The USGS Integrated Water Availability Assessments (IWAAs) are designed to be a multi-extent, stakeholder driven, near real-time census and seasonal prediction of water availability for both human and ecological uses at regional and national extents. As part of the IWAAs program, the National Water Availability Assessment (National IWAAS) is intended to provide a periodic interpretive assessment of past, current, and future water demands compared to available supplies of clean water. The assessment will consider many of the factors that can influence the availability of water suitable for human and ecosystem uses including climate variability and change, and socioeconomic drivers such as changes in population, land...
The Gap Analysis Project (GAP) is an element of the U.S. Geological Survey. GAP helps to implement the Department of the Interior’s goals of inventory, monitoring, research, and information transfer. GAP has three primary goals: Identify conservation gaps that help keep common species common; Provide conservation information to the public so that informed resource management decisions can be made; and Facilitate the application of GAP data and analysis to specific resource management activities. To implement these goals, GAP carries out the following objectives: Map the land cover of the United States Map predicted distributions of vertebrate species for the U.S. Map the location, ownership and stewardship of...
The AMMonitor community is a collaboration of remote wildlife monitoring projects whose media data (audio, photos, and video and their metadata) comprise a repository for use in (1) ongoing adaptive management and research of wildlife, and (2) the development of new predictive models, via machine learning, for the automated identification of target species from media. Each collaborating project uses the AMMonitor R package and database structure for pooling data under a unifying framework that meets high quality standards for rich metadata. Each project exists as a child-item of this ScienceBase community, containing metadata about the project itself. These project items contain media folders as children, which...
The Ecological Flows (Ecoflows) Program within the Water Mission Area (WMA) provides the data and science needed to develop and quantify relations between water availability and biological responses through improving the WMA’s ability to predict key ecological outcomes of human activities on the landscape. Program sub-objectives include: developing a comprehensive understanding of the interactions among aquatic ecosystems, hydrology, and hydrochemistry, developing and applying models to predict potential effects of changes in population, land use, climate, and management practices upon future water availability, and predicting the availability of impaired water resources and the effects of using these water sources...
This data release provides a monthly irrigation water use reanalysis for the period 2000-20 for all USGS Watershed Boundary Dataset of Subwatersheds (HUC12) in the conterminous United States (CONUS). Results include reference evapotranspiration (ETo), actual evapotranspiration (ETa), irrigated areas, consumptive use, and effective precipitation for each HUC12. ETo and ETa were estimated using the operational Simplified Surface Energy Balance (SSEBop, Senay and others, 2013; Senay and others, 2020) model executed in the OpenET (Melton and others, 2021) web-based application implemented in Google Earth Engine. Results provided by OpenET/SSEBop were summarized to hydrologic response units (HRUs) in the National Hydrologic...

In recent years, the USGS and partners have been integral in monitoring, analyzing, and modeling streamflow permanence. This community of practice includes key USGS scientists and partners who have been involved in the establishment and advancement of that science. The primary objective of this community is to provide an organized platform to document the activity and resources related to streamflow permanence. Additionally, we aim to facilitate more efficient collaboration among internal and external streamflow permanence experts.
Welcome to the U.S. Geological Survey (USGS) Alaska Science Center (ASC), headquartered in Anchorage, Alaska. At the ASC, all of the USGS Mission Area Programs are managed collectively with a vision to achieving an integrated landscape level understanding of the highly diverse and complex Alaskan and Arctic Ecosystems. The mission of the Alaska Science Center is to provide objective and timely data, information, and research findings about the earth and its flora and fauna to Federal, State, and local resource managers and the public to support sound decisions regarding natural resources, natural hazards, and ecosystems in Alaska and circumpolar regions.
These resources are a collection of formally released datasets and data products created or managed by the U.S. Geological Survey. The collection provides access to data and services to facilitate public data sharing, as well as to help establish linkages to associated publications and projects both within and outside of the bureau.
