Upper Watershed Blueprint

Upper Watershed Blueprint Report (March 2021)

In order to approach Upper Watershed stormwater management more comprehensively, the Prior Lake-Spring Lake Watershed District worked with Wenck to develop the Upper Watershed Blueprint. The Upper Watershed Blueprint will be used as a prioritized implementation roadmap for the PLSLWD and local partners to improve water quality conditions and reduce flooding. The goals of this Blueprint are to:

Recommend and prioritize programs, projects and policy to reduce phosphorus and runoff volume,
Identify partners and potential funding sources, and
Detail a 10-year schedule for prioritized program and project implementation.
