Preserving Silver Lake, a recreational resource in Maplewood, North St. Paul

Valley Branch Watershed District’s Clean Water Fund project focuses on reducing phosphorus via stormwater treatment, bio-retention basin, to maintain quality of metro lake book-ended by parks; known for public boat launch, piers, swimming beach

Silver Lake attracts anglers to Joy Park in Maplewood, seen here, and to Silver Lake Park in North St. Paul on the south shore. It supports sunfish and largemouth bass, along with walleye, northern pike, other panfish and channel catfish, according to the Minnesota Department of Natural Resources website. Both parks have fishing piers. Joy Park is the site of Maplewood’s only public boat launch. Contributed Photos
Spring ephemerals including bloodroot grow in Maplewood’s Joy Park on the north shore of Silver Lake. Other early spring blooming wildflowers found in the park include trout lilies, violets, Solomon’s seal, large-flowered trillium and blue flag iris.
Protecting Silver Lake’s water quality is the goal of Valley Branch Watershed District’s phosphorus reduction work supported by a Clean Water Fund grant from BWSR. The 76-acre lake lies south of Interstate 694.
A spent lime filter on the north side of Silver Lake diverts stormwater to a basin and then to a wetland, treating the water before it enters the lake, removing dissolved phosphorus by binding it to calcium carbonate. A restored bio-retention basin on the south side of the lake allows nutrients and the pollutants it carries to settle out. Pollinator-friendly native species planted at the site will improve habitat — a secondary project goal.
