As a historic drought grips Colorado, tensions between residents are rising sharply, turning ordinary suburban streets into battlegrounds over lawn water use. Record hot temperatures compounded by a winter of below-average snowfall have pushed the state into severe water stress this summer. More than 4,000 residents have reported neighbors for violating those restrictions this summer, according to the utility, triggering widespread local debate. State climatologist and Colorado Climate Center director Russ Schumacher delivered a stark assessment at a recent briefing for the state’s drought task force, outlining just how severe conditions have become. More than 90 percent of Colorado remains classified as being in a drought condition, according to Schumacher, with no immediate signs of meaningful relief on the horizon.
