Big Carnelian Lake Stormwater Quality Improvements Phase I
This project proposes to collect and treat 32 acres of stormwater flowing directly into Big Carnelian Lake with no water quality treatment. A 15,000 ft? bioinfiltration basin will treat 87% of the annual discharge and reduce 7.0 lbs. total phosphorus and 3 tons of sediment discharging into Big Carnelian Lake each year. Big Carnelian Lake is a high quality recreational lake with a public access and declining water quality trends. This is largest source of untreated urban stormwater discharging into the lake identified in the Big Carnelian Lake Subwatershed Analysis.

(Projects and Practices)(b) $10,762,000 the first year and $11,504,000 the second year are for grants to local government units 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. Up to 20 percent of this appropriation is available for land-treatment projects and practices that benefit drinking water.
Install a 15,000 ft? infiltration basin and piping to collect and treat stormwater discharging to Big Carnelian Lake with no treatment. Decrease stormwater volumes by at least 2.8 ac.ft./yr., TP by 7.0 lbs./yr. and TSS by 3.0 tons by year.
