Willard bay depth map?

[Gone Forever]

As Pat can tell you, there really is no great variation in bottom contour at Willard anyway. It's basically a big flat, with the deepest part near the southwest corner, but no significant "structure" elsewhere except for the remains of old roads and a few rock piles that sometimes become islands in low water times.

I have asked Willard fish why they prefer certain spots one day and somewhere else tomorrow, but they never answer. That is, on the rare occasion when I can find one to ask.

Rocky has it right.  Imagine, if you will, the building of Willard.  Pretty much dozers pushing up a dike to hold the water in.  
For structure you have some wind-rows created by the dozers, some old roads from the dump trucks and a few small piles of gravel.
The wipers follow the food. In days of old I used to "run and gun" for them.  Sitting near the middle with bino's watching for bird action. Then race over there as fast as I could and drift into the fray casting like crazy.
