Yes we keep ducks to the end of the season and ever after it closes you will still see ducks. The biggest problem we have is the drought has the ponds so low and they are all frozen. I suggest that you hunt a creek, river or a lake. Where are you at and I can try to offer a suggestion or two? I am in Marshfield just outside of Springfield.
I saw that you are headed to hunt Stockton. Are you going on Sons creek or Turnback? The lake is really low and starting to feeze in the shallows. The divers working the points fairly well this time of the year and rafting in the middle. Don't ingore them or they will fly by before you know it! The mallards are spotty right now but, gadwall are everywhere in the lakes and rivers. There are also a few GWT around. Lesser canadas are also making the first wave or two around here. Stockton also has a lot of resident greaters in the 10 to 13 pound range and they make a hell of a splash from 30 feet up!!! If you don't have any luck at Stockton, Table Rock can be good at times and this happens to be a good time from what some of my friends are saying, but I haven't been there this year to say for sure! Good luck and don't shoot 'em all. We still have three weeks left and I need a few more birds to get me through the summer!
