Calhoun Area Water Control and Habitat Enhancement Project

The Middle Fork Crow River Watershed District (MFCRWD), in partnership with the Minnesota Department of Natural Resources (DNR) is leading a major restoration initiative within the Dietrich Lange Wildlife Management Area (WMA). This project aims to replace aging water control structures for both Calhoun and Green. The centerpiece of the effort is the replacement of two outdated dams and a timber bridge located along the Middle Fork Crow River with more sustainable, fish-friendly rock arch rapids and a modern vehicle bridge. These naturalized features will maintain necessary court ordered water elevation control while re-establishing ecological connectivity between the lakes, benefiting fish passage and habitat quality.

The project is supported by $1.9 million in secured funding from multiple sources. This includes $1.325 million from the Legislature’s Get Out MORE (Modernize Outdoor Recreation Experiences) initiative, $125,000 in Wildlife Betterment of Lands bonding, and $450,000 in Natural Resource Asset Preservation bonding to support bridge replacement. In addition to modernize outdoor infrastructure while improving ecosystem resilience, the upgrades will provide accessible opportunities for anglers, thanks to the strategic flat rock design of the rapids, which will concentrate fish in specific flow areas.

Construction and associated closures are scheduled to begin in late summer, with the project area expected to be closed for access around September 15, 2025. This collaborative endeavor reflects a shared commitment to sustainable natural resource management and recreation access, made possible by the dedication of the project’s partners.
