New White Paper: Alternative Management Paradigms  for the Future of the Colorado and Green Rivers

New White Paper: Alternative Management Paradigms for the Future of the Colorado and Green Rivers

02/05/2021

This White Paper is designed to encourage wide-ranging and innovative thinking about how to sustainably manage the water supply, while simultaneously encouraging the negotiators of new agreements to consider their effects on ecosystems. The authors introd...

Partnership for Water Conservation and Mitigation

Partnership for Water Conservation and Mitigation

11/06/2020

Water conservation trickles down on two fronts—ecological and political issues surrounding the flow in the river, and what happens when water comes out at the end of the pipelines. Although CCRS tends to focus on the front end of water issues, we support ...

The Complex Task of Predicting how Temperature Changes will Affect Native and Non-native Fishes

The Complex Task of Predicting how Temperature Changes will Affect Native and Non-native Fishes

10/05/2020

Although one might assume that warming river temperatures downstream from dams might be good for native fishes, the reality is more complex. There are many nonnative species that do well in warm water and their increases can have negative impacts on nativ...

How well do we understand numbers in the Colorado River basin?

How well do we understand numbers in the Colorado River basin?

09/23/2020

Effective water-supply negotiation and river management are best served if Colorado River stakeholders are mindful of the precision and accuracy of the many components of the hydrologic cycle that affect the water supply of the Colorado River. As part of ...

New White Paper: The Future Hydrology of the Colorado River Basin

New White Paper: The Future Hydrology of the Colorado River Basin

09/17/2020

Long-range planning of the water supply provided by the Colorado River requires realistic assessments of the impact of a continuation of the current drought that began in 2000, the impact of potentially extreme future droughts, and the long-term and progr...

The Lake Powell Pipeline: Asking the Bigger Questions

09/01/2020

New on our Blog: "Simply put, the Upper Colorado River Basin is now caught in a vise. We have fixed commitments under the 1922 compact and a declining supply of water above Lee Ferry. Yet many are still operating under the illusion that the Upper Basin ha...

New Research: A Better Way to Measure Uncertainty with Aerial Photos

New Research: A Better Way to Measure Uncertainty with Aerial Photos

07/31/2020

River channels change in response to natural and human-caused fluctuations in streamflow and sediment supply. Predicting how the channel might change from alterations in streamflow and sediment supply is an important and challenging part of managing a riv...

Effective Renegotiation of the Guidelines for Management of the Colorado River Water Supply Necessitates a Wide Range of Scenarios of Future Water Use

Effective Renegotiation of the Guidelines for Management of the Colorado River Water Supply Necessitates a Wide Range of Scenarios of Future Water Use

06/15/2020

An essential question that drives discussion about the future of the Colorado River is, “How much water do we need?” The human body must have water to survive, and water is needed to grow crops, but the amount of water used by different societies varies g...

Science Moab: A Look at Paleo-Flood Hydrology

02/18/2020

The Colorado River Basin has experienced incredibly large flood events in the past. Present-day river deposits can be used to understand the size and timing of floods that have happened within the region. Listen to Dr. Vic Baker who studies what he calls ...

Scenarios Consistently Overestimate Consumptive Water Use in the Upper Colorado River Basin

Scenarios Consistently Overestimate Consumptive Water Use in the Upper Colorado River Basin

01/30/2020

Future consumptive water use is difficult to predict because underlying factors that influence consumptive use—future population growth, irrigation technology and practices, climate, agricultural commodity prices and other factors—are individually difficu...
