Haylie Brown

Haylie is a hydrologist at the Wyoming-Montana Water Science Center based out of Helena, Montana.

Haylie began her career with the USGS in 2022 as a hydrologic technician, and later transitioned into the role of a hydrologist. Her current work focuses on flood frequency analysis, and various sediment projects, including sediment transport and sediment fingerprinting. Her main research interest is fluvial geomorphology.

Education and Certifications

  • BS in Geoscience and a certificate in GIS, University of Montana

  • MS in Earth Science, University of Northern Colorado focusing on fluvial geomorphology

Science and Products

Peak-flow measurement at Flathead River at Flathead, British Columbia

Peak-Flow Frequency Analysis for Selected Montana Streamgages

Peak-flow frequency information is needed for flood-plain mapping, design of highway infrastructure, and many other purposes across Montana. The USGS Wyoming-Montana Water Science Center has an ongoing project working to update peak-flow frequency estimates at USGS streamgages across the state.

Fluvial sediment dynamics in the Shoshone River and tributaries around Willwood Dam, Park County, Wyoming Fluvial sediment dynamics in the Shoshone River and tributaries around Willwood Dam, Park County, Wyoming

Sedimentation affects many of the aging reservoirs in the United States. Dams and water diversions from rivers have been central elements of infrastructure supporting agricultural irrigation in the arid and semiarid regions of the Western United States for more than a century. The Willwood Irrigation District diversion dam (hereafter referred to as “Willwood Dam”) in Park County, Wyoming...
