White River Bioenergetics
The White River Basin is located in western Washington and drains an area of about 500 square miles. Rivers in the White River Basin are fed by melt water from glaciers on Mt. Rainier, runoff from snowmelt and rain, and groundwater discharge. Beginning in the early to mid-twentieth century, the White River from river mile (RM) 9 to its confluence with the Puyallup River was extensively...
RCMAP - Gunnison River at the Hartland Dam near Delta, Colorado
The U.S. Geological Survey was engaged in a program to monitor and assess the long-term geomorphic behavior of selected river and stream reaches that previously had undergone some physical modification. These modifications included natural channel adjustments to floods as well as intentional channel reconfigurations to alter the function or appearance of a river reach.
The Hartland...
Fish Slam 2014
On November 20, 2014, eight teams of fishery biologists from the U.S. Geological Survey (USGS), U.S. Fish and Wildlife Service (USFWS), Florida Fish and Wildlife Conservation Commission (FWC), U.S. National Park Service (NPS), and Florida International University (FIU) gathered for a one-day sampling event to collect non-native fishes from canals, ponds and ditches in Miami-Dade County, FL....
Arsenic in Minnesota Groundwater
U.S. Geological Survey (USGS) and Minnesota Department of Health (MDH) scientists are assessing the distribution of arsenic in groundwater in Minnesota. Naturally occurring arsenic is common in groundwater in Minnesota. About 15 percent of drinking water wells statewide have arsenic concentrations that exceed the ...
Estimating Peak Streamflow Per Square Mile in Virginia’s Urban Basins
Models are presented that describe Virginia urban area annual peak streamflow per square mile based on basin percent urban area and basin drainage area.
Shenandoah River Instream Flow Studies
As urban and rural growth continues, competition for clean water expands into stream areas previously capable of meeting local water-use demands. Conflicts among instream and offstream users of streamflow increase as flows decrease. This research enhances understanding of summer low-flow conditions in the North Fork, South Fork, and Shenandoah Rivers, relating water availability to physical...
Low-Flow Characteristics of Virginia Streams
Understanding low flows in Virginia streams is essential to sound management of our water resources and associated riparian and watershed ecosystems. Meaningful characterizations of the magnitude, frequency, and duration of low flows provide valuable insights into the dynamics, variability, and flux associated with water movement through these unique stream systems. Improved estimates of low...
Virginia Flood Investigations
An important part of the Virginia Department of Transportation's missions is the safe maintenance, design, and constructions of bridges that cross-waterways and wetlands in the State. The data collected by USGS in conjunction with this project is a vital element of the overall task and mission of the Virginia Department of Transportation.
Peak-Flow Characteristics of Virginia Streams
Economic growth, and the development, management, and protection of Virginia’s natural resources require anticipating peak stream flows and changes in peak stream flows over time. Extensive hydraulic analysis and smart design are needed to limit the environmental impacts of buildings, pavements, highways, and bridges. Effective design and placement of structures built near streams and on flood...
Validation of Monthly-Mean Streamflow Equations
The U.S. Geological Survey, in cooperation with the Colorado Water Conservation Board, evaluated the predictive uncertainty of mean-monthly streamflow-regression equations representative of natural streamflow conditions in Colorado. This study evaluates the predictive uncertainty of mean-monthly streamflow-regression equations developed in a 2009 U.S. Geological Survey study using streamflow...
North American Bat Data Integration
The purpose of this project was to integrate the Bat Banding Program data (1932-1972) and the U.S. and Canada diagnostic data for white-nose syndrome with the USGS Bat Population Data (BPD) Project and provide the bat research community with secure, role-based access to these previously unavailable datasets. The objectives of this project were to: 1) integrate WNS diagnostic data into the BPD...
Mobile River Basin Study Design
The Mobile River Basin study is one of several NAWQA studies that began in Federal fiscal year 1997 (October 1996). Study planning and design, and analysis of existing data will be done during the first 2 years, which is consistent with all NAWQA studies. After the 2-year planning period, surface- and ground-water and biological data will be collected intensively for 3 years during a high-...
