Not sure if your talking about where crabcreek comes into the potholes or where exactly, but here there is no fee. If your talking north of Moses, I have never heard of the fee either, so I think your good to go. My grandparents own a 3/4 stretch of crabcreek north of moses just before the dump and the duck hunting has slowed down significantly since 98'. Used to just slay the ducks, but in the last few years the flight pattern has changed with no corn north of moses hardly. Still get some good shoots everyonce in a while, but no really good shoots like we have in the past(50+ birds). 20 birds now a days is a decent shoot in my book for that area. Still some good jump shooting once the northerns come in about the 15th of november usually is when tey start showing up. Good luck to ya
