Managing Colorado River risk [PDF]

open access: yesScience, 2021
In the 1920s, E. C. LaRue, a hydrologist at the United States Geological Survey, did an analysis of the Colorado River Basin that revealed the river could not reliably meet future water demands. No one heeded his warning. One hundred years later, water flow through the Colorado River is down by 20% and the basin's Lake Powell and Lake Mead—the nation's

Recovery or continued resuscitation? A clinical diagnosis of Colorado River sub-basin recovery programs

open access: yesEcology and Society, 2023
With a particular emphasis on the Upper Colorado River Endangered Fish Recovery Program (UCR-EFRP) and Lower Colorado River Multi-Species Conservation Program (LCR-MSCP), we analyze, for each program, four system properties that contribute to resilience:

Development of streamflow projections under changing climate conditions over Colorado River basin headwaters [PDF]

open access: yesHydrology and Earth System Sciences, 2011
The current drought over the Colorado River Basin has raised concerns that the US Department of the Interior, Bureau of Reclamation (Reclamation) may impose water shortages over the lower portion of the basin for the first time in history. The guidelines

Institutional levels of water management in the Colorado River basin region: A macro-historical geographic review

open access: yesFrontiers in Water, 2023
Complex water-stressed basins like the Colorado River in North America have multiple institutional levels of water management. Each institutional level is characterized by rules, organizations, and spatial jurisdictions that developed over decades to ...

The impact of bedrock meander cutoffs on 50 kyr scale incision rates, San Juan River, Utah [PDF]

open access: yesEarth Surface Dynamics
Incision rates of major rivers may reflect the effects of drainage reorganization, hillslope processes, tectonic uplift, climate, the properties of rocks into which rivers incise, and other autogenic processes.

Of travertine and time: otolith chemistry and microstructure detect provenance and demography of endangered humpback chub in Grand Canyon, USA. [PDF]

open access: yesPLoS ONE, 2013
We developed a geochemical atlas of the Colorado River in Grand Canyon and in its tributary, the Little Colorado River, and used it to identify provenance and habitat use by Federally Endangered humpback chub, Gila cypha.

Incision history of Glenwood Canyon, Colorado, USA, from the uranium-series analyses of water-table speleothems

open access: yesInternational Journal of Speleology, 2013
Uranium-series analyses of water-table-type speleothems from Glenwood Cavern and “cavelets” near the town of Glenwood Springs, Colorado, USA, yield incision rates of the Colorado River in Glenwood Canyon for the last ~1.4 My.

Growth rates and scales of sand banks in the Colorado River Delta

open access: yesCiencias Marinas, 1999
A linear stability analysis was carried out to investigate the sand bank formation in the Colorado River Delta. A truncated solution of the vorticity equation was included in the bottom evolution equation in order to evaluate the initial growth rates of
