John T. Montford Dam is named in honor of the Texas Senator who garnered state-wide support for this project. Construction of the dam began in the spring of 1991 and was completed in August, 1993.

The dam is 3,600 feet long, 1,000 feet wide at the base, 138 feet high, and contains 6½ million cubic yards of compacted soil, clay and soil-cement. Lake Alan Henry is named in honor of former Lubbock Mayor Alan Henry for his untiring efforts toward the goal of an additional water supply for the City. Situated 65 miles southeast of Lubbock in Garza County on the Double Mountain Fork of the Brazos River, the lake when full, covers 2,880 acres and contains approximately 40 billion gallons of water. This reservoir volume can be compared to the area within Lubbock's Loop 289 at a depth of four feet of water. Confined between the rocky sides of the river channel, the lake extends 11 miles upstream to provide 56 miles of shoreline, an average water depth of 40 feet, and may be up to 100 feet deep at the dam. The lake will collect water runoff from a 400 square mile watershed area, to provide an average of 23.3 million gallons of water per day for the City of Lubbock.

Texas Parks & Wildlife Department's Fisheries Division began stocking Lake Alan Henry in 1993 with fingerlings of several game fish species such as: Blue Catfish, Channel Catfish, Bluegill, Gizzard Shad, Crappie, Florida Largemouth Bass, and Smallmouth Bass.

The Fisheries Division will provide continual monitoring of fishing habitat development and fish populations in the lake. It is anticipated that the lake will also attract many species of waterfowl and other wildlife, offering bird watching and photographic opportunities.
