Ashley is a physical scientist for the Wyoming-Montana Water Science Center in Helena, Montana where she investigates water quality dynamics and its effects on the biological structure of streams and lakes.
She began her career with the USGS in 2016 as a pathway’s student in Austin, TX working in the lab analyzing glyphosate samples for the Regional Stream Quality Assessment (RSQA) and studying groundwater quality as a part of the National Water-Quality Assessment Program (NAWQA). After graduating with her MS, she took a position as a physical scientist with the Lower Mississippi-Gulf Water Science Center in Ruston, LA. For the next several years she investigated groundwater use, availability, and water quality as a part of the Mississippi Alluvial Plain Regional Availability Study and the Integrated Water Availability Assessment of the Chicot Aquifer System in southwestern Louisiana.

Sampling and analysis plan for the Koocanusa Reservoir and upper Kootenai River, Montana, water-quality monitoring program, 2021In 2021, the U.S. Geological Survey will collect water-quality samples and environmental data from 3 sites in Koocanusa Reservoir and from 1 site in the Kootenai River. The transboundary Koocanusa Reservoir is in southeastern British Columbia, Canada, and northwestern Montana, United States, and was formed with the construction of Libby Dam on the Kootenai River 26 kilometers upstream from Libby,AuthorsSara L.

Long-Term Surface-Water Monitoring in the Upper Clark Fork River BasinThe U.S. Geological Survey (USGS) has collected water-quality samples from selected stream sites upstream from Missoula since 1985.
Quality Assurance of Water-Level Records from Wells in the Chicot aquifer system in southwestern Louisiana Department of Natural Resources' Stategic Online Natural Resources Information System (SONRIS)The Louisiana Department of Natural Resources’ (LaDNR) Strategic Online Natural Resources Information System (SONRIS) is a repository for recent (1930–present) well information that includes date of completion, well construction, geology, and water level. Well information is provided by the well drillers during the permitting process and is updated regularly by LaDNR. This data set consists of wel
Groundwater Quality Data of the Chicot aquifer systemThis dataset contains digitized groundwater quality data from 435 wells that are screened in the Chicot aquifer system. Reported values of interest included specific conductance, total dissolved solids, and chloride (Cl) concentration; other parameters and major/trace element concentrations were included if reported. Values listed as "NA" or "-9999" represent data that was not reported in the phys
Chicot Aquifer System Extent in Southwestern Louisiana, October 2020The Chicot aquifer system underlies an area of approximately 9,500 mi2 in southwestern Louisiana and is located within the Gulf Coastal Plain physiographic province. The region includes all or parts of 15 parishes -- Vernon, Rapides, Evangeline, Allen, Beauregard, Calcasieu, Jefferson Davis, Acadia, St. Landry, Lafayette, St. Martin, Cameron, Iberia, Vermilion, and St. Mary. The Chicot aquifer sys
Stream habitat relations of the Yellowcheek Darter (Etheostoma moorei) among four forks of the Little Red River in ArkansasThe Yellowcheek darter (YCD), Nothonotus moorei (Robison and Buchanan 2020), is endemic to the headwater tributaries (a.k.a. ‘forks’) of Little Red River system (South Fork, SF; Middle Fork, MF; Archey Fork, AF; and Beech Fork, BF) in north central Arkansas. Large portions of critical stream habitat in each stream fork were inundated in 1964 with the construction of Greers Ferry Dam, and the YCD i
