From some of my research it appears the reservoir was first proposed in the 1930's. However the original site was part of Zion National Park and was found to be illegal.

Construction on the Kolob Creek Dam was completed in the fall of 1956. The reservoir was dedicated on June 15th, 1957.

During the summer months of 2018, researchers from the Division of Wildlife Resources made a discovery at the reservoir. Three distinct fish – yellow perch, bluegill sunfish, and green sunfish – were identified. It was determined that these fish were unlawfully introduced into the ecosystem and were regarded as a potential menace to the native fish population inhabiting Kolob Reservoir. The water level was then lowered and treated with rotenone on October 15th and 16th. After the treatment tiger trout were introduced into the reservoir for the first time.
