Birch Lake Hot Spot Remediation
An existing wetland in the northeast subwatershed for Birch Lake has been identified as a source of phosphorus to the lake. This project will modify the outlet of the wetland. This will provide extended detention to minimize impacts to upland vegetation and provide more bounce and filtration capacity. Additionally, an installed iron-enhanced sand filtration system will result in an annual phosphorus reduction of 8 pounds.

$6,882,000 the first year and $12,618,000 the second year are 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.
Capture 8.1 lbs/yr of Total Phosphorus annually from a targeted subwatershed of Birch Lake through a retrofitted iron-enhanced sand filter and detention system.
Project was completed as proposed. Funds were used for education and outreach to adjacent landowners, engineering and technical assistance, and installation of an iron-enhanced sand filter and detention structure retrofitted at the outlet of an existing wetland.
