The National Petroleum Reserve-Alaska (NPRA) Legacy Data Archive contains geological and geophysical data collected during two extensive exploration programs, the first conducted by the U.S. Navy between 1944 and 1953 and a second conducted by the U.S. Geological Survey (USGS) from 1974 to 1982.

Interactive mapping of groundwater levels.

The Land Treatment Digital Library (LTDL) was created by the U.S. Geological Survey to catalog legacy land treatment information on Bureau of Land Management lands in the western United States. The LTDL currently houses thousands of treatments from BLM lands across 10 states.

The Western Migrations web application uses an interactive map to foster exploration of detailed migration routes, stopovers, and winter ranges across the West. Filter the data by species, state, specific herds, or land ownership, including Federal and Tribal lands, to focus on the areas and animals most relevant to your work or interests.

The Land Treatment Exploration Tool is designed for resource managers to use when planning land treatments. The tool provides useful summaries of environmental characteristics of planned treatment areas and facilitates adaptive management practices by comparing those characteristics to other similar treatments within a specified distance or area of interest. Provisional Software.

River DroughtCast delivers current streamflow drought conditions and weekly forecasts of streamflow drought at select streamgages with long-term, complete records across the lower 48 states (the conterminous U.S., or CONUS).

In both Native Hawaiian and Alaska Native traditions, birds play important roles in tracking seasons, signaling weather changes, guiding navigation, and locating food resources. Their movements and behaviors are read as part of an ongoing dialogue with the natural world.

The Humboldt Capture Query Tool (HCQT) is an interactive application that helps water managers, scientists, and public stakeholders explore how groundwater pumping affects streamflow and other water sources across the Humboldt River Basin.

The Geochemical Data Portal assembles, reformats, corrects, and archives data obtained from the geochemical analysis of geologic samples collected for USGS and Department of Energy studies.

This interactive web application allows you to explore, filter, and download subsets of the Energy Geochemistry Database (EGDB). The EGDB contains analytical data for samples collected by the Energy Resources Program (ERP) to develop an understanding of the physical and geochemical processes responsible for hydrocarbon formation.

The Central Valley has four hydrologic regions, from north to south: the Sacramento Valley, the Delta & Eastside Streams, the San Joaquin Basin, and the Tulare Basin. Water flows from Sacramento Valley, Tulare Basin, and the San Joaquin Basin, into the Delta & Eastside Streams through the Central Valley's only natural outlet, the Carquinez Strait, on its way to the Pacific Ocean.

The Central Valley Hydrologic Model version 2 (CVHM2) is an integrated surface–subsurface hydrologic model, representing the major components of the hydrologic system of California’s Central Valley. This new decision support tool is useful for testing water management strategies in California's Central Valley.
