Medina Lake, TX

About Medina Lake

Medina Lake is a deep, clear-water reservoir tucked into the Texas Hill Country northwest of San Antonio, straddling Medina and Bandera counties. Built in the early 1900s by damming the Medina River, it is a steep-sided, rocky impoundment with bluffs, submerged timber, flooded creek channels, and long stretches of rugged limestone shoreline. When full it covers several thousand acres, but its level swings dramatically with drought and rain, and those fluctuations are a defining feature of fishing here. Anglers know Medina for its scenic, canyon-like character and for water that often runs noticeably clearer than the muddy reservoirs farther east.

The lake is best known as a largemouth bass fishery, but it carries a genuinely diverse mix of gamefish. White bass run the upper river arm in spring, catfish thrive in the deeper basin, and Hill Country specialties like Guadalupe bass and abundant sunfish add variety. Because the water is clear and structure is plentiful, Medina rewards anglers who fish finesse presentations and pay attention to depth, light, and seasonal positioning rather than just blind-casting the bank.

Fish Species

Medina Lake holds a solid Hill Country mix of warmwater gamefish. The standouts are the black bass and catfish, but several other species make for steady action.

• Largemouth bass — the headline species, relating to rock, brush, points, and standing timber. Clear water means quality fish but spooky, line-shy bass.
• Guadalupe bass — Texas's state fish, a native black bass found in the flowing upper river arm and around current; scrappy and a fun light-tackle target.
• White bass — schooling fish that make a strong spring spawning run up the Medina River arm and chase shad in open water at other times.
• Channel and blue catfish — abundant and reliable, with blues reaching solid sizes in the deeper main basin.
• Sunfish (bluegill and other panfish) — plentiful around rock and brush, great for kids and light-tackle days.

Spotted bass and the occasional white/striped hybrid may also turn up, but largemouth, catfish, and the spring white bass run are what most anglers target.

Best Seasons & Times

Spring is the marquee season. As water warms into the 60s, largemouth move shallow to spawn on protected pockets, flats, and gravel near deeper water, and the white bass push up the upper river arm to spawn — often the most concentrated, fast action of the year. Early morning and late afternoon are prime.

Summer brings heat and bright sun, so fish go deep and gravitate to structure: main-lake points, bluff edges, humps, and standing timber along creek channels. Early morning, late evening, and night fishing are the most comfortable and productive windows, especially for catfish and schooling activity at first light.

Fall is excellent as cooling water triggers shad to migrate and bass and white bass to feed aggressively, frequently busting bait on the surface. Reaction baits shine, and overcast days extend the bite well past dawn.

Winter slows things down but can produce big, lethargic largemouth on slow finesse presentations fished deep around bluffs and channel structure. Midday, when the sun has warmed the water a few degrees, is often the best window in the cold months.

Techniques & Baits

Medina's clear water and rocky structure favor finesse and natural presentations for bass, while catfish reward bait fished near the bottom.

• Largemouth: Drop shots, shaky heads, Texas-rigged soft plastics, and Carolina rigs around rock, points, and timber excel in clear water. Use natural shad and craw colors and lighter fluorocarbon line to fool line-shy fish. Crankbaits and spinnerbaits work when fish are active or water is stained after rain; topwater shines at dawn, dusk, and during fall schooling.
• Guadalupe bass: Light spinning gear with small soft plastics, in-line spinners, and tiny crankbaits fished in or near current in the upper river arm.
• White bass: During the spring run, small jigs, spoons, inline spinners, and live minnows in the upper river; in open water chase the schools with slabs, jigging spoons, and shad-imitating swimbaits.
• Catfish: Cut shad, live bait, prepared stinkbaits, and nightcrawlers fished on the bottom along channel edges, deep flats, and near structure; blues respond well to fresh cut bait.
• Panfish: Small jigs, worms, and crickets under a float around rock and brush.

Because the lake is clear, downsizing line and lures and fishing low-light periods consistently improves bass catch rates.

Access & Launches

Medina Lake sits in the Hill Country between San Antonio and Bandera, and there are public boat-launch options as well as private and community ramps, marinas, and lakeside concessions around the shoreline. Bank and shoreline access is more limited than on some flatland reservoirs because much of the perimeter is private and the terrain is steep and rocky, so a boat or kayak greatly expands your options. One important planning note: Medina's water level fluctuates significantly with drought and rainfall, and during low-water periods some ramps can become unusable or leave boats with limited access. Before a trip, confirm the current lake level and which ramps are open and floating. Always observe posted private-property boundaries and use designated public access points.

Regulations & Licenses

A valid Texas fishing license with the appropriate freshwater endorsement is required for anglers of licensing age; check current requirements and any exemptions before you fish. Largemouth bass, white bass, catfish, and other species are managed under statewide rules that may include minimum or slot length limits and daily bag limits, and these can change or differ for specific waters. Always review the current Texas Parks and Wildlife Department (TPWD) freshwater fishing regulations for size and bag limits, any special provisions that apply to Medina Lake, and rules on bait, culling, and catch-and-release before heading out. When in doubt, practice selective harvest and release of larger bass to help sustain the fishery.

Frequently Asked Questions

What fish is Medina Lake known for?
Medina Lake is best known for largemouth bass in its clear, rocky water, along with strong channel and blue catfish populations and a popular spring white bass run up the Medina River arm. Native Guadalupe bass and plenty of sunfish round out the fishery.

When is the best time to fish Medina Lake?
Spring is the prime time, with largemouth moving shallow to spawn and white bass running up the river arm. Fall is also excellent for schooling bass and white bass chasing shad. Summer fishing is best early, late, or at night, and winter produces slower but sometimes larger bass on finesse baits.

Does Medina Lake have largemouth bass, and how do you catch them?
Yes, largemouth bass are the headline species. Because the water is clear, finesse presentations like drop shots, shaky heads, and Texas-rigged plastics in natural shad and craw colors on lighter fluorocarbon work well around rock, points, and timber. Crankbaits, spinnerbaits, and topwater produce when fish are active or water is stained after rain.

Do I need a license to fish Medina Lake?
Yes. A valid Texas fishing license with the appropriate freshwater endorsement is required for anglers of licensing age. Size and bag limits apply and can vary, so check the current Texas Parks and Wildlife Department regulations before your trip. Also confirm the lake level and open ramps, since Medina's water level fluctuates significantly.
