Public meeting scheduled in Jamestown, N.D., on Pipestem Dam Safety Modification Study

Published Jan. 16, 2019
OMAHA, Neb. - The U.S. Army Corps of Engineers, Omaha District (Corps) will hold a public meeting on Wednesday January 16, 2019 to provide information on the Dam Safety Modification Study (DSMS) for Pipestem Dam in Stutsman County, North Dakota, which is located about four miles northwest of Jamestown, North Dakota. The DSMS is being performed to address dam safety risk related to the potential for erosion of the emergency spillway during spillway flow. The public meeting will be held at the Jamestown Area Chamber of Commerce, 120 2nd Street SE in Jamestown. The meeting will run from 6-8 p.m. with a brief presentation at 6:30 p.m. followed by an open house. During the open house, the public will have an opportunity to talk with Corps team members about the dam safety study.

The Corps will be preparing an Environmental Assessment (EA) to analyze modification of the emergency spillway. The intent of the project is to reduce the risk of spillway erosion without modifying the operation of the dam for water control or flood risk management. Potential spillway modifications include hardening the upstream end of the spillway to prevent erosion and modifying the downstream end of the spillway to prevent erosion and dissipate the energy of water exiting the spillway before it enters Pipestem Creek.

In accordance with the National Environmental Policy Act, we will be looking for comments in order to obtain your view regarding the proposed project, as well as your input on potential alternatives to address the risk of spillway erosion.
