Harrison can get alot of birds on it at times. Most of the time the water line is so low that you can't hunt out of a boat/blind combo because all of the cover is 30 to 50 feet behind you. Also if you get back towards the dam or back to the outlet keep aware of the wind, the rollers can get REAL NASTY in the canyon when the wind get howling.
As for birds, I can tell you that on Sunday the 30th there was nothing on the water and only a few in the air goin' high and fast. My buddy that is a guide decided to give it a try since he had the day off and the water is supposed to still be up, and they got skunked. Three guys and not a one of them got to shoot all day. I was at Ennis above the lake on the Madison and we were 2 birds short of limiting out by 9:30 with three guys. Needless to say....when we met my buddy, the guide, and his group in Norris for a cold one he was pretty quiet. But not me
. I might not get payed to take the people hunting but it sure is nice when you kill more birds than those that do.
