Salmon Numbers Down

Figures recorded as of Sunday, Nov. 18, show the Stanislaus River fall-run salmon migration is at 4,161 salmon. For comparison, the season total was 6,726 salmon at this time last year. Salmon are counted at the Stanislaus River weir with the help of an automated fish counter called the Riverwatcher. This device uses an infrared scanner to count and measure each fish that passes through the weir, and also records a video. With the help of the Riverwatcher, officials are able to track the salmon migration down to each individual fish.

Funding for salmon monitoring at the Stanislaus weir is provided by the Oakdale Irrigation District, South San Joaquin Irrigation District, and Tri-Dam. Data collection is conducted by FISHBIO. For more information, visit
