PLSLWD Announces "Watershed Week" News

Join the Prior Lake-Spring Lake Watershed District for Watershed Week, July 7-13.

Swamp Lake Iron Enhanced Sand Filter Project

The Swamp Iron Enhanced Sand Filter (IESF) is an important part of watershed nutrient reduction and preventing nutrients from reaching the downstream County Ditch 13 system, Spring Lake and Prior Lakes. The Swamp IESF is expected to filter, bind with excess nutrients, and remove 89 lbs of Phosphorus per year, and presents one of most cost-effective, and far-reaching solutions in the watershed strategy.

Spring Lake Shoreline Restoration Project

Shoreline restoration prevents soil erosion from entering our lake, as well as providing filtration for other pollutants. Native plants provide bank stabilization, water filtration, and habitat improvement. Three main shoreline restoration techniques were used to stabilize these areas: brush bundles, cedar revetment and native plantings with erosion control blanket.
