Aerial footage shows construction progress at Bois d'Arc Lake Reservoir
Fannin County, Texas - Bois d’Arc Lake is the first major reservoir to be built in Texas in nearly 30 years, a project led by the North Texas Municipal Water District. The lake, located northeast of Bonham in Texas� Fannin County, will provide the water needed to serve a growing population of 1.7 million North Texans. The reservoir’s two-mile-long and 90-foot-tall dam will create a lake capable of storing 367,609 acre-feet of water (120 billion gallons).
