Chippewa, also known as Tamarack Lakes, is a Federal-owned dam located in Becker, Minnesota, along the Otter Tail River. Built in 1930 by the US Fish and Wildlife Service, this Earth dam stands at a height of 12 feet and spans 85 feet in length. With a storage capacity of 7,650 acre-feet, it serves multiple purposes, including flood control and water supply for the surrounding area.

Despite its age, Chippewa has a low hazard potential and has not been rated for its condition assessment. The dam has not undergone any recent modifications and does not fall under state regulation or inspection. While the dam does not have an Emergency Action Plan prepared, it is still considered to meet safety guidelines. Chippewa plays a crucial role in managing water resources and protecting the local community from potential flooding events, highlighting the importance of maintaining and monitoring such infrastructure for the long-term sustainability of our water systems.
