Dr. Blank holds a B.S. (University of Wisconsin, ’94) in geological engineering, and a M.S. (MSU ’02) and Ph.D. (MSU ’08) in civil engineering.  He has over 20 years of experience conducting both academic studies and consulting activities on water resource issues.  He is currently a research scientist and assistant research professor at the Western Transportation Institute and the Civil Engineering Department at Montana State University, and does water resource consulting with Restoration Engineering, LLC, a private consulting firm.  He is co-principal investigator of a fish passage and swimming research facility formed through a partnership with the United States Fish and Wildlife Service, and has been investigating fish passage and aquatic connectivity issues for over a decade.  He teaches applied fluid mechanics and engineering hydraulics at MSU.  Through both research and consulting activities, Dr. Blank has been involved with the assessment, design, or review of hundreds of hydraulic structures in rivers and streams across the country and in Canada.   This work spans the range of structures from small culverts on gravel roads, to irrigation diversions, to large hydropower dams on major rivers such as Albeni Falls Dam on the Pend Oreille River in Idaho, and Conowingo Dam on the Susquehanna River in Maryland.

Faculty Website

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.

Al Zale, PhD

Professor, Department of Ecology

Unit Leader, USGS Montana Cooperative Fishery Research Unit

zale@montana.edu

Dr. Zale received degrees in fisheries science from the University of Massachusetts-Amherst (BS), Virginia Tech (MS), and the University of Florida (PhD).  He worked in Oklahoma before coming to MSU in 1994, where he leads, coordinates, and administers an applied fisheries research program addressing topics and issues of concern to the State of Montana and the U.S. Department of the Interior. His research interests are therefore wide ranging, including restoration of native fishes, fish entrainment and passage at irrigation diversions, thermal ecology, population dynamics and effects of nonnative fishes, and effects of land-use practices on fisheries. His earlier research focused on game fish management, fisheries in regulated rivers, whirling disease, and molluscs. He teaches a graduate course on the human dimensions of fish and wildlife management and is obsessive about technical writing.

Bozeman Fish Technology Center Website

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.
