Spatial digital database for the geology of the San PedroRiver basin in Cochise, Gila, Graham, Pima, and PinalCounties, Arizona
This open-file report is a digital representation of theDickinson (1993, 1998, 2000) remapping of the post-Mid-Miocene Quiburis Formation in southeastern Arizona. Itdelineates constituent facies of the Formation throughoutthe San Pedro trough.
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...
A GPS survey was conducted on July 10, 2018, to document the CSA pin elevations and cross section geometry at the CSA sensor locations at CSA 09471587 - Dragoon Wash above San Pedro River at St David, AZ, and CSA 09471588 - San Pedro River below Dragoon Wash at St David, AZ. Three CSA pin elevations and cross sections were surveyed at CSA 09471587 - Dragoon Wash above San Pedro River at St David, AZ; and four CSA pin elevations and cross sections were surveyed at CSA 09471588 - San Pedro River below Dragoon Wash at St David, AZ.
A GPS survey was conducted on June 12, 2019, to document the cross section geometry at the streamgage 09471580 - San Pedro River at St David, AZ, and CSA pin elevations and cross section geometry at the CSA sensor locations at CSA 09471588 - San Pedro River below Dragoon Wash at St David, AZ. One cross section was surveyed at streamgage 09471580 - San Pedro River at St David, AZ; and four CSA pin elevations and cross sections were surveyed at CSA 09471588 - San Pedro River below Dragoon Wash at St David, AZ.
Migrating Bird Survey Data Along the San Pedro River and its Tributaries, Southeastern Arizona, 1989-1994
Data files in this data series represent migrating bird count and habitat information collected during 1989, 1991, 1993, and 1994 field seasons at 13 riparian sites along the San Pedro River and its tributaries in southeastern Arizona, USA. At each site observations were made at up to 20 points, separated by 100 m arrayed along the riparian zone. Observation periods started at 20 minutes after sunrise, lasted for 7 minutes at each point and were completed within 4 hours. Bird detection and species identification were based on visual sighting, song, and call. Recorded observations were the number of individuals of each detected species detected using each detection method at each point and site within specified distance...
This database contains physical and biological data for the Lower Colorado River Basin. The metrics include information on geology, hydrology, landcover, stewardship, topography, soil types and characteristics, stream characteristics, connectivity, and watershed position (information on where a stream segment or catchment is located in relationship to other segments or catchments; e.g. distance from a catchment to the mouth of the Colorado River, Shreve Link). In addition, there is a table with predicted probability of species occurrence for the connected stream segments and tables with the data used in those models. The species distribution models were completed for 18 native fish species and 21 non-native fish...
Riparian vegetation provides crucial habitat for wildlife and is a high conservation priority for land managers throughout the Southwest but a central scientific challenge is to generate quantitative predictions of how changes in water availability will affect the amount and quality of riparian wildlife habitat. Researchers will study areas that have long-term datasets available (i.e., hydrological, geomorphological, biological), that characterize a broad range of riparian conditions found in the Southwest. Building on recently developed models funded by the USGS National Climate Change and Wildlife Science Center (NCCWSC), this work will link various hydrologic, geomorphic and habitat models to better understand...
Final Report: Predicting Effects of Climate Change on Riparian Obligate Species in the Southwestern United States
ABSTRACT: The Lower Colorado River and Rio Grande Basins are home to many riparian vertebrate species with different degrees of rarity. In our study, we focused on two species of birds and two species of gartersnakes that are associated with riparian areas: the Yellow-breasted Chat (Icteria virens), the Yellow Warbler (Setophaga petechia), the Northern Mexican Gartersnake (Thamnophis eques megalops) and the Narrow-headed Gartersnake (T. rufipunctatus). While the extent of distributions of these species is relatively large, they are often patchily distributed in populations that are small; in addition, both gartersnake species are listed as threatened under the Endangered Species Act. Aside from detrimental effects...
The dataset contains data from a GPS survey conducted after a flow event on November 29, 2019, at the USGS streamgage 09471580 - San Pedro River at St David, AZ. The survey, conducted on December 5, 2019, documents cross section geometry and high-water marks from the flow event in the reach downstream from the gage. One CSA pin elevation at CSA 09471588 - San Pedro River below Dragoon Wash at St David, AZ, was also surveyed. The other three CSA sensors at 09471588 were destroyed during the November 29, 2019, flow event.
