Measuring over 21,000 feet in length, the Fort Peck Dam is among the largest hydraulically filled dams in the world today, spanning across the Missouri River and covering 3.5 miles. The dam is 250.5 feet high and has five turbines that generate 185,000 KW of power. The main purpose why the dam was built was not only to help control floods but also to help give people jobs. When the dam was built in 1936, more than 10,000 people were given jobs during a time of economic depression.

The name For Peck was derived from a trading post established by Col. Campbell K. Peck together with Commander E.H. Dufree in an area near the dam in 1867.

Today, visitors of the Fort Peck Lake in Montana are given the opportunity not just to view the dam but to involve in outdoor activities as well such as hunting and fishing.
