Hi
Got this from TWRA's site. Keep it in mind when fishing at the dam.
CHEROKEE RESERVOIR
A closed fishing zone will be in effect from July 15 through September 15. This zone is enclosed by lines from the boat ramp at the south end of the dam across the lake to Point 2, from Point 2 to Point 3, and from Point 3 back across the lake to the TWRA boat ramp at the north end of the dam. All bank fishing will be open and the coves along the southeast shoreline will be open to boat fishing, but no fishing for any species will be allowed in the described zone from July 15 through September 15.
Here's a link to a map outlining the no fishing zone.

Just wanted to make sure you didn't have any trouble with the TWRA since this starts on Saturday.
Good Luck!
