Fishing Report (October 10, 2019)


Since 2002, the Castell Guide Service has been offering fly fishing trips for trout and bass in the Texas Hill Country.  With numerous rivers, small lakes and ponds throughout the area, the Texas Hill Country offers year-round fly fishing opportunities. Some of our best fly fishing in Texas is on the Guadalupe River for trout in the winter months and in the spring and fall on the Llano River for bass, sunfish and Rio Grande Cichlids.

Guadalupe River Trout Fishing

The Guadalupe River below Canyon Dam is the southern most trout fishery in the United States.  Guadalupe River trout fishing benefits from the cool waters released from Canyon Dam that sustains a year-round trout population.  In addition to the hold over trout, Guadalupe River also benefits from annual stockings of rainbow trout by Texas Parks and Wildlife Department and the Guadalupe River Chapter of Trout Unlimited.  Fly fishing the Guadalupe River is most successful with nymphs but we do have success with soft hackles, streamers and selected dry fly fishing, especially during our trico hatches in February and March.  Learn More about the Guadalupe.

Llano River Fly Fishing

The Llano River is one of the true fishing destinations of the Texas Hill Country.  In addition to our primary focus on bass (Guadalupe, Largemouth and Spotted), we also target other warm water species such as sunfish, catfish, carp and rio grande cichlids.  There are numerous wade access points on the Llano, but some of the better fishing is accessed by kayak, canoe, or raft.  We also offer mixed trips, where we spend half of the day fishing the Llano and the other half on private ponds.
