Last week the Uncompahgre Valley Water Users Assoc. has placed a call on the Upper Uncompahgre because of low water levels in the area. The assoc. operates the Montrose and Delta Canal and that directly affects the city of Ouray as well. In addition to Ouray, other water users like Tri County Water Conservancy District are also affected and that will affect the water in Ridgway Reservoir which must now release its inflow downstream while the call is in effect. Only once in the recent past has Ouray’s water been subject to call. That was during the devastating water year of 2002.
