This USGS Data Release represents water and sediment quality data collected in the Grand Canyon region of northern Arizona. This dataset comprises water quality results from spring and stream sites in Grand Canyon that were sampled through a cooperative effort by U.S. National Park Service (NPS) personnel during 2016 and 2017. NPS personnel collected water samples from spring and stream sites in Grand Canyon. Water samples were filtered using a syringe and 0.45 µm filter and preserved with nitric acid. Filtered and preserved samples were analyzed by the USGS Geology, Geophysics, and Geochemistry Science Center Laboratory for a suite of elements using inductively coupled plasma - mass spectrometry (ICP-MS) methods...

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. CSAMT involves transmitting a current at various frequencies in one location, and measuring resistivity differences between electrodes spaced along a receiver line several kilometers from the transmitter. Data were collected using a GGT-30 transmitter and GDP32-II receiver (Zonge international. Inc.). Data processing and inversions...
This dataset comprises water quality results from monitoring sites on major tributaries of the Colorado River in the Grand Canyon region beginning in 2015. These tributary sites include Little Colorado River above the mouth near Desert View, Arizona (USGS site ID 09402300); Kanab Creek above the mouth near Supai, Arizona (USGS site ID 09403850); Havasu Creek above the mouth near Supai, Arizona (USGS site ID 09404115); House Rock Wash below Emmett Wash in Rider Canyon, Arizona (USGS site ID 363851111482000); and Paria River at Lees Ferry, Arizona (USGS site ID 09382000). Monitoring of the Little Colorado River, Kanab Creek, and Havasu Creek sites began in 2015, with other sites added later.

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) grain-size distribution in the subsurface. CSAMT involves transmitting a current of electricity at various frequencies in one location, and measuring the magnetic response and electrical current between electrodes spaced along a receiver line several kilometers from the transmitter. Data were collected using a GGT-30 transmitter and GDP32-II...

There are 3 separate datasets associated with this Data Release: SWB model results from simulations run using projected climate data, summarized by month from 1950 through 2099, for the LCRB within the United States SWB model results from simulations run using projected climate data, summarized by month from 1950 through 2099, for the Grand Canyon region SWB model results from simulations...
This is a release of data presented in the report "Binational Study of the Transboundary San Pedro Aquifer", Callegary and others, 2016: Callegary, J.B., Minjárez Sosa, I., Tapia Villaseñor, E.M., dos Santos, P., Monreal Saavedra, R., Grijalva Noriega, F.J., Huth, A.K., Gray, F., Scott, C.A., Megdal, S.B., Oroz Ramos, L.A., Rangel Medina, M., Leenhouts, J.M., 2016, Binational Study of the Transboundary San Pedro Aquifer: International Boundary and Water Commission. The United States and Mexico share waters in a number of hydrological basins and aquifers that cross the International Boundary. Both the United States and Mexico recognize that, in a region of scarce water and expanding populations, better...

This USGS Data Release represents time series water quality data collected at select spring sites in the Grand Canyon region of northern Arizona. This dataset comprises time series water quality results from select spring sites in the Grand Canyon region that were sampled using a MiniSipper auto sampler. These spring sites include Salt Spring (USGS Site ID: 360439112094101) and Willow 1 Spring (Site ID: 363357112440801). The MiniSipper auto sampler collects up to 250 five-mL, 0.45 um filtered and acidified water samples. Samples are stored in a 500' teflon tubing sample coil and adjacent water samples are separated by air bubbles (Chapin and Todd, 2012). Water samples are analyzed for a suite of elements using...
