Reservoir Levels Weather Hydrology

Hyrum Reservoir is located in Cache County in Utah and was constructed in 1935 as part of the Civilian Conservation Corps program. The reservoir has a capacity of 14,000 acre-feet and is primarily used for irrigation purposes in the Cache Valley. The hydrology of the reservoir is primarily fed by the Little Bear River, which is a tributary of the Bear River. The Little Bear River is a snowmelt-dominated stream and the reservoir receives a significant amount of its water supply from snowpack in the surrounding mountains. The reservoir is also popular for recreational activities such as fishing, boating, and camping, and is stocked with rainbow trout, bluegill, and channel catfish. Additionally, the reservoir supports several agricultural activities, including the cultivation of hay, barley, and corn.
