Man that's a big question. The two places that come to mind, where you could still entertain your family.
-Kerrville - fishing the Guadalupe above, below, and in town is good (going up river above Hunt, TX is my prefered fishing area), it's not far from Fredericksburg, Luckenbach, Enchanted Rock ect. for the wife and daughter.
-San Marcos/New Braunfels area - you can fish the San Marcos River, Lower Guadalupe and Blanco easily from there. Lots of other stuff for the family to do as well - outlet malls, Gruene, dining, ect.
