2008 High-Flow Experiment at Glen Canyon Dam Benefits Colorado River Resources in Grand Canyon National Park [More info]
Scientists studied whether high flows could be used to rebuild sandbars, create nearshore habitat for the endangered humpback chub, and help other resources such as archaeological sites, rainbow trout, aquatic food availability, and riverside vegetation.
PDF A dryland river transformed--the Little Colorado, 1936-2010 [More info]
We mapped substantial migration of the river channel between the City of Winslow and the Navajo Nation community of Leupp; in a human lifetime the river has moved more than a mile across its valley floor.
PDF An experiment to control nonnative fish in the Colorado River, Grand Canyon, Arizona [More info]
We removed non-native fish from a section of the river and the endangered native species humpback chub increased in abundance. But it is not yet clear that decreased competition explains the rebound in population.
An interpretation of the 1977 Airborne Electromagnetic (AEM) survey, Fort Huachuca vicinity, Cochise County, Arizona [More info]
Complex report on the interpretation of aeromagnetic data to study hydrogeology of the San Pedro basin, Cochise County, Arizona determining geologic structure, basin fill and depth to water. Online version of a CD-ROM publication.
PDF Assessment of Moderate- and High-Temperature Geothermal Resources of the United States [More info]
The electric power generation potential from identified geothermal systems is 9,057 Megawattselectric (MWe), distributed over 13 states. Undiscovered resources are estimated to provide an additional 30,033 MWe.
Biomarker Benchmarks: Reproductive and Endocrine Biomarkers in Largemouth Bass and Common Carp from United States Waters [More info]
Describes a national reconnaissance study of reproductive health in two species of fish across the US. More than 2,200 common carp and 650 largemouth bass were collected at 119 rivers and streams.
PDF Breccia-pipe uranium mining in northern Arizona; estimate of resources and assessment of historical effects [More info]
Estimates of uranium resources affected by land withdrawal, effects of previous breccia-pipe mining, water-chemistry data for streams and springs, and potential biological pathways of exposure to uranium and associated contaminants.
Data for giant constrictors - Biological management profiles and an establishment risk assessment for nine large species of pythons, anacondas, and the boa constrictor [More info]
Locations for nine species of large constrictors, from published sources, along with monthly precipitation and average monthly temperature for those locations. Shapefiles for each snake species studied.
