This map layer consists of federally owned or administered lands of the United States, Puerto Rico, and the U.S. Virgin Islands. Only areas of 640 acres or more are included. There may be private inholdings within the boundaries of Federal lands in this map layer. This is a revised version of the December 2005 map layer.

This map layer shows areal and linear water features of the United States, Puerto Rico, and the U.S. Virgin Islands. The original file was produced by joining the individual State hydrography layers from the 1:2,000,000- scale Digital Line Graph (DLG) data produced by the USGS. This map layer was formerly distributed as Hydrography Features of the United States. This is a revised version of the January 2003 map layer.

This website offers results from the project “Impacts of climate change on ecology and habitats of waterbirds”, which evaluates projected impacts of climate, urbanization, and water management scenarios on ecology and habitats of waterfowl and other waterbirds in the Central Valley of California.The Central Valley (CVCA) of California contains some of the most important habitats for waterfowl, shorebirds, and other waterbirds in North America. Most waterbird habitats in the CVCA which include wetlands, flooded rice fields, and other agricultural lands, rely on managed surface water supplies stored in reservoirs and delivered via a complex, interconnected system to a wide array of competing water users. Downscaled...

This publication updates previous fault maps of Oregon as a contribution to the larger U.S. Geological Survey effort to produce digital maps of active faults in the Pacific Northwest region. The new map is derived from the 1992 fault map of Pezzopane, Nakata, and Weldon that has seen wide distribution and has been reproduced in essentially all subsequent compilations of active faults of Oregon. This publication provides a substantial update of known active or suspected active faults east of the Cascades. Improvements in the new map include (1) many newly recognized active faults, (2) a linked ArcInfo map and reference database, (3) more precise locations for previously recognized faults on shaded relief quadrangles...

In this website, Colorado River Streamflow: A Paleo Perspective, we will assess the gaged record of Colorado River streamflow in the context of multi-century flow reconstructions from tree rings. We will describe the Colorado River system and its management, then the century-long gaged record of flow, and then the use of tree rings to extend, or reconstruct, the gaged record 400 years or more into the past, providing a more complete picture of past flow variability. We will take a closer look at the most recent streamflow reconstructions for Lees Ferry, and how they compare with previous reconstructions.

The Bureau of Reclamation's Lower Colorado Region serves as the "water master" for the last 688 miles of the Colorado River within the United States on behalf of the Secretary of the Interior. We manage the River and its reservoirs to meet water and power delivery obligations, protect endangered species and native habitat, enhance outdoor recreation opportunities, and provide flood control. The Region also maintains Hoover, Davis and Parker Dams, annually measures and accounts for the water's use, and maintains the river channel and protective levees. The Lower Colorado Region covers an area of nearly 202,000 square miles, and encompasses parts of five states that contribute water to or draw water from...

The fundamental geologic unit used in the 1995 National Oil and Gas Assessment was the play, which is defined as a set of known or postulated oil and or gas accumulations sharing similar geologic, geographic, and temporal properties, such as source rock, migration pathways, timing, trapping mechanism, and hydrocarbon type. The geographic limit of each play was defined and mapped by the geologist responsible for each province. The play boundaries were defined geologically as the limits of the geologic elements that define the play, such as the limits of the reservoir rock, geologic structures, source rock, and seal lithologies. The only exceptions to this are plays that border the Federal-State water boundary. In...

Cell maps for each oil and gas play were created by the USGS as a method for illustrating the degree of exploration, type of production, and distribution of production in a play or province. Each cell represents a quarter-mile square of the land surface, and the cells are coded to represent whether the wells included within the cell are predominantly oil-producing, gas-producing, both oil and gas-producing, or dry. The well information was initially retrieved from the Petroleum Information (PI) Well History Control System (WHCS), which is a proprietary, commercial database containing information for most oil and gas wells in the U.S. Cells were developed as a graphic solution to overcome the problem of displaying...

SWWA26_750UTM is a digital bathymetric surface grid of the seafloor off the coast of Southwest Washington and Northwest Oregon. Grid cell spacing is 750m and the projection is UTM Zone 10. The surface was produced by gridding National Ocean Service (NOS) Hydrographic Surveys collected between 1926 and 1928. This work includes the most recent bathymetric data available on a regional scale over the inner to middle continental shelf off the coast of Washington. The results represent the best available estimate of the seafloor morphology for the time period circa 1926.

This dataset contains the combination of geology data (geologic units, faults, folds, and dikes) from 6 1;100,000 scale digital coverages in eastern Washington (Chewelah, Colville, Omak, Oroville, Nespelem, Republic). The data was converted to an Arc grid in ArcView using the Spatial Analyst extension.

This preliminary experimental lithogeochemical map shows the distribution of rock types in the Virginia and Maryland parts of the Chesapeake Bay watershed. The map was produced digitally by classifying geologic-map units according to composition, mineralogy, and texture; rather than by age and stratigraphic relationships as shown on traditional geologic maps. This map differs from most lithologic maps in that the lithogeochemical unit classification distinguishes those rock units having key water-reactive minerals that may induce acid neutralization, or reduction, of hosted water at the weathering interface. The validity of these rock units, however, is independent of water chemistry, because the rock units are...

The geologic map was created in GSMAP at Socorro, New Mexico by Orin Anderson and Glen Jones and published as the Geologic Map of New Mexico 1:500,000 in GSMAP format in 1994. This graphic file was converted to ARC/INFO format by Greb Green and GlenJones and released as the Geologic Map of New Mexico in ARC/INFO format in 1997.

The mining claim density data of federal lands in Oregon are combined with the digital Oregon Public Land Survey (PLS) to create a digital map of the density of mine claims in Open-File Report 99-541. The mining claim density data of federal lands in Oregon was one of 13 western states released in Open-File Report 99-325. The database for Oregon was converted to an Arc/Info file and connected with the PLS by an Arc/Info relate. As stated in OF 99-325, "These mining claim density databases were created from data obtained in March 1997, from the Mining Claim Recordation System (MCRS) of the Bureau of Land Management. These databases provide mining claim density information in a tabular form. They quantify the status...
