The Canal run has been relatively poor this year. Despite what you might read from one guy on FFSW. As of 5/6, the fish counter was tallying 20,000, according to the herring agent.
I was down there today. There were just a few in each of the lower pools--maybe 50-70 in the second one at the top of the first fish ladder--and about 20 grouped up at the top of the chute along Rte 6, waiting to go under the road. There was absolutely no sign of any herring in the Canal itself
I've yet to see a fish taken at the Run, let alone catch one myself, altho I'm sure there must have been a few taken there.
There's a pick of keepers in other places along the Canal, tho.
