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 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.
