Welcome to our Fort Peck Lake Home Page

Fort Peck Lake is the largest lake in Montana measuring 134 miles long and it has 1520 miles of shoreline with a maximum depth of 220 feet.

This lake is known for its excellent walleye fishery, however, there are so many species of fish that you can catch here.  Salmon, lake trout, northern pike and smallmouth bass are all here in good enough numbers to fish for them and to expect to be able to catch some fish.  Crappie and catfish are here too.
