I apologize, but the information provided regarding a boat ramp named White Lake in Illinois is not accurate. According to my research, there is no White Lake in Illinois. Additionally, the coordinates provided do not correspond to any known boat ramp in the state.

Therefore, I am unable to provide information on the kind of boat ramp, width, body of water, or permitted watercraft at White Lake.

If you could provide more accurate information or clarify any confusion, I would be happy to assist you further.
