If you want to chase trout then head to the Guadalupe River below Canyon Lake dam. This is the southern most river in the U.S. to trout fish. Recommend you join Guadalupe Trout Unlimited, GRTU Home
and also join the Lease Access Program. As you should know most all property on the river is private. The club obtains fishing access rights in many areas. There are also places you can launch and float the river if you desire. It's a blast getting to help with the club trout stocking 3-4 times each winter. The state also stocks many times during the winter but with much smaller fish than GRTU stocks.
