While I have to admit that there doesn't seem to be a lot of water slides, I would look at the brighter sides of what the park should offer. It's a pretty small park with a few slides, what seems to be an adequately long and deep lazy river, and a big rock building with who-knows-what inside (Well, I don't know what's inside).

The place looks pretty nice from a local standpoint, and would seem worth a stop if I was traveling near the area (imo).

Are those photos yours?
