Controlled source audio-frequency magnetotellurics (CSAMT) data from the Big Chino Wash and Paulden areas, Yavapai County, Arizona
Controlled source audio-frequency magnetotellurics (CSAMT) data were collected in the Big Chino Valley and Paulden areas, Yavapai County, Arizona, to better understand the hydrogeology of the area. CSAMT data provide vertical cross-section (profile) data about the resistivity of the subsurface, which may be related to lithologic boundaries and (or) grain-size distribution in the subsurface....

Access to current conditions, historical observations, daily data, statistics, peak-flow data, and field measurements for streamflow gaging stations in Arizona.
High-Water Mark Survey of July 10, 2018, Flood at I-10 Frontage Rd at Twin Peaks Rd, Marana, AZ
A train derailment occurred in Marana, Arizona, on July 10, 2018. Runoff from a severe thunderstorm was flowing over the tracks at the time and may have contributed to the derailment. At the request of the Pima County Regional Flood Control District, USGS collected high-water marks for the flood event upstream from the derailment area.
Code for use within Matlab for computing the damping and lag time of responses to cyclical infiltration in a layered vadose zone in Central Valley, California
This data release contains code for computing the filtering properties of cyclical infiltration in a layered vadose zone in Central Valley, California. The code for computing the filtering is described in a manuscript that is under review at Vadose Zone Journal. The updated data contained in this data release are the code to compute the filtering properties of the vadose zone....
Overview Metadata for the Data used in te Conceptual and Numerical Model of the Colorado River (1990-2016)
This data release contains six different datasets that were used in the report SIR 2018-5108. These datasets contain discharge data, discrete dissolved-solids data, quality-control discrete dissolved data, and computed mean dissolved solids data that were collected at various locations between the Hoover Dam and the Imperial Dam.

Overview Metadata for the Regression Model Data, Estimated Discharge Data, and Calculated Flux and Yields Data at Tumacácori National Historical Park and the Upper Santa Cruz River, Arizona (1994-2017)
This data release contains three different datasets that were used in the Scientific Investigations Report: Spatial and Temporal Distribution of Bacterial Indicators and Microbial Source Tracking within Tumacácori National Historical Park and the Upper Santa Cruz River, Arizona, 2015-16. These datasets contain regression model data, estimated discharge data, and calculated flux and...
Supplemental discrete dissolved-solids and specific conductance data and monthly mean dissolved-solids load data in the lower Colorado River, 1928-2016
Monthly Mean Dissolved-Solids Concentration and Monthly Mean Dissolved-Solids Load Data Flow weighted monthly mean dissolved-solids concentrations (mg/L) data and monthly mean dissolved-solids load data from 1928-2016 were computed by USGS using raw data from the Bureau of Reclamation. These data were computed by USGS for all of the seven sites (listed below). Colorado River above...
