The Moose River Project in Grygla, Minnesota, is a crucial infrastructure designed and managed by the Red Lake WD to reduce flood risks in the area. Completed in 1986, this earth dam stands at a height of 16 feet and a length of 66,000 feet, with a storage capacity of 54,000 acre-feet. Situated on the Moose River, this project plays a vital role in protecting the surrounding community from potential flooding events, with a very low hazard potential and a very high risk assessment rating.

Managed by the Minnesota Department of Natural Resources (MNDNR EWR) and located in Beltrami County, the Moose River Project is subject to state regulations, inspections, and enforcement. Despite being undesignated in terms of condition assessment, this dam serves its primary purpose of flood risk reduction effectively. The local government ownership and state jurisdiction ensure that the dam is well-maintained and operates in accordance with safety guidelines. With a drainage area of 14 square miles and a maximum discharge capacity of 500 cubic feet per second, the Moose River Project is a critical piece of infrastructure in safeguarding the community against potential flooding events.
