Industrial use of water in WyomingÆs Platte River Basin consists of approximately 75 percent groundwater use and 25 percent surface water use. The power generation sector is the largest permitted industrial water consumer in the Lower Laramie subbasin. The second largest subbasin water consumer, road and bridge construction and maintenance, is permitted to use only approximately 4 percent as much as the quantity of water that the power generation industry is permitted to use.
