Hey Bo, from Winnipeg as well. Never fished Westhawk for Lakers but used to live up north(Flin Flon) and caught ours during the day. We caught anywhere from 25 to 100 feet using Sucker, Whitefish, Smelt and chummed them in. Sonar helps, fish the whole water column. Try the drop and fast reel-up when things get slow. We could see them down the hole chasing up from about 30 feet on Athapap....
Good luck.....
