The reconstruction of County Road 12 and Sunset Avenue in the city of Prior Lake afforded the District with an opportunity to improve and increase a wetland with marginal resource benefit which included an agricultural drainage ditch. The project is now almost complete and will enhance flood control and capture phosphorus and sediment before they reach Spring Lake and other downstream water bodies. It will also treat runoff from two highways , city roads as well as an upstream 60 acre agricultural area.
The District will continue to monitor and maintain the vegetation around the wetlands until it has been successfully established. Also, a carp barrier has been designed for this location and will be installed this fall by the City of Prior Lake.
The District will also be working with the City of Prior Lake to place two interpretive signs at this location, explaining the many benefits of the improvements that have been accomplished at this site.
