Slough fishing is a different animal as there isn’t any structure to “hold fish” per say. IMO your best bet is to sit and wait for schools of fish to roll thru instead of drilling a ton.
We have been in a drought this year in NESD, but that being said, the 3 years before that we had record flooding….it has helped a lot of lakes & sloughs with water levels.
Good luck finding & fishing sloughs….hope you find a little gold mine, and if you do, keep it to yourself so the masses don’t pressure the lake.
