I agree that scouting the day before is key. We hunted there last week and shot two limits The key was the homework we did the day before. We got there Friday afternoon, used binoculars from the opposite side of the lake to see where the birds wanted to be, then set up in the dark Friday night. This tip might be helpful for this late in the season: The birds are kind of gun shy. They have been shot at a lot, particularly on the refuges, from the tule line. We as hunters obviously flock there because that is the best/easiest cover to hide in, but gun-shy ducks, and particularly puddle ducks will want to be in wide-open, shallow places. I built a portable blind out of pvc, burlap and army camo mesh. We fortified it heavily with tules the night before and put it right in the middle of a bare shoreline that had some taller grass. I think the ducks wanted to be there because there is no cover for predators (hunters) to sneak up on them. The blind stood out like a sore thumb to hunters but the ducks seemed oblivious. Lay out blinds would have been better but we had two kids we wanted to hide as well. Good luck!
