Channel 3 did a nice story on salmon passing the fish ladder at the Lincoln Gauging Station behind Lincoln, as well as the video fish counting program by Friends of Auburn Ravine. The fish are counted by volunteers as the fish pass over a white plate on the bottom of the stream. The white plate makes it easier to see the salmon which otherwise are naturally camouflaged from above against the stream bed. You can see the full story at the link below:
