Whitefish in Battle are tough to catch. Big Fish. Not very many of them.
Wirewraps are so/so. Wetaskwin's, Spoons and Wedding Bells usually a better bet. Use bigger tackle than you would at Pigeon. Bite is usually at first light. They are scattered so tough to find the hot spots. There are flats along the weed lines on the N and NE side. I'd start there. Walking out of course
Surprised by how little snow there is on Battle. From your pic it only looks like an inch. Would have expected over a foot based on what Dad had to push out of the yard last week.
When was it you said you went through?
