Published July 2, 2024

ST. PAUL, Minn. – The U.S. Army Corps of Engineers, St. Paul District, is seeking comments on the draft Environmental Assessment, or EA, for the Orwell Dam maintenance project in Otter Tail County, Minnesota.

To complete this maintenance, Orwell Lake will drawdown in early fall and the stilling basin will be dewatered. A stilling basin is a structure that reduces the speed and turbulence of water before it continues downstream.

A final determination on the draft EA will be made following a 30-day public review period. A copy of the EA can be viewed and downloaded from the St. Paul District website at: The Corps is conducting a review of the environmental effects in accordance with the National Environment Policy Act.

All comments received will be made available to the public to include the possibility of being posted on a publicly accessible website. Individuals are requested not to include personal privacy information, such as home addresses or home phone numbers, in their comments, unless they do not object to such information being made available to the public.
