Lake LBJ

The Lake at a Glance

Lake LBJ occupies a distinctive position in the Highland Lakes chain: it is neither the largest (that's Lake Travis at 19,000 acres) nor the most famous, but it is almost universally regarded as the most livable. The near-constant pool elevation — maintained because LBJ is a pass-through lake with no flood storage capacity — means dock access is reliable year-round in ways that Lake Travis, which can drop 50-plus feet during drought, simply cannot match. That predictability carries a premium in the market, and sophisticated Texas lake buyers know it.

The Alvin Wirtz Dam, completed by LCRA in 1951, created the reservoir on the Colorado River approximately 45 miles northwest of Austin. The Colorado River enters from the northwest and the Llano River joins it at Kingsland, creating a distinctive two-arm lake configuration with different character in each section. The lower lake near Horseshoe Bay is wider, more developed, and anchored by one of Texas's premier destination resorts. The upper lake toward Kingsland is river-fed, slightly stained, and more casual in character.

The county line between Burnet County and Llano County runs roughly down the center of the Colorado River arm of the lake. This is not a geographic curiosity — it is a material financial fact for buyers. Llano County's total effective property tax rate after exemptions runs approximately 0.75%, making it one of the lower-tax jurisdictions in Texas for lake property. Burnet County runs approximately 1.04%. On a $1.5 million lake home — a realistic price point on Lake LBJ — that difference represents roughly $4,500 per year. Over ten years of ownership, the county you land in is worth $45,000 in tax differential.

What Buyers Need to Know First

LCRA manages every dock structure on Lake LBJ through its Shoreline Management Program. A dock permit is required for any structure placed on or over the water, and those permits do not automatically transfer when the property sells. Buyers must confirm that the existing permit is current and compliant, and initiate the transfer process with LCRA before or during the closing period. Unpermitted additions — a roofed boathouse, an extended deck, a boat lift added without amendment — become buyer liability after closing.

The "near-constant level" language that appears in almost every Lake LBJ listing description needs one important qualification: LCRA does lower the lake periodically for maintenance on Wirtz Dam and to allow property owners to address dock maintenance and sediment around structures. These lowerings are scheduled and announced in advance, but they are real. Additionally, during significant flood events, the pass-through design means LBJ can rise rapidly as water from Lake Buchanan upstream is released. The lake is not invulnerable to fluctuation — it just fluctuates for different reasons than a storage reservoir like Travis, and with significantly less magnitude in normal conditions.

Zebra mussels are established in Lake LBJ and the entire Highland Lakes chain. Texas law requires cleaning, draining, and drying all watercraft, trailers, and equipment before leaving any infested water body. Possession and transport of zebra mussels is illegal. This affects every boat owner on the lake — it is not a minor inconvenience, it is a legal requirement with enforcement consequences.
