Fisheries and Fish Passage

We utilize our expertise in aquatic science and engineering disciplines to investigate and solve fish movement and passage issues. Our primary fisheries management services include fish community and spawning surveys, habitat assessments, instream flow studies, and fish entrainment studies.

Our staff have worked on numerous projects for the evaluation and assessment of fisheries, working with our clients at design, permitting and construction phases for numerous fish passage facilities and fish passage structures. Our fisheries management and engineering services assist with the development of technical upstream fishways, downstream passage structures, and nature-like fishways.
