Baring any crazy weather the time frame you mentioned should be good for the type of fishing you guys like to do, on the North end of he lake. The Blacks should be close to, or spawning and the Whites should be staging.

As for the lodging... If you bring a camper keep in mind that most of the campgrounds don't open till April 1st.

You said you were looking south. Might pay to get on the Tn. board and pick their brains.
