Mercury and selenium concentrations in fishes of the Upper Colorado River Basin, southwestern United States: A retrospective assessment. [PDF]

PLoS ONE, 2020
Mercury (Hg) and selenium (Se) are contaminants of concern for fish in the Upper Colorado River Basin (UCRB). We explored Hg and Se in fish tissues (2,324 individuals) collected over 50 years (1962-2011) from the UCRB.

Atmospheric Rivers and Snow Accumulation in the Upper Colorado River Basin

Geophysical Research Letters, 2021
We utilized a macroscale hydrology model in conjunction with an atmospheric river (AR) catalog to evaluate AR‐affected snow accumulation in the Upper Colorado River basin (UCRB) headwaters for water years 1951–2015. We find that there are on average 11.4

Database of surface water diversion sites and daily withdrawals for the Upper Colorado River Basin, 1980–2022 [PDF]

Scientific Data
The Colorado River drains about 8% of the conterminous United States, provides water for 40 million people, and is one of the most overallocated rivers in the world. As the upper Colorado River Basin (UCOL) contributes an estimated 92% of the total basin

Medieval drought in the upper Colorado River Basin [PDF]

Geophysical Research Letters, 2007
New tree‐ring records of ring‐width from remnant preserved wood are analyzed to extend the record of reconstructed annual flows of the Colorado River at Lee Ferry into the Medieval Climate Anomaly, when epic droughts are hypothesized from other paleoclimatic evidence to have affected various parts of western North America.

Climate change impacts on streamflow and subbasin-scale hydrology in the Upper Colorado River Basin. [PDF]

PLoS ONE, 2013
In the Upper Colorado River Basin (UCRB), the principal source of water in the southwestern U.S., demand exceeds supply in most years, and will likely continue to rise. While General Circulation Models (GCMs) project surface temperature warming by 3.5 to

Hydrologic response of groundwater and streamflow to natural and anthropogenic drivers of change in headwaters of the upper Colorado River basin during recent wet (1982–1999) and drought (2000–2022) conditions

Journal of Hydrology: Regional Studies
Study region: Headwaters of the upper Colorado River basin (UCOL), USA Study focus: Surface-water and groundwater numerical models incorporating water-use information were used to investigate changes in climate, water use, and simulated hydrologic ...

Revisiting the application of variable infiltration capacity (VIC) model in the Colorado River Basin using SMAP and GRACE [PDF]

Scientific Reports
The Colorado River Basin (CRB) is a crucial water supply source experiencing prolonged drought conditions. Hydrologic models of the CRB have historically relied on streamflow calibration alone, limiting confidence in their representation of spatially ...

Enhancing Monthly Streamflow Prediction Using Meteorological Factors and Machine Learning Models in the Upper Colorado River Basin

Hydrology
Streamflow prediction is crucial for planning future developments and safety measures along river basins, especially in the face of changing climate patterns. In this study, we utilized monthly streamflow data from the United States Bureau of Reclamation
