Winter Bassin'

Ice has been off for several weeks BUT the water is still really cold. Havent taken temps but Brrrrrrrrrrrrrr! Today is the first day over 50 in forever and I'm going fishing! A few questions...

1. I'll be downsizing for sure and slowing down to a crawl but I wont catch 'em if I'm not on 'em. At about what water temps are the bass going to move to shallower cover with deep water access?

2. Should I assume the bass are deep right now since the water is so cold still?

3. Is it possible to get a reaction strike from a bass in water with temps in the 50's when finesse baits arent working? (using a rattle trap or the like?)

Please give us your best winter and cold water bass fishing tips. Times of day (i like to let the water warm up a little) most successful places you fish in cold water (windy points, deep structure, etc)

Thanks!
