Colorado River Basin Focus Area Study: Water Use

Water-use data were compiled as annual total withdrawals by source and aggregated to 8-digit Hydrologic Unit Code watersheds from 1985 to 2010 in five year intervals. The new compilation allows for an evaluation of water-use trends in the Colorado River Basin and the effect of use on the water budget.

Colorado River Basin Focus Area Study: Groundwater discharge to streams

Methods were developed in the CRB FAS to estimate groundwater discharge to streams in the upper Colorado River Basin (UCBR) using in-stream water-quality data. Results indicate groundwater discharge to streams contributes an average of 48 percent of total streamflow in the UCRB.

Delaware River Basin Focus Area Study: Process-Based Streamflow Modeling

The Water Availability Tool for Environmental Resources provides a decision support system to examine different land-cover forecasts and climate projections using physical aspects of the basin that will remain unchanged, like topography and soil properties, to estimate streamflow for ungaged streams.

Delaware River Basin Focus Area Study: Statistical Streamflow Modeling

The Delaware River Basin Streamflow Estimator Tool (DRB-SET) uses historical records of streamflow to estimate daily mean streamflow at any stream location within the Delaware River Basin for the period 1960-2010, incorporating basin characteristics such as drainage size, soil, geology, and seasonal precipitation.

Delaware River Basin Focus Area Study: Water Use

Water-use data were compiled or estimated for 8-digit and 12-digit Hydrologic Unit Code watersheds for 2010. Water withdrawal, interbasin transfers, return flow, and hydroelectric power generation release data were compiled for 11 water-use categories.

The National Water-Use Science Project

The U.S. Geological Survey's National Water-Use Science Project (formerly the National Water-Use Information Program) is responsible for compiling and disseminating the nation's water-use data. Established by USGS in 1978, the USGS National Water-Use Science Project built on the legacy of the Estimated Use of Water in the United States report series, begun in 1950 and produced...

The Story of the USGS Research Vessel (R/V) Polaris

For the past 50 years, the USGS has been conducting research in the San Francisco Bay and Delta, California and beyond. This research would not have been possible without the Research Vessel (R/V) Polaris. Many scientists who have been fortunate to work on the Polaris have come and gone, but the Polaris sailed from the South San Francisco Bay continuously from 1968...
