Winter Wakeboarding in Austin, TX Area - Possible?

I am thinking of heading south over X-Mas break to visit my sister in Austin, TX.

My kids would like to try to get in some wakeboarding while we are down there. Is it possible this time of year?

We would not be taking our boat, so if I could find a school or something that would be great. Maybe even a cable park??

Any suggestions?

Thanks!
