A Senate Energy and Natural Resources subcommittee will focus this week on federal water infrastructure, as it reviews a host of bills addressing the Colorado River Basin and other waterways. The Subcommittee on Water and Power will meet Wednesday on 16 separate bills and hear testimony from Bureau of Reclamation Commissioner Camille Calimlim Touton. A half-dozen of the measures on tap are related to the Colorado River, which supports some 40 million individuals across seven Western states.
