Alvin Dedeaux's Tip of the Week

During the warmer months the trout in the Guadalupe River will be extremely stressed. Low flows and high water temperatures will result in many of the trout dying after being released. Until the cooler temperatures return in the fall it is best to pursue the warm water species.

Description: About Guadalupe River

The Guadalupe River below Canyon Lake dam is listed as one of the top 100 trout streams in America. It is also the southernmost trout stream in the U.S. The Guadalupe River chapter of Trout Unlimited is the largest chapter in the nation. The section of the Guadalupe River we fly fish on is managed as a trophy trout fishery. The bag limit is one trout over 18" per day and must be caught on an artificial lure or fly. The quality of the fishing in this section of the Guadalupe River improves every year. The Guadalupe River is stocked each winter by Texas Parks and Wildlife as well as Trout Unlimited. The average Guadalupe trout will be in the 12" to 14" range. Fish over 20" are not uncommon and we have caught a few trout in the 5lb to 8lb range over the years. The Guadalupe River is a tailwater. Cold water is released from the bottom of the Canyon Lake dam. As a result, the Guadalupe River has the potential for the trout to survive year round. We fly fish on the Guadalupe during the winter months, but trout can be caught every month of the year. The Guadalupe River streambed below Canyon Lake is publicly owned, but the river banks are all private property. Because public access is limited, the best way to fish the Guadalupe River is to float. All of our Guadalupe River floats are done in comfortable, stable rafts with room for 2 fishermen and 1 guide. Full day and half day floats are available. Early morning half day float trips are the best option during the warmer months due to recreational traffic. The Guadalupe River dates fill up fast during the winter months so book your date well in advance.
