Fort Peck Flow Test Information



The U.S. Army Corps of Engineers has been operating Fort Peck Dam since 1940. Stretching across the upper Missouri River in northeastern Montana, it is the furthest upstream of six dam reservoir projects built on the mainstem of the upper Missouri River.

In accordance with the 2018 biological opinion and as required under the Endangered Species Act for operation of the Missouri River Mainstem Reservoir System, the USACE will implement a test flow starting April 26, 2024, with an expected completion of September 1, 2024.

A test flow allows the USACE to evaluate whether alternative flow scenarios can promote the growth and survival of pallid sturgeon to its free-swimming juvenile stage while ensuring that impacts to the eight authorized purposes are avoided or minimized to the extent possible.

Human life and safety are a top priority for the USACE, so the test flow will be highly monitored and if conditions are deemed unsafe the test will be cancelled or stopped immediately.
