A bill that opponents say would undermine senior water rights first died, then was resurrected and gained preliminary approval in the House on Tuesday, the Pueblo Chieftain reports. Sponsored in the House by Rep. Kathleen Curry, U-Gunnison, SB52 seeks to honor already permitted wells in the event that the Colorado Ground Water Commission redraws boundaries of the state’s eight existing designated groundwater basins. Designated groundwater basins generally are considered nontributary, or at least not adjacent to major streams and rivers. They may include municipal, industrial and agricultural uses.
