From its tributaries in the headwater high-country of the Blue River Basin to the Gulf of California, the Colorado River system is under pressure. Prolonged drought, climate change, and growth have sparked interstate negotiations, litigation, and increasing competition over a limited supply.
Understanding what is happening locally—and how it connects to the larger Colorado River system—is an important first step in understanding the necessity for responsible water use and management.
FROM SNOWPACK TO THE SEA: One Connected River System
Drought is being felt right here in the Blue River Watershed. Extremely low streamflows have prompted local communities to implement water restrictions. The lack of supply has forced managers to draw down reservoirs and seek out alternative sources.
Drought and climate change are also impacting much loved recreation—from shorter ski seasons to less opportunity for boating, fishing, and camping due to low water levels and streamflows.
The Blue River Watershed is a critical part of Colorado's interconnected water-supply system. Dillon Reservoir is a major component of the system that moves water from the Western Slope to the Front Range through transbasin diversions, while Green Mountain Reservoir provides important storage for Western Slope water users, including the Historic Users Pool. Water originating in the Blue River Basin supports both Western Slope and Front Range communities.
Drought in the headwaters has systemwide impacts—from headwater users and senior water-right holders, to those with junior rights who may face reduced supplies, communities and ecosystems that depend on return flows, and downstream users trying to fill their reservoirs.

The Blue River is a headwaters tributary of the Colorado River, connecting local water conditions to a river system that spans seven U.S. states and Mexico. Water originating in the Blue River ultimately becomes part of the Colorado River's supply for downstream communities, agriculture, ecosystems, and economies.
Prolonged drought, climate change, and growth are putting increasing pressure on the basin's limited water supplies, making the management of water in headwater watersheds like the Blue River increasingly consequential.
