Once pressured the birds that dont leave altogether get in a pattern of spending most of the day on the duck lake reserve to rest and then feeding on the lake bed at night. Most of the puddle ducks use it as their refuge while most of the divers use center of the lake as their refuge. I know some foks might gripe about it but I think without it you would be seeing even less birds than you already do.
I really wish something would be done to reduce pressure on the lake. Shell limits, reduced hunting times, reduced access, better enforcement of current laws, something.
Ive heard you mention that the only time the hunting is any good is opening days. This is a direct result of the massive pressure on the birds out there. People sit in their blinds all day long, shoot 3-4 boxes of shells per person at anything inside 75 yards when they have birds, and then cant figure out why they dont have any birds outside of opening weekends. Ive hunted the north end enough to know a lot of people up there do what they want when it comes to game laws and none of it is doing themselves any favors in the long run.
