This data release contains estimates of mean daily gross primary production (GPP) and ecosystem respiration (ER) in Bronson and Fanno Creeks, Oregon during August of 2016. These estimates were part of a larger study of the water-quality effects of beaver dams and beaver activity in selected urban streams of the Tualatin River Basin in northwestern Oregon. The mean daily GPP and ER values were estimated using two approaches (both of which are publicly available and documented): 1) a USGS model developed using the R programming language and 2) a Washington Department of Ecology model that runs in Excel. Inputs for the models included hourly measurements of dissolved-oxygen concentration, water temperature, photosynthetically...

This metadata record describes a series of tabular datasets containing metrics used to characterize drought for select United States Geological Survey (USGS) streamgages for the climate years (April 1 – March 31) 1921 to 2020. These streamgages are a subset of those used in Geospatial Attributes of Gages for Evaluating Streamflow, version 2 (GAGES-II, Falcone, 2011) in the conterminous United States (CONUS). These metrics include streamflow percentiles, identified drought events, annual low streamflow, and drought statistics for each event.
This dataset contains two-dimensional hydraulic models throughout the Willamette River, extending from the McKenzie River confluence, near Eugene, to the city of Newberg. The study reach is separated into five individual models to simplify tributary inflow boundary conditions and for run-time efficiency. These models were developed to assess juvenile salmonid habitat at streamflows ranging from typical low summer flows to roughly the median annual high flow along each reach. Steady-state streamflow conditions were simulated in an unsteady flow simulation by holding streamflow constant for longer periods of time. Underlying these models is a digital elevation model, which combines bathymetric lidar, collected in...

Interactions between geomorphic processes at multiple scales shape the distributions of habitats, species, and life stages that a river can support. Understanding these hierarchical processes may be helpful for proactive monitoring and restoration of native Western Brook Lamprey (Lampetra richardsoni) and Pacific Lamprey (Entosphenus tridentatus) in Pacific Northwest rivers. The processes creating thick, fine-grained sediment deposits that lamprey larvae rely on as rearing habitat were assessed in part through field sampling in the Umpqua River basin, southwestern Oregon, USA. Local factors, such as substrate, boulders, wood, and water, that control sediment erosion and deposition, affecting larval lamprey habitat,...

Water-surface elevations were recorded by 17 submerged water level loggers between March and October, 2016 along a 3 kilometer reach of the upper Deschutes River, Oregon. 15 water level loggers were installed along the channel margins and 2 loggers were placed in off-channel wetland ponds. Submerged depths recorded at each logger were converted to water surface elevations using real-time kinematic global positioning system (RTK-GPS) measurements of water surface elevation near each water level logger location. Water surface elevation recorded at the loggers captured discharges ranging from approximately 600 to over 2,000 cubic feet/second recorded at the Bureau of Reclamation gage at Benham Falls.

This data release contains the results from a study of the transport and transformation of nitrate in groundwater and streams across diverse glacial terranes within the Western Lake Michigan (WMIC) Drainages and Eastern Iowa (EIWA) Basins of the United States. The primary focus of the study was on how varying redox conditions influence the timing and delivery of nitrate to streams in agricultural watersheds. The data represents dissolved gas modeling results that were obtained from the Dissolved Gas Modeling and Environmental Tracer Analysis (DGMETA) software program. DGMETA was used to produce calibrated dissolved gas models that provide optimal recharge temperature, excess air, and excess nitrogen gas concentrations...
This dataset contains manually developed 5-, 10-, and 500-ft contours for the Harney Basin, Oregon aquifer system shallow and deep potentiometric-surface maps. The potentiometric-surfaces show altitude at the water-table surface (shallow) and at which the water level would have risen in tightly-cased wells deeper than 100 ft (deep) and generally represents synoptic conditions during February–March of 2018. The water-table map was developed using groundwater-level measurements from shallow wells (generally less than 100 ft deep in the lowlands) and the altitudes of springs and gaining stream reaches and constrained by the altitude of the land surface. The deeper potentiometric-surface map was developed using measurements...
