It depends. This is also a catering venue and sometimes the whole facility is closed for an event. Call them and check and also events in the Park and weather can affect them.
I'm not sure I made a reservation a month and a half in advance they were already very booked so they gave me 9:00 p.m. When I arrived they did not have it in their books, but I showed it to them on my confirmation email. They did manage to get us a water side table one back from the front row. It was nice. That was Sunday July 11th. I believe that is the last time they would take a reservation for the night.
