Purpose
The purpose of the project is to stop erosion along tribal lands on the southeast side of Big Sand Lake in Wisconsin while enhancing access to the water for cultural practices.
Location
Fed by groundwater, Big Sand Lake is a clear, soft water lake that has varying levels of algae growth within the year, affecting lake health. The lake, located in Burnett County, Wisconsin, is typically 1,434 surface acres with a maximum depth of 55 feet.
The Sand Lake St. Croix Tribal Community is situated on Big Sand Lake along its southeast shoreline. The St. Croix Tribe hosts a swimming beach and winter boat landing. Tribal members grow and collect wild rice and fish of a variety of species, including bluegill, black crappie, walleye, largemouth bass, yellow perch and northern pike, in Big Sand Lake.
Description
Tribal elders have indicated that these areas were historically good ricing spots but have decreased in size over time. No harvests have occurred for many years. Additionally, approximately 2,000 linear feet of shoreline is actively eroding into tribal land along the southeastern bank of Big Sand Lake. The eroded area is progressing toward Angeline Avenue, approximately 50 feet from Angeline Avenue at the nearest point. The shoreline erosion is also affecting a local beach. Tribal members indicate that runoff, wave action and springtime ice heaving along the tribal lakeshore are causing the erosion and environmental degradation. The lake is more than 1 mile wide at this location, which results in a large fetch for waves to develop.
Status
The U.S. Army Corps of Engineers and tribal partners completed a feasibility study in August 2022, evaluating various alternatives for the permanent stabilization of the lake shoreline and the protection of the structural integrity of Angeline Avenue. The feasibility study determined and compared alternative methods for achieving restoration by developing planning level cost estimates and identifying data gaps and then collecting the data needed to complete the assessment of alternatives.
Initial funding was received in fiscal year 2018. Additional funding was made available for the U.S. Army Corps of Engineers to begin design work in winter 2023. The final design completion and construction contract award are anticipated in fiscal year 2025. The project is expected to be fully federally funded.
Authority
The Tribal Partnership Program (Section 203 of the Water Resources Development Act of 2000) authorizes activities related to the study, design and construction of water resources development projects substantially benefiting Native American tribes. The nonfederal sponsor for this project is the St. Croix Chippewa Indians of Wisconsin.
Funding
Federal funds allocated to date $660,000
