Mormon settlers founded the area of Hyrum, which is located in Cache Valley. Hyrum is named after the brother of the founder of the Mormon Church. Before the dam was built in 1939, Mormon settlers had to dig a nine-mile canal from the Little Bear River for farm irrigation in Hyrum.

Years before the Mormon settlers arrived in the valley, General William H. Ashley stopped near what is now the edge of Hyrum Reservoir and cached $150,000 worth of furs, mostly beaver, in the winter of 1825-26. They were stored in a cave dug in a clay bank until they were retrieved the following summer. This history resulted in the French-Canadian name of Cache Valley and Cache County.

Hyrum State Park is a terrific year round fishing destination for bass, trout, perch, and bluegill. In the summer the park is an excellent place to participate in a variety of water sports. The park makes a great base camp for hikers, bikers, rock climbers, and auto tours.

Opened to the public as a state park in 1959.

Park Elevation – 4,700 feet
