Lake Shetek Outlet, located in Murray County, Minnesota, serves as a crucial water management structure on the Des Moines River. Managed by the Minnesota Department of Natural Resources (MNDNR), this gravity dam stands at a height of 8 feet and has a structural height of 12 feet, with a length of 115 feet. The reservoir created by the dam has a storage capacity of 30,064 acre-feet and a normal storage level of 19,040 acre-feet, covering a surface area of 3,370 acres.

The dam, completed for purposes other than flood control, has a low hazard potential and is deemed to be in satisfactory condition as of the last assessment in May 2018. Despite not having a spillway, Lake Shetek Outlet can discharge up to 3,500 cubic feet per second in cases of excess water flow. While the dam does not have outlet gates or associated locks, it plays a vital role in regulating water levels and ensuring water resource management in the region. With its strategic location and functionality, Lake Shetek Outlet is an integral part of the water infrastructure in the area, contributing to the overall environmental and climate resilience of the region.
