It will probably be in the prespawn stages in April. Docks are plentiful and do hold a lot of fish. Watch for docks with rod holders as most of these have some type of planted cover close by. As for available cover, planted brush piles and docks are the predominant sources, with a few lay downs in some areas.
If you find males getting beds ready, the bigger females with be staging in about eight feet and a jig or crawdad color wiggle wart is hard to beat.
As stated above, as we get closer to April, post for a recent report. Most of us regulars will have already spent several days on the water and can offer more timely information at that time.
