Recent licensing proceedings under the Federal Energy Regulatory Commission (FERC) have required that fish entrainment studies by conducted at several hydroelectric projects throughout the U.S. These investigations are labor intensive and logistically-complex and usually require unique innovations that draw on knowledge of fisheries sampling gear, hydraulics, engineering and biology. A fish entrainment study was conducted at the 6-MW Feeder Dam Project, which required detailed planning and problem solving by a study team comprised of engineers and fishery biologists. Requirements that were encountered by the study team included resource agency directives regarding study design and methodologies, constraints imposed by the site layout and by the project owner, and the FERC directive that the study be completed within an 18-month window. The integrated team of biologists and engineers designed work platforms, a net frame handling system that utilized electric hoists, and inexpensive live cars that allowed for the live capture of fish even during high debris-loading periods. A computerized, automatic data collection system was developed to record station operational data. On-site fish holding systems were developed for live fish required for the net efficiency and entrainment mortality tests. Through the close working relationship of the biologists and engineers, and with an open dialogue with the resource agencies, solutions were developed for problems that arose, and the study was completed according to the FERC schedule.
