Cory currently serves as the Deputy Program Coordinator for the Groundwater and Streamflow Information Program which provides impartial, timely, rigorous, and relevant data for short- and long-term water decisions by stakeholders across the United States.
A former Director (2018-2021) and Surveillance Section Chief (2005-2018) of the Utah Water Science Center and Field Office Chief (2003-2005) of the Yuma, AZ, office, Cory has been involved in USGS data collection and science since 1995. He has led data and science programs and managed staff in Arizona and Utah. Cory has led data collection and research activities on Great Salt Lake (GSL), and was a member of several multi-agency technical teams related to GSL issues.

In July 2021, the southern portion of the Great Salt Lake reached a new historic low, with average daily water levels dropping about an inch below the previous record set in 1963, according to U.S. Geological Survey information collected at the SaltAir gage. The lake continued to recede until October 2021, and in July 2022, the level of the lake fell below the October 2021 record low.
Urban Waters Federal Partnership Cooperative Matching Funds Projects
The Urban Waters Federal Partnership reconnects urban communities with their waterways by improving coordination among federal agencies, particularly those communities that have been disproportionately impacted by pollution or economic distress. The UWFP draws upon Environmental Justice principles—the idea that all people, regardless of race, religion, national origin, or economic station, deserve...
Streamflow Information Program
The U.S. Geological Survey (USGS) operates and maintains a national network of about 8,000 streamgages (2018) to provide long-term, accurate, and unbiased streamflow information (often called discharge) to meet the multiple needs of many diverse users. Streamflow information is fundamental to national and local economic well-being, protection of life and property, and efficient and effective...
What is a streamgage?
Information on the flow of rivers and streams is a vital national asset that safeguuards lives, protects property, and ensures adequate water supplies for the future. The USGS operates a network of more than 9,000 streamgages nationwide with more than 150 in Utah, but how does a streamgage work? Dee Lurry of the Texas Water Science Center answers that question.

Calculating salt loads to Great Salt Lake and the associated uncertainties for water year 2013; updating a 48 year old standard
Effective management of surface waters requires a robust understanding of spatiotemporal constituent loadings from upstream sources and the uncertainty associated with these estimates. We compared the total dissolved solids loading into the Great Salt Lake (GSL) for water year 2013 with estimates of previously sampled periods in the early 1960s.We also provide updated results on GSL loading, quant

Density-stratified flow events in Great Salt Lake, Utah, USA: implications for mercury and salinity cycling
Density stratification in saline and hypersaline water bodies from throughout the world can have large impacts on the internal cycling and loading of salinity, nutrients, and trace elements. High temporal resolution hydroacoustic and physical/chemical data were collected at two sites in Great Salt Lake (GSL), a saline lake in the western USA, to understand how density stratification may influence

Monitoring change in Great Salt Lake
Despite the ecological and economic importance of Great Salt Lake, only limited water quality monitoring has occurred historically. To change this, new monitoring stations and networks—gauges of lake level height and rate of inflow, moored buoys, and multiple lake-bottom sensors—will provide important information that can be used to make informed decisions regarding future management of the Great

Runoff conditions in Utah for water year 2011
In May 2011, the snowpack conditions in the mountains of central and northern Utah had emergency planners and water managers preparing for levels of runoff similar to the record year of 1983. The SNOwpack TELemetry (SNOTEL) records from the Natural Resources Conservation Service (NRCS) reported that the amount of water contained in the snowpack in May 2011 was greater than it was in either May of

Application of Geographic Information System Methods to Identify Areas Yielding Water that will be Replaced by Water from the Colorado River in the Vidal and Chemehuevi Areas, California, and the Mohave Mesa Area, Arizona
Relations between the elevation of the static water level in wells and the elevation of the accounting surface within the Colorado River aquifer in the vicinity of Vidal, California, the Chemehuevi Indian Reservation, California, and on Mohave Mesa, Arizona, were used to determine which wells outside the flood plain of the Colorado River are presumed to yield water that will be replaced by water f

Characterization of hydraulic conductivity of the alluvium and basin fill, Pinal Creek Basin near Globe, Arizona
Acidic waters containing elevated concentrations of dissolved metals have contaminated the regional aquifer in the Pinal Creek Basin, which is in Gila County, Arizona, about 100 kilometers east of Phoenix. The aquifer is made up of two geologic units: unconsolidated stream alluvium and consolidated basin fill. To better understand how contaminants are transported through these units, a better unde

In-situ alteration of minerals by acidic ground water resulting from mining activities: Preliminary evaluation of method
The chemical composition of the Cu-mining-related acidic ground water (pH ∼ 3.5 to near neutral) in Pinal Creek Basin, Arizona has been monitored since 1980. In-situ experiments are planned using alluvial sediments placed in the ground-water flow path to measure changes in mineral and chemical composition and changes in dissolution rates of subsurface alluvial sediments. The test results should he
