Frequently Asked Questions
Is the Guadalupe River below Canyon Dam worth fishing for trout?
Yes. TPWD stocks rainbow trout from November through March. The cold tailwater below the dam holds trout in fishable numbers. Use small spinners, PowerBait, or nymphs.
What is the best time to fish Canyon Lake for bass?
Spring (March-May) is best with spawning fish in shallow coves. The rocky canyon walls hold bass year-round and finesse techniques work well in the clear water.
Are Calaveras and Braunig Lakes open to the public?
Yes. Both are city of San Antonio utility lakes open to public fishing with a permit. Warm-water discharge keeps fish active even in winter months.
