Guys, the question asked was wither we could help or not. Yes.
However, without having any idea what is planted where, what the scale is to your map, depth of water, nut trees? crops? My help can only be limited.
Going strictly by the contours and the water shown, existing roadways, and guessing scale based upon roadway width....I believe points A, B, C , show promise, due to the natural boundary of the waterway, and the steepness of the slope. It should produce a decent funnel.
I would head for C myself, due to the bend in the river will slowdown and shallow the water. More likelyhood of a crossing there. Between the funnel and the crossing (always assuming the deer have some reason /food/bedding) to want to cross.
I'd put a climber up just inside of that point, or if no suitable trees, a pop-up blind brushed in.
Best method IS boots on the ground, but I'm assuming distance or access is problematic. I also use GPS TOPO to pick out likely spots, but knowing what grows there makes a big difference.
The only real difference between a good tracker and a bad tracker is observation. All the same data is present for both. The rest is understanding what you are seeing.
