Lake Buchanan, TX Fishing Report & Live Conditions
Lake Buchanan, TX fishing report
Lake Buchanan is the headwaters reservoir of the Highland Lakes chain on the Colorado River, and its character shifts dramatically with the seasons. Striped bass are the star attraction, drawing serious anglers throughout the year, but spring and fall are peak periods when threadfin and gizzard shad schooling activity pulls big fish toward the surface. Largemouth bass fishing picks up as water temperatures climb into the low 60s in late winter and early spring, with fish staging on rocky points and submerged creek channels before the spawn. Flathead and blue catfish thrive here year-round, benefiting from the deep water and strong river-channel structure that Buchanan's upper end provides.
For stripers, watch for birds working baitfish on the surface early morning and run topwater walk-the-dog plugs or swimbaits through the commotion fast. When fish go deep in summer heat, downrigging or live-lining shad over main-lake structure in 20 to 40 feet produces. Largemouth respond well to soft plastic crawfish and creature baits worked slowly around chunk-rock banks and flooded timber near coves. The upper river arm near the Colorado River inflow concentrates all three species during periods of active current flow following rainfall, as bait stacks up and predators follow. Catfish anglers do well anchoring the deep river channel with cut shad on bottom.
