Climate Change

Estimates of climate change impacts on Colorado River flows range from 10 percent by the end of the century to 40 percent by 2050. Below are sample outputs assuming a 20% reduction in flows by 2100. (All reservoir volumes used in the sample outputs are relative to operational volumes - the lowest point at which water can be released due to physical or operational constraints.)

Trace One (start year = 1910)
Trace One (2008 begins with 1910 flows)
Trace Two (start year = 1950)
Trace Two (2008 begins with 1950 flows)

Historic Flows

Estimates for the long-term average annual flow of the Colorado River over many centuries range from 13.0 to 14.7 million acre feet (maf). The Bureau of Reclamation forecasts future Colorado River flows will be 15.0 maf. CROSS allows you to use the steamflow of your choosing. Sample outputs here use a streamflow of 14.0 maf. (All reservoir volumes used in the sample outputs are relative to operational volumes - the lowest point at which water can be released due to physical or operational constraints.)
