Small lake Help!

I am fishing a lake that is roughly 15 acres and the depth every where is 3 to 4 feet. There are bluegill crappie and bass in it. Where would crappie hold in a setup like this points, structure, weeds etc. is there something specific that I should be looking for that would hold a higher percentage of catching crappie.

If it’s that shallow there is some current or springs. Use caution, but try areas near there.
