Thanks for all this MT.  Very helpful.
I found the same thing this past summer, Trout were more at 30/35 feet than 50.  I've mentioned the Fish Hawk before but I found it a very useful tool not only for getting temperatures (readings every 5 feet up to 300 hundred feet) but also for helping to determine at what depth I'm running.
Needless to say, I'm getting cranked up (badda boom!)) for this spring already.  I'm planning a couple of short trips in June and July and that will mostly be for large and smallmouth.
