Water rights and the exercise of those rights have been greatly affected by the enactment of the federal and state Endangered Species Acts. The protection of threatened and endangered species often conflicts with the exercise of existing rights, and complicates the appropriation of new rights. Our firm has extensive experience working with the California Department of Fish and Wildlife, U.S. Fish and Wildlife Service, and the National Marine Fisheries Service. We advise clients with regard to the possible legal implications of proposed activities, and represents clients in negotiations with these agencies. Coordination and active participation with fish agencies can help to resolve issues related to mitigation requirements. Our attorneys have considerable experience with biological opinions, habitat conservation plans, and interacting with resource agencies to negotiate reasonable terms and conditions
