Lake Ida Targeted Phosphorus Reduction Project
A feasibility study was completed to determine the best options for addressing phosphorus loading to Lake Ida, and will be completed through this grant. These practices include: construction of a 1,899 feet of channel along the wetland edge, repair 741 feet of existing channel, construct one stilling basin, and repair an existing sediment pond. Implementation will prevent loading of 240 pounds/year of phosphorus to Lake Ida. The wetland is leaching phosphorus from legacy pollution and is a major component of the phosphorus load. A subwatershed assessment was also completed for the lake in order to identify other sources of phosphorus. However, none are as significant as the wetland. The DNR lists Lake Ida as highest priority in terms of phosphorus sensitivity, high in biological significance, and is a first ranked waterbody.
(Projects and Practices)(b) $16,000,000 the first year and $16,000,000 the second year are for grants to local government units 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 this money may be used to seek administrative efficiencies through shared resources by multiple local governmental units. Up to 20 percent of this appropriation is available for land-treatment projects and practices that benefit drinking water.
This project will prevent 240 lbs/year of phosphorus from entering Lake Ida. 200lbs/year by utilizing a low flow channel around the wetland; 40lbs/year by fixing an existing sediment pond. This reduction will help prevent Ida from becoming impaired.
