Diving for antiques in MN

[shamre]

Does anyone know of any local lakes that they have dived and found old antique bottles, old bones, other misc treasures in? I am particularly interested in local twin cities lakes with hard sandy or rocky bottoms. I have dove theodore wirth which is suppossed to have old antique bottles in it. But all i found is mud. 

There is a new dive season starting up and i hope to have a list of other local lakes that i can search for treasures at.

Is white bear lake good for this type of diving?
