We estimated mean volumes of 38 trillion cubic feet (TCF) of undiscovered natural gas, 159 million barrels of natural gas liquid (MMBNGL), and no oil in accumulations of 0.5 million barrels (MMBO) or larger in this area.
We estimated mean technically-recoverable undiscovered continuous and conventional resources that total 495 million barrels of oil, 27.5 trillion cubic feet of natural gas, and 410 million barrels of natural gas liquids in this area.
Discussion and links to research for the multi-disciplinary investigation on the Norman Landfill located on alluvium associated with the Canadian River in central Oklahoma.
Describes a national reconnaissance study of reproductive health in two species of fish across the US. More than 2,200 common carp and 650 largemouth bass were collected at 119 rivers and streams.
Summarizes graphically the areas where water levels have dropped, and by how much, in this extensive underground water reservoir that covers several states in the mid-continent.
Locations for nine species of large constrictors, from published sources, along with monthly precipitation and average monthly temperature for those locations. Shapefiles for each snake species studied.
Freshwater withdrawal estimates for Oklahoma by source and category. Withdrawal data from ground water and surface water for domestic, commercial and agricultural use.
Methods to depict the connectedness of rock units across fault and fracture zones, allowing us to determine the distribution of geologic units, structural features, and other controlling factors, such as porosity and permeability.
Consistent, historic, and up-to-date ground-water data, such as water levels collected at wells and springs, are available from the USGS National Water Information System as graphs, tables, or files to download.
Estimates of change in major types of land use and land cover from 1973 to 2000 should help model potential future change as climate, population, public policy, and technology change.
Description and photos related to the Picher Mining District in Oklahoma, once a primary U.S. source of lead and zinc and now the largest superfund site in the U.S. with millions of cubic yards of mine tailings (locally known as "chat") remaining.
Consistent, real-time water data from streams, lakes, reservoirs, ground-water, and meteorological sites, are available from the USGS National Water Information System as graphs, tables, or files to download.
One of the greatest challenges for conserving grassland, prairie scrub, and shrub-steppe ecosystems is maintaining prairie dog populations across the landscape. Of the four species of prairie dogs found in the United States, the Utah prairie dog (Cynomys

Streamflow statistics and basin characteristics for most streams in specific US states using the Streamstats program. Data for areas can be selected from interactive maps and by an automated process. Includes a tutorial.
Consistent, historic, and up-to-date surface-water data, such as gage height (stage) and streamflow (discharge), collected at major rivers, lakes, and reservoirs, downloadable from the USGS National Water Information System as graphs, tables, or files.
Science issues in this area identified by USGS and its partners, including regional goals and objectives, threats and emerging issues, and information gaps
Explains the characteristics and history of this distinctive way of describing geographic position characteristic of the midwestern and western states of the US.
This updated subset of USGS streamgages for which the streamflow primarily reflects prevailing meteorological conditions for specified years, screened to exclude sites where human activity affects the natural flow of the watercourse.
We use moderate resolution satellite data to assess live fuel condition for estimating fire danger. Using 23 years of vegetation condition measurements, we are able to determine the relative greenness of wildland vegetation susceptible to burning.
