Fishing License
You need a Texas fishing license to fish most public waters in Denton County
Anglers 17 and older must have a valid Texas fishing license to fish Ray Roberts Lake, Lake Lewisville, and other public waters in Denton County.
Texas requires anyone age 17 or older to hold a valid fishing license when fishing public waters. This includes Ray Roberts Lake and Lake Lewisville. Licenses are sold by TPWD online, at state park offices, and at many sporting goods retailers.
Certain exemptions apply — for example, some free fishing days each year allow anyone to fish without a license on those specific dates. Licenses and season limits change annually. Check tpwd.texas.gov before you fish to confirm current requirements and any special rules for the lake you plan to visit.
