This project will beneficially utilize dredge material to create islands that will provide a variety of habitat for fish and wildlife.
Pigs Eye Lake is located in Ramsey County, just east of downtown St. Paul, Minnesota, in upper Pool 2 of the Mississippi River. Due to the lake’s proximity to the Mississippi River, the lake water level is controlled by the level of the river. The lake is located in the Mississippi River Bottomlands Subwatershed.
The lake is a valuable wildlife habitat resource and is utilized by a variety of birds and mammals. However, due to high turbidity and phosphorus levels, the lake is classified as hypereutrophic. Sedimentation, low transparency and nutrient loading have caused the water quality and habitat suitability in the lake to be poor. Additional factors such as wind fetch and high carp populations are also impacting the water quality and habitat suitability.
The project will utilize clean dredged material from Pool 2 to improve the ecosystem in Pigs Eye Lake. The project includes the construction of six islands of various sizes within the lake, creating a range of habitat types for fish and wildlife. These islands will also reduce wind and wave action, improving vegetation in the lake, creating thermal shelter for waterfowl and protecting further shoreline erosion.
