Don't know if it'll help but I tried for burbs a couple weeks ago at CVR.
Somewhere right around
here, with the bath maps thought it was a decent spot some where around 25' deep. Got skunked, fished from roughly 7 pm to midnight.
Almost certainly my own fault, I have no idea what I'm doing when it comes to ice fishing or fishing in general. Got the just of what needs to be done and still learning.
Be out there again this weekend and next I imagine. Going to try a little further south
