The reservoir was impounded by the creation of Robert Lee Dam in 1969, with the support of the Upper Colorado River Authority, to provide a reliable water supply for Robert Lee and the surrounding communities in Coke County.

Robert Lee Dam is managed by the Colorado River Municipal Water District.

Severe drought conditions and record summer high temperatures in the area caused the Colorado River Municipal Water District to stop any further water withdrawals from Midland, Texas and surrounding communities.
