Water chemistry data for samples collected at groundwater sites in the Montebello Oil Field study area, September 2014–October 2018, Los Angeles County, California Water chemistry data for samples collected at groundwater sites in the Montebello Oil Field study area, September 2014–October 2018, Los Angeles County, California
The California State Water Resources Control Board (State Water Board) initiated the Regional Groundwater Monitoring Program (RMP) to assess effects of oil and gas development on groundwater designated for any beneficial use. The U.S. Geological Survey (USGS) is the technical lead in conducting the RMP through the California Oil, Gas, and Groundwater (COGG) Program, working in...
Potential Explanatory Factors for Groundwater Quality in the Sacramento Metropolitan Domestic-Supply Aquifer Study Unit, 2017: California GAMA Priority Basin Project Potential Explanatory Factors for Groundwater Quality in the Sacramento Metropolitan Domestic-Supply Aquifer Study Unit, 2017: California GAMA Priority Basin Project
This data release codifies and attributes explanatory factors that could potentially impact groundwater quality at 49 groundwater sites used for domestic water supply in the Sacramento Metropolitan Domestic-Supply Aquifer Study Unit (SacMetro-DSA). Water quality from domestic groundwater sites in the SacMetro-DSA was assessed as part of the California State Water Resources Control Board...
Biophysical drivers for predicting the distribution and abundance of invasive yellow sweet clover in the Northern Great Plains Biophysical drivers for predicting the distribution and abundance of invasive yellow sweet clover in the Northern Great Plains
Yellow sweetclover (Melilotus officinalis; YSC), an invasive biennial legume, bloomed throughout the Northern Great Plains (NGP) following greater-than-average precipitation during 2018-2019. YSC can increase nitrogen (N) levels and potentially cause broad changes in the composition of native plant species communities. There is little knowledge of the drivers behind its spatiotemporal...
Central Valley Hydrologic Model version 2 (CVHM2): Well Log Lithology Database and Texture Model Central Valley Hydrologic Model version 2 (CVHM2): Well Log Lithology Database and Texture Model
These data encompass the geologic framework model for the Central Valley Hydrologic Model Version 2 (CVHM2) study. This includes (1) the Well Log Database which contains borehole information and lithology used in creating the geologic framework, (2) Well Logs with Classification Information which explains how percent coarse values were determined for each borehole, and (3) the Three...
Chemical characterization of water, sediments, and fish from Water Conservation Areas and Canals of the Florida Everglades (USA), 2012 to 2019 Chemical characterization of water, sediments, and fish from Water Conservation Areas and Canals of the Florida Everglades (USA), 2012 to 2019
This dataset includes field and laboratory measurements of surface waters, pore waters, sediment, and fish from Water Conservation Areas and adjacent canals of the Florida Everglades (USA). Water, sediment, and fish samples were collected from Water Conservation Areas 1 (Arthur R. Marshall Loxahatchee National Wildlife Refuge), 2, and 3 and neighboring canals between 2012 and 2019. The...
Updated CONUS river network attributes based on the E2NHDPlusV2 and NWMv2.1 networks (ver. 2.0, February 2023) Updated CONUS river network attributes based on the E2NHDPlusV2 and NWMv2.1 networks (ver. 2.0, February 2023)
The comid field of these data can be used to join to the NHDPlus version 2 flowline comid or catchment featureid attributes. The included attributes follow the same data model as the NHDPlusV2 but include numerous updates and improvements to network connectivity. All attributes that depend on network connectivity have been recalculated. These attributes are based on the National...
