization projects. The projects must use practices demonstrated to be effective, be of long-lasting public benefit, include a match, and be consistent with total maximum daily load (TMDL) implementation plans, watershed restoration and protection strategies (WRAPS), or local water management plans or their equivalents. A portion of these funds may be used to seek administrative efficiencies through shared resources by multiple local governmental units.
