Filling the Gap Report Series: Colorado

Most of the population growth for the next 40 years in Colorado is expected to occur in the South Platte Basin and in the urban counties of the Arkansas Basin. The population in these areas is projected to grow by 70% from 2010 to 2050, and this growth will be the main driver for the increase of Colorado's water demand during the next four decades. The state of Colorado has projected that 85% of the population of the state (7.7 million Coloradans) will be living in these areas by 2050; and that an additional total water supply of 453,000 acre-feet (147.6 billion gallons) per year will be required to meet the water demands of the residents and industries of the South Platte Basin and the urban counties of the Arkansas Basin by 2050.

Western Resource Advocates, Trout Unlimited, and the Colorado Environmental Coalition recognize the importance of preparing for our water future. However, we are concerned that many traditional water supply strategies have resulted in adverse impacts to rivers and streams and their associated environmental, recreational, and economic values. Rather than continuing old patterns, 21st century water development must account for instream flow needs, minimize the adverse environmental impacts of water supply strategies, and even improve stream flows or other environmental conditions on streams that are already depleted. These new challenges require new ways of thinking and new tools.

The Filling the Gap Series provides a proactive approach to meeting the future water needs of Colorado while protecting the state's economy, environment, and exceptional quality of life. Below you may find additional information on the reports of the Filling the Gap Series, including snapshots of their respective water management portfolios, which would more than fill the projected needs for the communities of the South Platte Basin and the urban counties of the Arkansas Basin.
