Improving the Water Quality of Green Lake
Green Lake is a popular and regionally significant lake. Monitoring data collected on Green Lake indicates that the lake's water quality is declining. Over recent decades, development in the City of Spicer and around Green Lake has increased dramatically, resulting in much higher percentages of impervious surfaces such as parking lots, driveways and roads. The resulting increase in runoff velocities and volumes require the incorporation of stormwater infrastructure to accommodate water that previously infiltrated soils.
This project provides solutions to the water volume and water quality issues threatening Green Lake's water quality. Five initiatives will be implemented, including the daylighting of a newly developed riffle and pool lined channel, a raingarden/biofiltration program to accompany the channel, a parking lot retrofit, a biofiltration cell and hydrodynamic separator to enhance a previously installed project and the stabilization of a heavily eroded channel due to stormwater influences.
The 20-member BWSR board consists of representatives of local and state government agencies and citizens. Members are appointed by the governor of the state of Minnesota consistent with Minnesota Statutes 103B.101. Board members at the time the grant was made were: County Commissioner Appointees: Quentin Fairbanks; Tom Loveall; Brian Napstad; Soil and Water Conservation District Appointees: Paul Langseth, Louise Smallidge and Bob Burandt; Watershed District or Watershed Management Organization Appointees: Gene Tiedemann, LuAnn Tolliver and Todd Foster; Citizen Appointees: Paul Brutlag ; Gerald Van Amburg; John Meyer; Cities & Townships: Sandy Hooker -Township; Christy Jo Fogarty -Metro City; Keith Mykleseth -Non-Metro City; Agency: Chris Elvrum - Minnesota Department of Health; Rebecca Flood - Pollution Control Agency; Tom Landwehr - Department of Natural Resources; Matt Wohlman - Minnesota Department of Agriculture; Faye Sleeper - Minnesota Extension Service;

(a) $13,750,000 the first year and $13,750,000 the second year are for pollution reduction and restoration grants to local government units and joint powers organizations of local government units to protect 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 (SSTS) projects and stream bank, stream channel, and shoreline restoration projects. The projects must be of long-lasting public benefit, include a match, and be consistent with TMDL implementation plans or local water management plans.

A 20' x 80' x 4' woodchip bioreactor was installed on an out-letting field tile before it reaches Diamond Lake. Final pollution reduction estimates: 6 lbs/yr nitrates, 135 lbs/yr phosphorus, 149 tons/yr sediment (TSS), 138 tons/yr soil loss reduction
The source of additional funds varies from project to project, but generally consists of federal, local and non-public sources.
