Using an Optimization Model to Select Fish Passage Barriers for Remediation

Workshop Coordinators:
Lisa DeBruyckere, Fish Passage Forum
Ross Taylor, Ross Taylor and Associates

The California Fish Passage Forum has been developing FISHPass, a decision support tool that assists in identifying cost-efficient mitigation actions to maximize the amount of accessible habitat above barriers, using a mixed integer linear programming formulation. The tool integrates information on barrier passability, potential habitat, and mitigation cost, and accounts for spatial structure of barrier networks as well as interactive effects of mitigation decision on longitudinal connectivity. This workshop focuses on testing FISHPass in a variety of watersheds along the coast of California, giving fish passage practitioners, and others involved in fish passage barrier remediation, an opportunity to test the model in a variety of watersheds. The goal of the workshop is to familiarize fish passage practitioners with FISHPass and its utility in optimizing fish passage barriers for remediation.
