Low Flow Study Images
May 1, 2014

As part of their mission to protect public health and aquatic ecosystems, Alabama state agencies need accurate and representative streamflow statistics to establish realistic and applicable criteria for both water quality and water quantity (fig. 1). Historically, low-flow statistics, such as the annual minimum 7-day average flow that likely will occur, on average, once every 10 years (7Q10),...

Development along shoreline of Coeur d'Alene Lake
January 1, 2014

STATUS: Completed

Development around Coeur d'Alene Lake has accelerated over the past 25 years. Commercial and residential development adjacent to the lake plus demands for irrigation, recreation, and hydropower raise concerns about the potential for declining lake levels.

A comprehensive lake water budget helps resource managers determine the possible effects of growth on...

STATUS: Completed

The mining district in the South Fork Coeur d’Alene River valley was among the Nation’s largest producers of silver, lead, zinc, and other metals from the 1880s to the 1980s. These activities have produced large quantities of waste material that contain environmentally hazardous contaminants such as cadmium, lead, and zinc. Much of this material has been...

Black Warrior River Map
September 22, 2012

Static flood-inundation map libraries consist of maps that have been created in advance of a flood that are ready to be served through the Internet. Each library consists of a set of flood extent and depth maps developed for predetermined stream stage intervals (for example, a map for each one foot of stage). A user can view real-time or forecast stage data from a USGS streamgage or National...

StreamStats is a Web-based tool that provides streamflow statistics, drainage-basin characteristics, and other information for USGS streamgaging stations and for user-selected ungaged sites on streams. When users select the location of a streamgaging station, StreamStats provides previously published information from a database. When users select a site on an ungaged stream, StreamStats will...

Terrestrial Light Detection and Ranging (T-LiDAR) Technology
September 22, 2011

T-LiDAR technology utilizes reflected laser pulses sent from a tripod-mounted scanning instrument to determine distances to targets of interest. The resulting dataset is a 3 dimensional model or "point cloud" of millions of XYZ data points, spaced only a few millimeters apart. This highly detailed dataset is used by USGS scientists to create topographic models, make detailed...

Various environmental groups in Alabama are concerned that the use of culverts at highway crossings to convey stream flows has detrimental effects on the natural conditions of streams. Specifically, some groups are concerned that changes in stream geomorphology, sediment concentrations, and associated turbidity adversely impact the benthic macroinvertebrate community when culverts are...

In 2002, the Davis Pond Freshwater Diversion began diverting up to 10,000 cfs of Mississippi River water into the waters surrounding the Barataria Preserve of the Jean Lafitte National Historical Park and Preserve. Previously, precipitation, local surface-water runoff, and occasional marine intrusion largely determined quality of surface and marsh porewaters at the Preserve. The new influx of...

A dynamic leaf gas-exchange strategy is conserved in woody plants under changing ambient CO2: evidence from carbon isotope discrimination in paleo and CO2 enrichment studies

Rising atmospheric [CO2], ca, is expected to affect stomatal regulation of leaf gas-exchange of woody plants, thus influencing energy fluxes as well as carbon (C), water, and nutrient cycling of forests. Researchers have proposed various strategies for stomatal regulation of leaf gas-exchange that include maintaining a constant leaf internal [CO2...
