Picking a bass lake for the prespawn/spawn

Bass opener is soon here in Wisconsin and I'm wondering what I should look for when picking out a lake to specifically target prespawn/spawning bass.  Are there any specific characteristics of a lake that make that lake easier to find bass? I've not been very successful in this period and I would like to choose one that makes solving that puzzle a bit easier.  Most lakes around me and in the state are natural.
