End of august can be good and bad best bet is to keep a close eye on fishing reports for location u plan to fish. Depends on weather really normally in my experience if u are planning on three day trip come third week in august just in case and u should have fish in 100 to 120 fow they should be staging up good by then in big pods flasher flys work good j plugs and meat rigs if there are pods on bait u can really put them in the box but be sure to keep eye on fishing report good luck
