I played a round at Jamesville Beach last week with someone who tried playing out at Clay recently. He said he was very frustrated because he could not find any tees, and ended up just practicing in the fields. I've also heard that at least one basket is heaving. It would not surprise me if you have to wear boots.
Hopefully someone with more first hand information will answer you before tomorrow.
I can, of course, recommend Jamesville Beach and Oxbow Falls as alternatives. JB for long and open, Oxbow for tight and wooded.
(There are guides in our Courses section for both JB and Oxbow with pictures and tips. Like at Jamesville Beach, the tee marker for #18 is missing, but the picture will give you the spot to drive from.)
