2019 Parmly Gully Stabilization Project on Green Lake
A large, actively eroding gully has existed on the campus of Parmly, a senior living complex in Chisago City, for at least 50 years. The gully is on the banks of Green Lake, which is at high risk for becoming impaired in the near future. The Parmly gully project is identified as a source of untreated stormwater and phosphorus loading in the Chisago City urban subwatershed retrofit analysis report. Stabilization of the gully will provide a 20% reduction in phosphorus loading to Green Lake. The staff of Parmly is in full support of the project and a design is complete.

for grants to protect and restore surface water and drinking water; to keep water on the land; to protect, enhance, and restore water quality in lakes, rivers, and streams; and to protect groundwater and drinking water, including feedlot water quality and subsurface sewage treatment system projects and stream bank, stream channel, shoreline restoration, and ravine stabilization projects. The projects must use practices demonstrated to be effective, be of long-lasting public benefit, include a match, and be consistent with total maximum daily load (TMDL) implementation plans, watershed restoration and protection strategies (WRAPS), or local water management plans or their equivalents. A portion of these funds may be used to seek administrative efficiencies through shared resources by multiple local governmental units.
The BWSR Pollution Reduction Calculator estimates that 112 pounds of phosphorus and 112 tons of sediment will be prevented from entering Green Lake annually.
This project has resulted in an estimated annual reduction of 117.64 pounds/year of Phosphorus, Sediment (soil) savings 117.64 tons/year, Sediment (TSS) reductions 117.64 tons/year. This was also completed an installation of a grade stabilization structure that repaired and stabilized 400 feet of channelized gully.
