These datasets are created during the irrigation reanalysis workflow (irrigation_reanalysis.zip). The actet_openet.cbh, potet_openet.cbh, and dyn_ag_frac.param area created during step one of the workflow when converting daily OpenET/SSEBop results into input for the NHM. The nhm_2000_2020_ag_irrigation_add.csv, and nhm_2000_2020_ag_irrigation_add_vol.csv area estimated daily results output by the NHM.

Since 2005, the U.S. Geological Survey - Great Lakes Science Center's Lake Erie Biological Station (LEBS) has participated in a collaborative, multiagency effort to assess pelagic prey fish populations in the western (WB), central (CB), and eastern (EB) basins of Lake Erie through a combination of hydroacoustic and midwater trawl sampling. Assessing lake-wide distribution and abundance of pelagic prey species over time facilitates evaluation of large-scale drivers of fish production while also considering food-web dynamics at a smaller sub-basin scale. Information from this survey will support decision making within an ecosystem-based fishery management framework. In support of binational Great Lakes fishery management,...

In August 2017, the U.S. Geological Survey acquired high-resolution P- and S-wave seismic data near six Southern California Seismic Network (SCSN) recording stations in southern California: CI.OLI Olinda; CI.SRN Serrano; CI.MUR Murrieta; CI.LCG La Cienega; CI.RUS Rush; and CI.STC Santa Clara (Figure 1). These strong-motion recording stations are located inside Southern California Edison electrical substations, critical infrastructures that provide essential services to millions of customers. The primary goals of the seismic survey were to understand the potential for amplified ground shaking and to evaluate lateral variability in shear-wave velocity at these sites. We deployed up to 88 geophones at 2-m or 4-m...

Fire history metrics enable rapidly increasing amounts of burned area data to be collapsed into a handful of data layers that can be used efficiently by diverse stakeholders. In this effort, the U.S. Geological Survey's Landsat Burned Area product was used to identify burned area across CONUS over a 40-year period (1984-2023). The Landsat BA product was consolidated into a suite of annual BA products, which in-turn were used to calculate a series of contemporary fire history metrics (30 m resolution). Fire history metrics included: (1) fire frequency (FRQ), (2) time since last burn (TSLB) and (3) year of last burn (YLB), (4) longest fire-free interval (LFFI), and (5) average fire interval length (FIL). All metrics...

Very large wrinkles (forming stairway in photograph) in schist in the northern part of the area. The main schistosity and the bedding strike north 60 degrees west and dip 50 degrees southwest (parallel to the crests of the wrinkles). A second schistosity is developed locally that strikes north 67 degrees east and dips 40 degrees northwest (parallel to the axial planes of the Wrinkles). The geologic pick rests on a sinuous quartz vein about 1 inch thick that follows the crenulations of wrinkles. The knobby character of the schist is caused by quartz-sillimanite knots. Custer County South Dakota. Published in U. S. Geological Survey Bulletin 1142-E. 1963.

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...

This data release (version 2.0, July 2021) consists of a Microsoft® Access database that contains groundwater withdrawal estimates from 1913 to 2016 for the Death Valley regional groundwater flow system (DVRFS). The four tables in the database also are provided as individual comma-separated values (CSV) files. This version (2.0) of the data release contains the most current version of the database and supersedes all previous versions. A total of about 41,000 acre-ft of groundwater were withdrawn from DVRFS in 2016 of which 51 percent was used for irrigation, 20 percent for domestic, and 27 percent for public supply, commercial, and mining activities. The total groundwater withdrawals for Pahrump Valley (hydrographic...
