"Trinity" most often refers to two world-class fishing destinations: the Trinity River in Northern California and the Trinity River in Texas. In California, the Trinity River is legendary for its Steelhead and Chinook Salmon runs. The 43-mile stretch from Lewiston to Pigeon Point is a "Wild and Scenic" area perfect for fly fishing, particularly the "fly-only" section just below the Lewiston Dam. Nearby Trinity Lake is also a powerhouse for Smallmouth Bass and Landlocked Chinook. If you are in Texas, the Trinity River is famous for a completely different reason: Giant Alligator Gar. The section of the river between Dallas and Lake Livingston is considered the premier spot in the world to catch "trophy" gar, some of which can exceed 7 or 8 feet in length. For those seeking a more traditional experience in Texas, Lake Trinity (part of the river system) offers excellent White Bass and Crappie fishing. In 2026, both regions require specific state fishing licenses and have strict "catch and release" or seasonal limits to protect the local ecosystems, so always check the current year's "Department of Fish and Wildlife" handbook before casting.
