Lake Alan Henry is a reservoir situated in the upper Brazos River Basin in the United States.

[3] Lake Alan Henry is located on the Double Mountain Fork Brazos River in West Texas.

[3] Operating at full capacity, Lake Alan Henry could potentially contain over 40 billion gallons of water.

[7] Currently, a consumption advisory is in place for certain species of fish found in the lake due to concerns of high levels of mercury.

[8] In the 1960s, the city of Lubbock moved forward with plans to create another water source for its growing population, and after years of soil studies and engineering research, the current location of the John T. Montford Dam was chosen as the closest and most suitable area for the structure and subsequent reservoir.
