Lake Austin contains an excellent population of largemouth bass bass with the potential for a trophy. Many bass weighing 8-10 pounds are caught each year. The reservoir also has some good quality bluegill, redbreast, and redear fishing, and has low-density populations of flathead and blue catfish. Fishing during the summer months is best done at night due to heavy recreational boating activity in the daytime. Anglers should use caution when fishing at night.
Lake Austin contains abundant submerged aquatic vegetation (Eurasian watermilfoil and hydrilla). Cover is also provided by the many boat docks that line the shore of the lake. Several major creeks enter the lake including Bee Creek near the Tom Miller Dam and Bull Creek near the 360 bridge crossing.
Largemouth bass anglers should concentrate their efforts in and along the edges of weed beds that line the shoreline. During the summer months (especially on weekends) pleasure boating activity on this reservoir makes fishing from a boat difficult, if not impossible. Anglers should plan trips early in the morning or at night this time of year. Because of the clear water conditions this can be an excellent night fishing lake for bass. Casting white spinnerbaits and topwaters or pitching jigs with heavy bait casting tackle to the weed beds and boat docks often works well. Other popular artificial lures include plastic worms and jerkbaits. For live-bait fishing try minnows suspended under corks along the weedlines. Sight fishing also works well during the spring spawn which occurs February through April, depending on the weather. Because cold water is released from Lake Travis just upstream, bass will spawn later in the year on the upper end of the lake. Look for them in the backs of major creeks, around marinas and in the numerous boat bays that line the lake. Panfishing can also be good along the edge of the weedlines using small tube jigs or crickets on light spinning tackle, or small poppers with a fly rod.
