Introduction Potential offsite impacts to public and ecosystem health from exposure to current-use pesticides and other organic contaminants are a growing concern in Hawaiʻi. In response to these concerns, the U.S. Geological Survey (USGS), in cooperation with the State of Hawaiʻi Department of Agriculture (HDOA), initiated a comprehensive pesticide-monitoring program of surface water in Hawaiʻi in 2016. The State of Hawaiʻi Department of Health (HDOH) is collaborating by providing technical and scientific assistance. The objectives of the Hawaiʻi pesticide-monitoring program include (1) documenting the occurrence and distribution of current-use pesticides in surface water of geographically distinct agricultural...

The supplemental data presented here contains raster data in .tif format of the empirically estimated mean annual (1987-2015) net evapotranspiration (ETnet) for the Harney Basin Groundwater Evapotranspiration Area. The final mean annual ETnet estimate for the Harney Basin was determined using both empirical and physics-based methods. The final ETnet estimate was combined with additional data to estimate groundwater discharge through evapotranspiration (ET) in the Harney Basin. See Garcia and others (2022) for a detailed description of how these data were estimated and evaluated.

The supplemental data presented here contain tabular data (in .csv format) including measured and estimated daily and water-year (1982–2016) streamflow for selected watersheds and estimated springflow at Page Springs in Harney Basin. Daily streamflow data are a composite of measured streamflow and extended streamflow records from short-term streamgages in gaged watersheds. Short-term or discontinuous records in gaged watersheds were extended to the period 1982–2016 using the Kendal-Thiel Robust Line (KTRL) method (Helsel and Hirsch, 2020) and ordinary-least squares (OLS) linear regression. Springflow estimates were provided by the U.S. Fish and Wildlife Service.
The supplemental data presented here contain shapefiles of the hydrographic area, regions, groundwater evapotranspiration areas, and select watersheds in Harney Basin used in the hydrologic budget of the Harney Basin groundwater system, 1982-2016 report.

The supplemental data presented here contains three raster datasets representing the evapotranspiration (ET) units for northern, southern, and western regions of Harney Basin (raster datasets in .tif format) and one vector dataset of ET-unit observations used to delineate ET units (vector dataset in .shp format). Eleven ET units were identified from ET-unit observations of land cover and include bare soil or playa (1), marsh (2), dry meadow (3), wet meadow (4), open water (5), riparian (6), mixed shrubland (7), phreatophyte shrubland (8), xerophyte shrubland (9), sagebrush shrubland (10), and xerophyte grassland (11). Irrigated areas are excluded from ET units. Unpublished land-cover datasets collected by the U.S....

This data release presents tabular data used and analytical water-level modeling files generated as part of a U.S. Geological Survey study, done in cooperation with the Confederated Tribes of the Umatilla Indian Reservation, to evaluate water-level change from a multiple-well aquifer test in well 422 on the Umatilla Indian Reservation near Mission, Oregon. Water-level, pumping, and barometric-pressure data collected during February 1, 2016–April 18, 2016 were used within the accompanying water-level modeling files to estimate drawdown in observation and background wells from the aquifer test. Water-level models were created within Excel spreadsheets using an Excel Add-in called SeriesSEE (Halford and others, 2012)....

The supplemental data presented here contain a macro-driven Microsoft Excel workbook (Office 365 format) that was developed to simultaneously balance streamflow with precipitation distributions in the Harney Basin for streamgaged and ungaged upland watersheds and other upland areas. The workbook allows for as many as five precipitation ranges to be manually specified. Precipitation for the area within each range is summed by watershed or ungaged area and multiplied by a fitted coefficient to estimate precipitation-derived streamflow.
The U.S. Geological Survey Pacific Islands Water Science Center and the University of Hawaii at Manoa Department of Geography, in cooperation with the U.S. Department of Interior Pacific Islands Climate Adaptation Science Center initiated a field data-collection program as part of a study to quantify the impacts of drought on water resources and the importance of cloud-water interception in mitigating the impacts of drought (see Related External Resources link below). The goal of the data-collection program is to provide information for evaluating the role that cloud-water interception in Hawaii’s rain forests has in providing moisture for plants, reducing wildfire risk within the fog zone, and contributing to groundwater...
