Most recent water year data may be provisional. Years with incomplete gauge data have been omitted. Annual runoff totals are in units of 1000 Acre-Feet. Graphs are interactive, hovering over data will show the runoff values. Colorado Water Supply Outlook The Natural Resource Conservation Service water supply outlook, as of May 1, 2021, contains the following estimates of runoff for the May through July 2021 period at the following gauges (Note: Not all gauges shown for historical runoff are forecasted, in which case a representative gauge from the outlook report was chosen): Division River May - July Forecasted Runoff (1000 AF) % of 30 yr avg 1 South Platte River at South Platte 119 76% 2 Arkansas River above Pueblo 230 70% 3 Rio Grande River at Thirty Mile Bridge 64 60% 4 Gunnison River near Grand Junction 480 38% 5 Colorado River near Dotsero 675 53% 6 Yampa River near Maybell 325 41% 7 Animas River at Durango 150 41% LEARN MORE ABOUT US HISTORY CULTURE MEMORIAL SCHOLARSHIP COLORADO HISTORICAL ANNUAL RUNOFF CLICK HERE TO VIEW QUESTIONS?

BLOG ABOUT US OUR EXPERTS SERVICES PROJECTS CONTACT US WATERSHED PLANNING Facebook Twitter Share LRE provides watershed planning services in a number of Colorado basins, assisting with the development of watershed plans, conducting investigations to identify and target key pollutant sources, and recommending management solutions for parameters including nutrients, temperature, and metals. We bring together diverse groups, including both governmental and other public and private stakeholders, to collaborate in problem identification and development of watershed-level solutions. This includes compilation of historical water quality, biological, spatial and drainage infrastructure information, data analysis to identify stressors and pollutant loading sources and understand what is happening in the watershed, and identification of management strategies and plans for water quality improvement measures. We merge this expertise with our in-depth water supply planning experience, including in-depth knowledge of Colorado water rights/water law, hydrologic analysis, development of augmentation plan accounting, engineering support for water rights changes of use and filing for new water rights, consumptive use modeling, and supply optimization.
