Soil-Water Balance Groundwater Infiltration Model Results for the Grand Canyon region within the Lower Colorado River Basin, monthly results, 1950-2099, mean temperature

The Colorado River and its tributaries supply water to more than 35 million people in the United States and 3 million people in Mexico, irrigating more than 4.5 million acres of farmland, and generating about 12 billion kilowatt hours of hydroelectric power annually. Planning for the sustainable management of the Colorado River in future climates requires an understanding of the Lower Colorad...

Soil-Water Balance Groundwater Recharge Model Results for the Lower Colorado River Basin

This USGS Data Release represents Soil-Water Balance (SWB) groundwater infiltration modeling results for the Lower Colorado River Basin (LCRB). The data release was produced in compliance with 'open data' requirements as a way to make the scientific data associated with USGS research efforts and publications available to the public. There are 3 separate groups of datasets associated

Soil-Water Balance Groundwater Infiltration Model Results for the alluvial basins in Arizona within the Lower Colorado River Basin, monthly results, 1950-2099, mean temperature

The Colorado River and its tributaries supply water to more than 35 million people in the United States and 3 million people in Mexico (Bureau of Reclamation, 2011), irrigating more than 4.5 million acres of farmland, and generating about 12 billion kilowatt hours of hydroelectric power annually (Colorado River Basin Salinity Control Forum, 2011). Planning for the sustainable mana

Water Quality Parameters in the Verde River below Granite Creek, Arizona, June 2018

Water quality parameters (water temperature, specific conductance, pH, dissolved oxygen, air temperature, and barometric pressure) were measured in the Verde River over a half mile reach below the confluence with Granite Creek. Measurements were made using a calibrated In-Situ SmarTROLL multiparameter meter on June 13, 2018.

Carbon and Strontium Isotopic Data for Rock, Soil, and Soil Gas from the Big Chino Sub-Basin, Arizona 2017 and 2018

Dataset includes rock and soil gas carbon and strontium values. Soil gas samples were collected from different depths in augered soil core holes. Material at the bottom of the soil core hole was analyzed in addition to soil gas for some samples. Rock samples were collected from outcrop locations as well as from drill cuttings.

09487000 - Brawley Wash near Three Points, AZ - 2018/09/19 GPS Survey

The dataset contains GPS survey data from two surveys conducted after a flow event on September 19, 2018, at the USGS streamgage 09487000 - Brawley Wash near Three Points, AZ. The first survey, on October 1, 2018, documents cross section geometry and high-water marks from the flow event in the reach downstream from the gage. The second survey, on January 31, 2019, documents addi

Absolute gravity data from Pinal County, Arizona, 2019

This dataset contains absolute-gravity measurements made using an A-10 absolute gravity meter (Micro-g Lacoste, Inc.) in 2019 in Pinal County, Arizona. Measurements were made at a total of 19 different stations used by the Arizona Department of Water Resources (ADWR) to monitor aquifer-storage changes. Data are presented in tabular and spatial vector (point) form, including rele

Controlled source audio-frequency magnetotellurics (CSAMT) data from the Grand Canyon West and Plain Tank Flat areas of the western Hualapai Reservation, Arizona

Controlled source audio-frequency magnetotellurics (CSAMT) data were collected in the Grand Canyon West and Plain Tank Flat areas of the western Hualapai Reservation, 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) g

Repeat microgravity data from the Big Chino Subbasin, 2001-2017, Yavapai County, Arizona

This dataset contains absolute-gravity measurements made using an A-10 absolute gravity meter (Micro-g Lacoste, Inc.) between 2009 and 2017 in the Big Chino Subbasin, Yavapai County, Arizona. Measurements were made about 3 times per year at a total of 33 different stations. Data are presented in tabular form, including relevant parameters used for processing. Data were output by g sof

Repeat microgravity data from Tucson Basin and Avra Valley, Arizona, 2016-2019 (ver. 2.0, August 2019)

This dataset supercedes an earlier data release and includes all previous data in addition to data from 2019. These data represent the network-adjusted results of relative- and absolute-gravity surveys. Relative-gravity surveys were carried out using a Micro-g LaCoste D-series relative-gravity meter. The effect of solid Earth tides and ocean loading were removed from the data. Instrument drift...

Spatial and temporal variability of peaks and seasonal maximum flows in the Conterminous U.S. from cluster analysis of standardized streamflow obtained from the USGS National Water Information System

This dataset contains annual peak and seasonal maximum streamflow data from the USGS National Water Information System (NWIS) and the results of an analysis of spatial and temporal patterns for those data for the conterminous U.S. An interpretation of the analysis of these data will be published in a journal article. The streamflow data were compiled for the years 1966 to 2015 for 415 streamg...

09471143 - Walnut Gulch below ARS Flume 6, near Tombstone, AZ - 07/28/2017 Continuous Slope-Area

Continuous slope-area (CSA) sensors are installed at four cross sections downstream from Flume 6 operated by the Agricultural Research Service (ARS) at the Walnut Gulch Experimental Watershed. A flow event occurred on July 28, 2017. Stage data were recorded by submersible pressure transducers at each of the four cross sections. The stage data, along with cross section geometry and fie
