History
Although it was in the works for many years, it wasn't until 1985 that the Texas Water Commission granted permission to build the reservoir. At first, it was to be that this newly constructed reservoir be named Stacy settlement; however, it was finally decided that it was to be named after the water district's general manager, O.H. Ivie. The construction of the dam took place in May of 1987 and was finished in March of 1990. The dam is a rolled embankment of 15,950 feet in length, and 148 feet of maximum height.
