Cornish Flowage, located in Aitkin, Minnesota, is a state-regulated dam completed in 1976 for the primary purpose of flood risk reduction. Managed by the Minnesota Department of Natural Resources, this rockfill dam stands at a height of 8 feet with a structural height of 9 feet and a length of 38 feet. With a storage capacity of 2000 acre-feet and a surface area of 300 acres, it plays a crucial role in controlling the flow of the Savannah River-TR.

The dam's condition is assessed as fair with a low hazard potential, and it undergoes inspections every 8 years to ensure its safety and integrity. The surrounding area benefits from its flood protection measures, with a maximum discharge capacity of 30 cubic feet per second. Despite its modest size and capacity, Cornish Flowage serves as a vital infrastructure for water resource management in the region, contributing to the overall resilience of the community against potential flooding events. Enthusiasts of water resources and climate would find this dam's design and purpose intriguing, highlighting the intersection of engineering, environmental conservation, and disaster risk reduction.
