Well, after about 20 minutes of fighting with it with two fishing nets, I managed to get my lens out of the mud and water. So I came home and put it in clean water. Then I called Canon, and to my surprise they told me it was better to just dry it out the best I could before I sent it in. Reason being was that if they received a lens still full of water they would probably just call it totaled right away.

And since it is a photography forum, here's a picture of it in the sink once it got back home.
