Every Boat Ramp on Keyhole Reservoir

About Keyhole Reservoir

Keyhole Reservoir is a 9,400-acre irrigation reservoir in northeastern Wyoming, located near the iconic Devils Tower National Monument. The reservoir offers outstanding multi-species fishing with walleye as the headline attraction, producing fish in the 16- to 24-inch range with trophy specimens exceeding 8 pounds. Northern pike are aggressive and plentiful, with fish over 30 inches commonly caught in the weedy bays and along the marshy shoreline areas.

Keyhole State Park provides boat ramps, camping, and day-use facilities around the reservoir, and the views of Devils Tower rising above the Black Hills to the northwest add a uniquely Wyoming element to every fishing trip. Smallmouth bass have been established and provide exciting light-tackle action along the rocky points and gravel bars, while crappie and yellow perch offer excellent panfishing. Channel catfish are abundant and grow well in the reservoir's warm, productive waters. The combination of quality fishing, stunning scenery, and proximity to Devils Tower makes Keyhole Reservoir a must-visit destination for anglers exploring northeastern Wyoming and the Black Hills region.
