Texans need water to drink, to bathe, to wash their clothes and, yes, to fill their pools. Accordingly, water utilities are working to finish two big Northeast Texas lake projects: Bois dā Arc Lake and Lake Ralph Hall. The Bois dā Arc Lake project ā the first reservoir built in Texas in 30 years ā is filling with water and the North Texas Municipal Water District, which has the rights to that massive project, says it will open soon to the public to enjoy the myriad recreational activities it will provide.
