Abstract: Steelhead (Oncorhynchus mykiss) in the Central California Coast (CCC) Distinct Population Segment (formerly Evolutionarily Significant Unit) were listed as threatened by the National Marine Fisheries Service (NMFS) in 1997. Due to their protected status, the Santa Clara Valley Water District (SCVWD) decided to implement a noninvasive means of documenting steelhead passage through the fishways. The equipment chosen to accomplish the task was the Vaki Riverwatcher (Vaki), a computer-based fish counter which employs scanner plates and a digital camera to capture videos and silhouette images of fish as they pass between the plates. The Vaki provides information on the occurrence and timing of fish migration both upstream and downstream of the counter. Table of Contents: Partial contents: Appendix A. Sample silhouettes and video images.
