Staring Lake Restoration

The City of Eden Prairie and the Riley Purgatory Bluff Creek Watershed District are jointly developing and implementing a restoration plan for Staring Lake that includes nutrient reductions and carp management. The City of Eden Prairie, through a comprehensive pond inspection program, identified high priority ponds and subwatersheds for nutrient reductions in the Staring Lake watershed. Several ponds were identified as excellent candidates for iron enhanced sand filtration.
Typically, the sand and iron filter is cut into the safety bench of a pond with a drain tile, the drain tile is connected to the outlet structure, and the outlet structure is modified to force water through the filter for small, frequent rainfalls (1-inch or less). Rainfalls greater than the filter design will pass through the outlet structure as originally designed with no impact to up- or downstream properties.
