Welcome to the forum, I would look closer to home, PRWR is good but a dog or boat is still a good idea, too many creeks and ditches that might be too deep to get across to retrieve a bird. If you do go, look for the shallower areas with a firm bottom.
Closer to home I would really look for any beaver ponds and with all of this rain recently, fields with water etc. the birds are there, take a ride and look and listen in the woods. Good luck, let us know how things turn out.
