Two Rivers, also known as Hallock Dam, is a gravity dam located in Kittson County, Minnesota, along the Two Rivers South Branch. Built in 1938 by the Works Progress Administration, this structure stands at a height of 19 feet and has a normal storage capacity of 125 acre-feet to help mitigate flood risks in the area. The dam is regulated by the Minnesota Department of Natural Resources and undergoes regular inspections to ensure its satisfactory condition.

With a low hazard potential and a moderate risk assessment rating, Two Rivers plays a crucial role in flood risk reduction for the surrounding community. The dam's uncontrolled spillway, with a width of 45 feet, allows for a maximum discharge of 1900 cubic feet per second, helping to manage water levels during periods of heavy rainfall. Despite its age, Two Rivers remains structurally sound and continues to serve its primary purpose effectively.

As a vital piece of infrastructure in the region, Two Rivers highlights the importance of proper water resource management and climate resilience. Its presence not only protects the local area from potential flooding but also underscores the need for ongoing maintenance and monitoring of dams to ensure their continued functionality in the face of changing environmental conditions.
