I'm going up to Pollock next month and I'm looking for a contour map of the lake near Pollock. I'm hoping someone can point me in the direction of map. I don't feel like buying the Navionics app for one trip, since I do most of my fishing in Nebraska and I can get those maps for free. I was up there last year and I thought we were set up on a decent spot with some depth changes, but it was mostly guess work, and we didn't have a lot of success.
