Island Lake Wpa in Morris, Minnesota, is a Federal-owned Fish and Wildlife Pond managed by Ducks Unlimited. Completed in 1990, this Earth dam structure stands at 16 feet high and spans 290 feet in length, with a storage capacity of 700 acre-feet. Situated on the Pomme de Terre River, this low hazard dam serves as a crucial resource for waterfowl and wildlife conservation in the area.

Despite its low hazard potential, Island Lake Wpa is classified as having a very high risk due to its location and surrounding environment. While the dam itself is in good condition and has not been recently inspected, its emergency action plan and preparedness measures remain unclear. With a drainage area of 3 square miles and a maximum discharge of 160 cubic feet per second, this dam plays a significant role in water resource management in the region.

Although the dam's condition assessment is marked as "Not Rated," its strategic location and purpose as a wildlife sanctuary make it a vital asset for climate and water resource enthusiasts. As efforts continue to maintain and monitor this structure, Island Lake Wpa stands as a testament to the importance of sustainable water management practices in safeguarding our natural ecosystems.
