About OneFish Engineering
OneFish focuses on the interaction of water use and river habitat. We are based in Colorado and work throughout the Mountain West region. We have completed projects in Colorado, Wyoming, Utah and Montana. OneFish specializes in the fields of fish passage, fish screening, and hydrologic measurements.
Fish Passage is primarily focused on allowing fish to move upstream past barriers in the river, reconnecting populations in different sections of the river. In some cases, resource professionals may want to introduce intentional barriers to passage in order to protect native fish from invasive species.
Fish Screening is designed to prevent fish from leaving the river with diverted water, most commonly into irrigation canals. Fish that leave the river are often lost to the system, and fish screens can prevent this loss to improve fishery health.
Hydrologic Measurements are more complex and difficult than most people appreciate. Accurately and reliably measuring depths, velocities, flows and other critical data require sophisticated equipment and the expertise to apply it to the specific goals of any given project.
The OneFish Engineering Team
Suzanne Huhta, P.E.
Suzanne Huhta, P.E., has a master’s degree in structural engineering. While working as a bridge design engineer, she was first exposed to fish passage engineering and subsequently started work for the Oregon Department of Fish and Wildlife (ODFW) as a fish passage engineer. At ODFW she designed multiple types of fish screens and upstream passage projects, and reviewed scores of fish passage and fish screening projects. She understands which techniques are most appropriate to a given situation, and each technique’s strengths and limitations. Suzanne founded OneFish Engineering in 2009, and has gained a broad experience in applying fish passage techniques to the particular challenges of the mountain west region. Over her years of experience Suzanne has worked extensively with biologists, state and federal agencies, irrigators, power companies, municipalities, and non-profit organizations. Successful fish passage projects require the careful merging of biology and engineering. Suzanne understands the needs and concerns of each stakeholder, and works diligently to be sure the solution addresses the complete needs of the project.
Craig Huhta worked the first 20 years of his career designing and operating specialized instrumentation for the measurement of water. He has designed some of the most successful hydrology instruments on the market, including the FlowTracker, the Argonaut-SW, the SonTek-IQ, and portions of the RiverSurveyor ADCP. His specialty is the complex signal processing, data analysis, and hydraulic modeling required by sophisticated water measurement instrumentation. He has made measurements at sites from 1 inch to 3 miles deep, and in locations from the desert southwest to the waters around Antarctica. At OneFish, Craig applies his experience to the needs of water measurement and modeling in streams and irrigation canals. He conducts instream flow studies, irrigation efficiency studies, and has installed permanent gauging sites including remote data access via a web service hosted by OneFish. He has a thorough understanding of the complexities associated with accurate flow measurements, and how these can be used to support both the natural resource and irrigation communities.
OneFish regularly partners with a variety of other firms to provide the expertise needed to successfully complete a range of projects. We have established relationships with civil engineering firms, stream restoration professionals, structural engineers, geotechnical engineers, and surveyors. On larger projects, OneFish can act as either the leading firm or a subcontractor as needed to best serve the client's needs. Working with OneFish, the client gets the fast response and personal attention of a small firm while accessing the expertise needed to complete the project successfully.
