Water availability on Colorado’s Western Slope is under increasing pressure and uncertainty from climate change, population growth, and ongoing negotiations.

“We’re seeing a shrinking resource, and one trend that is likely to continue to accelerate whether we have more precipitation or not … is the warming temperatures are going to drive less water available for human use,” said Andy Mueller, general manager of the Colorado River District. “The question is: Can we as a society come together and plan for that? We haven’t done a great job of doing that so far, but perhaps we can.”

He posed this question to a room full of water managers, agricultural producers, and elected officials in Grand Junction on Friday, Sept. 20, for the Colorado River District’s annual water seminar. This year’s seminar encouraged attendees to “meet the moment” and to find clarity, solutions, and opportunities amid water insecurity in the West. As the event kicked off, attendees were asked to share the biggest challenge facing water management in their community. Words like “drought,” “scarcity,” “lack,” “quantity,” “politics,” “knowledge,” “climate change,” and “agreement” dominated the responses from attendees…

With these negotiations underway in the basin, conflict is likely unless stakeholders begin working together, planning, and learning from past mistakes and challenges…This collaboration includes bringing more voices to the table, particularly those left out of historic water negotiations. Lorelai Cloud, vice chairman of the Southern Ute Indian Tribal Council and director for the Colorado Water Conservation Board, said the 30 Native American tribes in the Colorado River Basin are 100 years behind on the conversations after being left out of the initial compact negotiations and many of the subsequent discussions.

“New plot using the nClimGrid data, which is a better source than PRISM for long-term trends. Of course, the combined reservoir contents increase from last year, but the increase is less than 2011 and looks puny compared to the ‘hole’ in the reservoirs. The blue Loess lines subtly change. Last year those lines ended pointing downwards. This year they end flat-ish. 2023 temps were still above the 20th century average, although close. Another interesting aspect is that the 20C Mean and 21C Mean lines on the individual plots really don’t change much. Finally, the 2023 Natural Flows are almost exactly equal to 2019. (17.678 maf vs 17.672 maf). For all the hoopla about how this was record-setting year, the fact is that this year was significantly less than 2011 (20.159 maf) and no different than 2019” — Brad Udall
