MCWD, in partnership with the City of Victoria, retrofitted existing stormwater ponds by installing a filtration system to remove dissolved phosphorus. The retrofit increased stormwater capture capacity to cover 22 acres of land. This project ensures that new development in Victoria’s downtown is supported with adequate stormwater treatment facilities.

The pond retrofit facilitated the capture and treatment of stormwater from land that would have been exempt from the regulatory stormwater rules, meaning that now even more stormwater is filtered before entering East Auburn Lake than necessary.

This project is a result of the ongoing coordination and communication with partners about plans, priorities, and opportunities for collaboration in the Six Mile Creek-Halsted Bay subwatershed, facilitated by the Six Mile Creek-Halsted Bay Subwatershed Partnership, which MCWD convened in 2015. The subwtershed partnership includes Carver and Hennepin Counties; Cities of Minnetrista, St. Bonifacius, Victoria, and Waconia; Laketown Township; Carver County Soil and Water Conservation District; and Three Rivers Park District.
