Water Budget of the Sierra Vista Subwatershed of the Upper San Pedro Basin, 2002 - 2012 and 2020 Water Budget of the Sierra Vista Subwatershed of the Upper San Pedro Basin, 2002 - 2012 and 2020
Groundwater budgets were compiled from 2002 to 2012 and 2020 for the Sierra Vista Subwatershed for the Upper San Pedro Partnership. In 2012, the annual groundwater budget was estimated to be about -5,000 acre-ft per year (negative values indicate a deficit, where more water is removed from the system than is being returned; positive values indicate a surplus, where more water is entering...

Hydrologic framework and characterization of the Little Colorado River alluvial aquifer near Leupp, Arizona Hydrologic framework and characterization of the Little Colorado River alluvial aquifer near Leupp, Arizona
The Little Colorado River alluvial aquifer near Leupp, Arizona, was investigated as a possible source of irrigation water for the Leupp and Birdsprings Chapters of the Navajo Nation. The physical, chemical, and hydraulic characteristics of the alluvial aquifer were studied using geophysical surveys, installation of observation wells, water-level measurements, chemical analyses...

Occurrence and transport of aerially applied herbicides to control invasive buffelgrass in Rincon Mountain District, Saguaro National Park, Arizona Occurrence and transport of aerially applied herbicides to control invasive buffelgrass in Rincon Mountain District, Saguaro National Park, Arizona
Resource managers of the Saguaro National Park are concerned about the spread of the invasive species Cenchrus ciliaris L. (buffelgrass) and the threat it poses to desert ecosystems. Glyphosate-based herbicide treatments seem to be one of a few viable options to control the spread of buffelgrass in the mountainous terrain of the National Park. The U.S. Geological Survey completed a 4...

Assessing potential groundwater-level declines from future withdrawals in the Hualapai Valley, northwestern Arizona Assessing potential groundwater-level declines from future withdrawals in the Hualapai Valley, northwestern Arizona
A numerical groundwater flow model of the Hualapai Valley Basin in northwestern Arizona was developed to assist water-resource managers in understanding the potential effects of projected groundwater withdrawals on groundwater levels in the basin. The Hualapai Valley Hydrologic Model (HVHM) simulates the hydrologic system for the years 1935 through 2219, including future withdrawal...

Occurrence, fate, and transport of aerially applied herbicides to control invasive buffelgrass within Saguaro National Park Rincon Mountain District, Arizona, 2015–18 Occurrence, fate, and transport of aerially applied herbicides to control invasive buffelgrass within Saguaro National Park Rincon Mountain District, Arizona, 2015–18
The spread of the invasive and fire-adapted buffelgrass (Cenchrus ciliaris L.) threatens desert ecosystems by competing for resources, increasing fuel loads, and creating wildfire connectivity. The Rincon Mountain District of Saguaro National Park addressed this natural resource threat with the use of glyphosate-based herbicides (GBHs). In 2010, the Rincon Mountain District initiated an...

Hydrogeologic characterization of the Hualapai Plateau on the western Hualapai Indian Reservation, northwestern Arizona Hydrogeologic characterization of the Hualapai Plateau on the western Hualapai Indian Reservation, northwestern Arizona
This study was developed to assess if groundwater from the western Hualapai Plateau could be used to supply developments in the Grand Canyon West area of the Hualapai Indian Reservation and to collect hydrogeologic data for future use in a numerical groundwater model for the reservation. Ground-based geophysical surveys; existing well, spring, and other hydrogeologic information from...

Reach-scale monitoring and modeling of rivers--Expanding hydraulic data collection beyond the cross section Reach-scale monitoring and modeling of rivers--Expanding hydraulic data collection beyond the cross section
For over 125 years, the U.S. Geological Survey streamgage network has provided important hydrologic information about rivers and streams throughout the Nation. Traditional streamgage methods provide reliable stage and streamflow data but typically only monitor stage at a single location in a river and require frequent calibration streamflow measurements. Direct measurements are not...
