I was wondering wheir everyone fished. I have for the past 25 years or so allways fished the south end off of mercer island below I-90. This year I have a new boat and moore it in lake union and fished between the two bridges. In the past fishing the south end we went deep 70 - 90 feet. this year deepest I fished was 60 feet but marked allmost all of the fish on my fish finder at 40 -60 feet with most of those being at 40-43. I was trying to figure this out . Only thing I could come up with is they are either following a thermal layer or haven't yet made the trek to deeper water as they have just made the right turn out of mount lake in shallow water and headed to the south and just havent headed down yet.
