I'd try emailing one of the biologists. Every time I've emailed one of them, I've gotten a reply. That may or may not get you the information you want, but it's a good place to start. Here's where you can find the biologists:

The few times that I have emailed KDFWR I have gotten a response. Had some good email conversations with some of the biologists over the years. When I've run into them on the lakes they have had no problems providing info. Try the link that RoadToad provided and start there.
