Substrate Size Data for Kalamazoo River Reference Reach upstream of Plainwell, Michigan, 2022

In August, 2022, pebble counts were conducted in a reference reach of the Kalamazoo River upstream of Plainwell, Michigan (MI) to characterize the substrate size within the reach. These data were collected to accompany elevation data collected for the reference reach in October, 2021. A reach composite pebble count was conducted, consisting of 101 samples collected along 34 transects spanning the entire 500 m reach. Sample locations spanned multiple geomorphic unit types, including riffles, pools, and run/glides. Additionally, a separate 100-sample pebble count was conducted in a riffle near the head of the reference reach. The riffle data were collected in the same location as a 2010 survey and pebble count, allowing comparison over time. 
Substrate size was measured with a gravelometer for sediment &gt;2 mm and with a sand card for sediment in the 0.063 mm - 2.0 mm range. For both the reach composite and riffle cross-section counts, sediment size ranged from silt/clay (&lt; 0.063 mm) to &gt;90 mm. In addition to the quantitative measurements, samples were also characterized categorically following methods used in previous post-oil spill substrate mapping in the Kalamazoo River, which was used in sediment remediation assessments (TetraTech, 2012). Finally, measurements of soft sediment depth were recorded, where it was present overlying the bed surface.

Microhabitat characteristics influencing sage-grouse nest site selection and survival, Nevada and California (2012-2017)

We examined nest survival of Greater Sage-grouse (Centrocercus urophasianus; hereafter, sage-grouse) in relation to fine-scale habitat patterns that influenced nest site selection, using data from nests of telemetered females at 17 sites across 6 years in Nevada and northeastern California, USA. Importantly, sites spanned mesic and xeric average precipitation conditions and concomitant vegetation community structure across cold desert ecosystems of the North American Great Basin. Vegetative cover immediately surrounding sage-grouse nests was important for both nest site selection and nest survival, but responses varied between mesic and xeric sites. For example, while taller perennial grass was selected at xeric sites, we found no evidence of selection for perennial grass at mesic sites indicating a functional response to availability of habitat features between hydrographic regions. Furthermore, perennial grass height and forb height both had positive effects on nest survival at xeric sites, but we found varying effects at mesic sites. We emphasize that precipitation conditions driving ecosystem productivity vary regionally among sagebrush communities and shape vegetation characteristics facilitating suitable habitat conditions for nesting sage-grouse.

Groundwater elevation data and models in and around select California oil fields (ver. 3.0, September 2025)

This data release contains groundwater elevation data and the associated model/code used to create groundwater elevation surfaces in and around select oil fields in California. The data and model provided here are intended to supplement interpretative manuscripts. Specific study areas will be added as Child Items found in this data release.
Groundwater elevations are usually collected from individual wells at discrete times. However, we are often interested in looking at a continuous surface of groundwater levels for a variety of reasons including to examine potential gradients, or directions of groundwater flow. Therefore, we created continuous space-time models of groundwater elevations using a Gaussian process. These datasets have two distinct data types, 1) groundwater elevations measured in water wells obtained from the California Department of Water Resources and the California State Water Resources Control Board's GeoTracker, and 2) elevations of the water table interpreted from oil and gas geophysical well logs. Using both data types provide unique spatial and temporal data coverage in and around oil fields in California. Modeling both data types together allow us to examine lateral gradients between oil fields and adjacent groundwater basins. We can also estimate potential vertical gradients by comparing the modeled water table to fluid levels derived from idle oil and gas wells perforated in deeper hydrocarbon reservoirs. 
The data compiled and analyzed here are part of the California State Water Resources Control Board Oil and Gas Regional Monitoring Program and the U.S. Geological Survey California Oil, Gas, and Groundwater (COGG) Program.

Woody Debris in Kalamazoo River Reference Reach upstream of Plainwell, Michigan, 2021

This dataset is a polygon shapefile of woody debris in an approximately 500 meter (m) reach of the Kalamazoo River upstream of Plainwell, Michigan (MI). The woody debris was identified using terrestrial lidar data collected in October 2021. The lidar point cloud was classified as ground, water, and vegetation returns by a combination of automated and manual methods. Woody debris points in the channel were manually classified with the aid of imagery that was collected concurrently with the lidar data. These points were used to generate polygons defining the outline of woody debris in the channel. Because lidar does not penetrate the water surface, only vegetation extending above the water surface was mapped. Fully submerged debris could not be detected.

Irrigation water use reanalysis for the 2000-20 period by HUC12, month, and year for the conterminous United States (ver. 2.0, September 2024)

This data release provides a monthly irrigation water use reanalysis for the period 2000-20 for all USGS Watershed Boundary Dataset of Subwatersheds (Hydrologic Unit Code 12 [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 Model (NHM; Regan and others, 2019) to estimate consumptive use and effective precipitation on irrigated lands. Irrigated lands for the CONUS were provided by the Landsat-based Irrigation Dataset (LANID; Xie and others, 2019) for each year of the reanalysis period. Consumptive use estimates provided by the NHM were disaggregated to HUC12s using area weighted intersections with HRUs and the relative proportion of irrigated lands in each intersected area.
This data release includes data and source code required to develop the irrigation reanalysis workflow along with the scripts and data required to replicate the output results. The workflow has three main steps that were automated using python scripts: 1) convert daily OpenET/SSEBop results into input for the NHM, 2) run a modified version of the NHM that is an application of the GSFLOW software package (GSFLOW version 2.3) to estimate daily results, and 3) post-process NHM results to monthly, then summarize and disaggregate ETo, ETa, irrigated areas, consumptive use, and effective precipitation to all HUC12s in the CONUS for the period 2000-20.

Stable hydrogen and oxygen isotopic compositions of precipitation samples from selected Colorado and Utah National Atmospheric Deposition Program (NADP) sites

The stable hydrogen (delta 2H) and oxygen (delta 18O) isotopic compositions of more than 4,300 weekly composite samples of precipitation from thirteen National Atmospheric Deposition Program (NADP) sites (CO02, CO08, CO09, CO10, CO21, CO89, CO91, CO92, CO93, CO96, CO97, CO98, and UT09) in Colorado and Utah were analyzed on archived samples obtained from NADP over various time periods between January 2001 and October 2022. Measured values range between –271.6 and +18.3 per mil for delta 2H and between –35.19 and +6.64 per mil for delta 18O. This data set includes values from all the samples that were analyzed so that measurement uncertainty related to sample volume can be evaluated. Data on collection begin and end dates, sample volume and precipitation amounts were furnished from NADP and were not evaluated for accuracy.  Due to sample volume and storage times, some isotope-delta values have been flagged as being out of range for natural waters; however, the end user is responsible for evaluating all data for suitability to the intended purpose.
Data files provided here include the metadata as an .xml file, a Microsoft Office Excel .xlsx file with four spreadsheets containing the Introduction, Table 1, Table 2, and Table 3, and the individual data tables as comma-separated value .csv files. A plot of hydrogen versus oxygen isotopic compositions is also provided as a .jpg image. Data analysis was funded by the U.S Geological Survey (USGS) National Research Program, the USGS Climate Research and Development Program, and the USGS Next Generation Water Observing System (NGWOS) Program.

Results of the Water Balance evaluation and supplemental data for publication

We developed an improved approach to the parameterization of the Operational Simplified Surface Energy Balance (SSEBop) model using the Forcing and Normalizing Operation (FANO). The FANO parameterization was implemented on two computing platforms using Landsat and gridded meteorological datasets: 1) Google Earth Engine (GEE) and 2) Earth Resources Observation and Science (EROS) Center Science Processing Architecture (ESPA). FANO brought substantial improvements in model accuracy and operational implementation.

Attributes for NHDPlus Version 2.1 Reach Catchments and Modified Routed Upstream Watersheds: 30 year (1981 - 2010) average of annual maximum duration of consecutive dry and wet days per event for the Conterminous United States and District of Columbia

This tabular data describes the average of annual maximum duration of consecutive dry and wet days per event, where precipitation totals are 0 or equal and exceeds 1 millimeters respectively, during the 30-year period 1981 – 2010 for two spatial components of the NHDPlus version 2 data suite (NHDPlusv2) for the conterminous United States; 1) individual reach catchments and 2) reach catchments accumulated upstream through the river network.  A wet event is defined as a period when the number of consecutive days with precipitation equals or exceeds 1 millimeter.  A dry event is defined as a period when the number of consecutive days with precipitation equals 0 millimeters. This dataset can be linked to the NHDPlus version 2 data suite by the unique identifier COMID. The source data for 30 year (1981-2010) average of annual maximum duration of consecutive dry and wet days per event was a 1-kilometer resolution GeoTIFF file that was produced and acquired from DAYMET (2018). Reach catchment information characterizes data at the local scale. Reach catchments accumulated upstream through the river network characterizes cumulative upstream conditions.  Network-accumulated values are computed using two methods, 1) divergence-routed and 2) total cumulative drainage area. Both approaches use a modified routing database to navigate the NHDPlus reach network to aggregate (accumulate) the metrics derived from the reach catchment scale. (Schwarz and Wieczorek, 2018).
