Dr. Cahoon, Dr. Blank, and he have been working jointly on fish passage research projects for the past 15 years.
Katey Plymesser, PhD, PE
Dr. Plymesser hold a B.S. (Case Western Reserve University ’01) and Ph.D. (MSU ’14) degrees in Civil Engineering. She began her academic career at Montana State University – Billings with a teaching and research tenure-track appointment. Dr. Plymesser joined the Civil Engineering Department at Montana State University in 2016. Her research is focused in ecohydraulics and fish passage with a particular fondness for the application of hydraulic and fluid dynamic models to answer research questions in natural settings. She has worked with the US Fish and Wildlife Service (USFWS) both in Bozeman and at the Region 5 Headquarters in Amherst, MA on fish passage research projects and practical applications and assessments that culminated in the creation of a passage model for American shad in Steeppass (modified Denil) fishways. Her work has been financially supported by the DOE through the Hydro Research Foundation and the USFWS. Dr. Plymesser currently teaches Engineering Mechanics, Statics and Fluid Dynamics. She has been engaging both undergraduate and graduate students in research since she began her own graduate work in 2008. Through her work with the Montana State University chapter of Engineers Without Borders she has been active in promoting student engagement and involvement.
U.S. Fish and Wildlife Service
Research Fishery Biologist, Bozeman Fish Technology Center
Kevin Kappenman is a Research Biologist for the USFWS and will serve as co- investigator and the primary point of contact for the USFWS. He will be responsible for coordinating the use of BFTC physical resources and staff involved in the project, the BFTC budget, and will assist with design of the flume, infrastructure retrofitting process of Denil ladders, review of fish collection permits, health testing requirements, transportation, holding methods, and fish swimming experiments. He is a fishery professional with nearly 30 years of research experience and has published numerous peer reviewed articles and reports. In his position with the USFWS (11 years) his focus is on restoration efforts for sensitive, threatened, and endangered species. He has been involved in a variety of projects promoting native fish passage on small streams and rivers in Montana and as a Research Biologist for the USGS and Columbia River Inter-tribal Fish Commission where he addressed passage concerns on mainstem dams in the Columbia River Basin including work with salmonids, lamprey, and sturgeon.
Bill Rice, PE
Fish Passage Coordinator, Regional Office, Lakewood, CO
Bill Rice is a Fish Passage Engineer for the USFWS and also the regional coordinator for the National Fish Passage Program. He has over 20 years of experience on water resources issues and specializes in assessing, designing and installing fish passage and stream restoration projects. Mr. Rice has designed or been involved as the expert reviewer on hundreds of structures across the country from Alaska, across the West to the East Coast. He has a B.S. (Colorado School of Mines, ’91) in geological engineering and M.S. (Colorado State University, ’98) in watershed science. His work has spanned a range of structures from culverts and bridges to irrigation diversions, rocky ramps and dams.
Engineering Technician, Bozeman Fish Technology Center
Erin Ryan holds a B.S. (Montana State University, ‘13) and M.S. (Colorado State University, ‘15) in Civil Engineering, emphasizing in ecohydraulics and stream restoration. During her undergraduate career, Ms. Ryan was involved in pilot studies for volitional swimming performance trials in an open-channel flume to inform fish passage design. Her graduate work was focused on using computational fluid dynamics in a novel approach to assess the effects of instream structures on upstream fish movement. She is currently an engineering technician with the US Fish and Wildlife Service at the Bozeman Fish Technology Center. In her current position, she conducts research focused on habitat connectivity for aquatic species by evaluating the swimming performance of various fishes and the efficacy of passage structures.
