Since then, collaborative efforts have occurred among many local, State, Tribal, and Federal agencies.
In Spring 2025, the Watershed Protection District / Water Resources Department implemented a Community Science Spawner Observation Program to monitor the Clear Lake hitch, a species of special concern endemic to the Clear Lake watershed. Following a successful second year of the program, community science observations continue to provide valuable information on Clear Lake hitch spawning activity and relative population trends. This ongoing effort strengthens our understanding of the species and helps inform long-term conservation and management strategies.
A total of 33 monitoring sites were established across key tributaries throughout the Clear Lake watershed. These sites were observed weekly for 10 consecutive weeks, beginning March 9, 2026. Twenty-nine trained community volunteers participated in this effort. Volunteers received instruction on fish identification—including both in-person and field training components—a...
