From The Mountain Mail (Joe Stone):
Six reservoir sites received gauges to monitor alpine water and weather conditions. Nine tributary stream gauge sites were constructed above strategic diversion points (historic controlling calls) in Chaffee, Custer, and Fremont counties.
Colorado Water Conservation Board’s annual report, “Colorado’s Water Supply Future,” said, “More than 500,000 downstream Colorado residents are affected by available supplies of Upper Arkansas River Valley water.” In addition, the report summarized a study of surface water and groundwater interaction conducted by the conservancy district and the U.S. Geological Survey.
