Lake Calhoun Outlet, located in Kandiyohi, Minnesota, serves as a critical water resource structure on the Crow River Middle Fork. Built in 1937 by the Works Progress Administration (WPA-C), this gravity dam stands at a height of 7 feet and has a hydraulic height of 3.5 feet, providing essential regulation for the surrounding area. With a normal storage capacity of 3,726 acre-feet and a drainage area of 11.8 square miles, the dam plays a crucial role in flood control and water management.

Owned and regulated by the Minnesota Department of Natural Resources, the Lake Calhoun Outlet is inspected regularly to ensure its structural integrity and functionality. The dam has a low hazard potential and is currently assessed to be in fair condition as of June 2016. With a maximum discharge capacity of 1,235 cubic feet per second, the outlet can efficiently release excess water during peak flow events, reducing the risk of downstream flooding. Additionally, the dam's association with the Crow River Middle Fork underscores its importance in sustaining the local ecosystem and supporting various ecological functions.

As a key component of the St. Paul District's water infrastructure, the Lake Calhoun Outlet embodies the intersection of water resource management and climate resilience efforts in Minnesota. With a history of serving the community for over eight decades, this gravity dam continues to play a vital role in safeguarding against flood hazards and ensuring sustainable water supply for the region. Its strategic location and design reflect a commitment to addressing the challenges of climate change and maintaining the balance between human needs and environmental conservation in the Crow River watershed.
