Data

In June and September, 2022, NV5 Geospatial collected aerial imagery and near-infrared (NIR) lidar from crewed aircraft over 62 square kilometers over headwater streams in the Donner und Blitzen River watershed in southeastern Oregon. Repeat data were collected along Mud Creek and Bridge Creek on the western slope of Steens Mountain. This data release includes orthoimagery and lidar data

In June and September 2022, NV5 Geospatial collected aerial imagery and near-infrared (NIR) lidar from crewed aircraft over 34 square kilometers of headwater streams in the Breitenbush River Basin in northwestern Oregon. Repeat aerial imagery and NIR lidar data were collected over an area spanning from the northern slope of Triangulation Peak to the mainstem Breitenbush River near the...

This data release presents truth data and benchmark results describing simulation of hydrologic drought events in the conterminous United States. This data release supports a publication (Simeone and others, 2024) which documents drought benchmarking methods and their application to the results of the National Water Model (NWM) version 2.1. Truth data used were observations at U.S...

This data release presents truth data and benchmark results describing simulation of hydrologic drought events in the conterminous United States. This data release supports a publication (Simeone and others, 2024) which documents drought benchmarking methods and their application to the results of the National Hydrologic Model Precipitation-Runoff Modeling System v1.0 (NHM-PRMS). Truth...

A spreadsheet-based model (using Microsoft Excel) was developed to assess the amounts and types of habitats within the Malheur National Wildlife Refuge in southeastern Oregon, USA. The Refuge provides critical bird habitat, and the model was designed to quantify the areas of open water, partial water, and water depths during the irrigation season (April–July) from 2021–2024. This data...

This model archive summary (MAS) and associated model calibration data describes a surrogate model used to compute point location suspended sediment concentrations at USGS streamgage 11510700 for water years 2019-2023. The methods used follow USGS guidance as referenced in Office of Surface Water (OSW)/Office of Water Quality (OWQ) technical memoranda 2016.07 and USGS techniques and...

This data release contains estimated monthly point-source nutrient loads for 97 municipal wastewater treatment plants, 20 industrial facilities, and 46 fish hatcheries and other aquaculture facilities that discharge within the watersheds draining to Puget Sound and the Strait of Juan de Fuca in Washington, or discharge directly to those water bodies. The data, which cover the years 2005...

This data release consists of a two-dimensional (laterally averaged) hydrodynamic water-quality model (CE-QUAL-W2; Wells, 2019) of Green Peter and Foster Lakes for the 2023 calendar year, and three theoretical deep drawdown operational scenarios that apply the 2023 model to calendar year 2024. The model and scenarios were used to gain insights into the thermal processes in Green Peter...

This metadata record describes a series of tabular datasets containing metrics used to characterize periods of anomalously low storage for select large reservoirs across the Conterminous United States for the climate years (April 1 – March 31) from 1981 to 2020. These data support the associated Simeone and others (2024) publication. The reservoirs in this dataset are those included in...

The 2022 Department of the Interior, Environment, and Related Agencies Appropriations Bill - the appropriations bill that funds the USGS - established a regional Integrated Water Availability Assessment study program in the Great Basin of the American West. Twenty saline lakes across California, Nevada, Oregon, and Utah were identified by USGS partners as priority ecosystems. They...

This data release contains plankton sampling results collected in the Willamette River in Portland, Oregon. The data release will be updated with new results as they are collected. The samples in this data release were collected at USGS stations 453027122400000 (Willamette River below the Holgate Channel), 452913122394300 (Ross Island Lagoon – Willamette River), and 453833122462700...

This USGS data release presents data used to estimate and summarize where and when recharge occurs to the Columbia River Basalt Group (CRBG) in the Umatilla River basin, Oregon, 2014–2022. The supplemental data consist of two child items. The child items are: (1) Discrete geochemical data for groundwater and surface water samples in the Umatilla River basin, 2014–2022, and (2) Dissolved...
