Surface water temps ranged from 44F to 46F when we showed up last Wed. We saw 48F in the narrows when we left yesterday. I was worried my fish finder was reading high but it was confirmed against 3 other units and the IFW man when he came to visit. Still not a very fishy trip so it's definitely early. A few 6lb lakers were caught and a good amount of short salmon. Only two keeper salmon for 5 days of trolling- brutally slow but still a fun trip. I love that lake, it's so undeveloped.
