Detroit Lakes/ Otter Tail Area Diving?

[spitfire_er]

A few of us were thinking about going diving on friday (4-28) in the Detroit Lake/ Otter Tail county area. I was going to see if anyone knew of any good lakes to dive, or any underwater features that might be fun to dive. Anything that is sunken or unique would be great. I have dove a few lakes in the area.... but nothing much to see besides fish and weeds.
