Rose Lake, also known as Mill Pond, is a gravity dam located in Dalton, Minnesota, along the Pomme de Terre River. Constructed in 1919, this dam serves primarily for purposes other than flood control or hydropower generation. With a height of 22 feet and a length of 200 feet, Rose Lake has a storage capacity of 207 acre-feet and covers a surface area of 108 acres.

Managed by the Minnesota Department of Natural Resources, Rose Lake is regulated, permitted, inspected, and enforced by state agencies to ensure its structural integrity and safety. Despite its significant hazard potential, the dam is currently in satisfactory condition as of the last inspection in August 2017. The dam's emergency action plan status, risk assessment, and management measures are currently undetermined, highlighting the importance of ongoing monitoring and maintenance to mitigate potential risks and ensure the safety of the surrounding communities and the environment.

Water resource and climate enthusiasts can appreciate Rose Lake as a historic and essential infrastructure that contributes to the management of water resources in Otter Tail County, Minnesota. Its location along the Pomme de Terre River and its purpose as a local government-owned structure underscore its significance in the region's water management efforts. As climate change continues to impact water resources, the proper maintenance and monitoring of dams like Rose Lake become crucial in ensuring the resilience and safety of communities and ecosystems downstream.
