I've been dealing with this problem for 20 years now. I have a creek that I have to cross to hunt any of my property. Its about 20 yards wide and is about 1 1/2 feet deep on average. Its in the southern tier and is at the bottom of a big hill. Back in the day before we had 4 wheelers we used to wade across with waders on and leave them on the other side. Then we moved up to 4 wheel drive trucks which worked for a while but sometimes it was too muddy to get out of the creek bottom. One time we hunted a half a day in the pouring rain and went to drive out with a S-10 Blazer. We got to the creek and it was rolling. We all looked at each other and said go for it. (No other way out with a vehicle) The water actually came over the hood and the truck started to float. I was in the back seat jumping up and down so the back wheels would touch the ground and keep us going forward. We will never do that again, that was stupid, and we are lucky we made it across. I checked with the DEC and had a agent meet me down there. To my surprise the creek isn't protected and he suggested getting a dozer in there and widen it where we cross so when it rains it gets wider and not that much deeper. I also found a web site waterdata.usgs.gov that has a monitors in a a lot of creeks and streams that measures depth and is updated every few minutes. I can monitor at my house and if it gets over 2 1/2 feet deep we stay home. It sucks but it has saved us on driving 2 hours for nothing. I would also check with neighbors to see if it any more shallow where it goes threw their property. I have used this option with all my neighbors being cool and letting us cross at their place(if needed) and ride our 4 wheelers slowly back to our property. Sorry about the long story but I know what you're going through. Good luck.
