Last week, I received the subject report from a reliable angler.
They were channel cats, & he caught quite few: 1 - 4 lbs., & had one on, estimated @ 10 lbs., but lost it.
Word got out, & 20 + anglers were there the next day. He witnessed an unattended rod get pulled / launched into the water, by probably a 5 lb. + channel.

A number of years ago, @ night on the Delaware R., I witnessed large numbers of channels @ the surface, sipping on emerging insects. I couldn’t get them to hit anything I had.
