Duck hunting in Texas

[Grant48]

How do I find out if its legal to duck hunt from a boat on a particular lake? I've looked all over the Texas Parks & Wildlife website, and cant find anything. I've found the list of public WMA's (Wildlife Management Area), but the list is small (even though the lands are big). I know that it is legal to duck hunt on Lake Fork, but cant find any info saying it (I used to have lakefront property there nextdoor to a boat ramp, and saw duck hunters with duck boats launching all the time). Anybody know? Thanks.
