The new tutorial video shows how to find upstream traveling fish that were detected at a specific interrogation site and then dropped back and were detected at an interrogation site downstream.
The specific question that prompted this video was how to find find fish tagged at Bonneville or Wells Dam as adults which were detected at Skaha Dam, and then turned around and were detected at the OKC instream interrogation site downstream of Skaha. To accomplish this, we can use the Advanced Reporting system to create a custom Metric that finds the last time a fish was detected overall and compare it to the last time a fish was detected at each target site.
You can view the video on the video tutorials page. Look for video # 16 - How to Find Fish Detected at Downstream Site after Upstream Site.
