Oregon Water Use Program

With the ever-increasing rate of utilization of and competition for water (particularly during periods of drought) accurate, current water-use information is of considerable value. This is particularly so in determining future water availability in hydrologically critical areas and for making sound resource-management decisions. For the Oregon Water Science Center, a viable water-use data-...
