Lake Austin or Lake Travis: which lake should I buy a waterfront home on?

Choose Lake Austin for a constant water level, proximity to downtown Austin and the highest prices per foot in the region. Choose Lake Travis for open water, bigger views, more lot for the money and a resort lifestyle, accepting that its level rises and falls, sometimes by tens of feet.

The core difference: water level

Lake Austin sits between Mansfield Dam and Tom Miller Dam and is held at a near-constant level, so a dock built today works the same in a drought year. Lake Travis, formed by Mansfield Dam, is the region's main water-supply and flood-control reservoir. Its full conservation pool is 681 feet above sea level, and in drought it can sit tens of feet below that. In dry years some coves on Lake Travis go dry and docks have to be moved out.

Location and lifestyle

  • Lake Austin: a narrow, river-like lake about 20 miles long running through West Austin, from Westlake and Tarrytown out past the Pennybacker Bridge. Many homes are 15 to 25 minutes from downtown. Best for wake surfing and skiing on calm, sheltered water.
  • Lake Travis: about 65 miles of open water through Lakeway, Spicewood, Lago Vista and the Hill Country. Sunsets, sailing, marinas, and golf communities. Most homes are 35 to 50 minutes from downtown.

Price

Lake Austin waterfront is among the most expensive real estate in Texas, with frontage itself driving value. Lake Travis offers more acreage and square footage for the money. For context, the Westlake ZIP 78746, which includes much of the Lake Austin shoreline, had a $1,868,500 median across all sales in the last 12 months, while the Lake Travis ZIPs 78734 and 78669 had medians of $649,250 and $675,000.

What to verify on either lake

  • Dock permits and any planned dock changes: LCRA permits docks on Lake Travis, and the City of Austin regulates Lake Austin shoreline inside city limits.
  • Water depth at the dock in a low-water year (Lake Travis), and bulkhead condition (both).
  • Flood elevation of the home and outbuildings, and the flood insurance quote.
  • Shoreline setbacks and impervious-cover limits before you plan an addition or pool.

Frequently Asked Questions

Does Lake Austin have a constant water level?

Yes, near-constant. Lake Austin is a pass-through lake between Mansfield Dam and Tom Miller Dam, so its level stays steady even in drought, unlike Lake Travis upstream. That stability is a large part of why Lake Austin waterfront commands some of the highest prices per foot in Texas. The lake is occasionally lowered for maintenance or weed control, announced in advance.

Why does the Lake Travis water level change so much?

Lake Travis is a flood-control and water-supply reservoir formed by Mansfield Dam and managed by the LCRA. Its full conservation pool is 681 feet above sea level. In drought, releases for downstream water supply drop the level, sometimes by tens of feet; in floods it can rise well above full pool. Buyers should check how a lot and dock performed in the last low-water period.

Which is closer to downtown Austin, Lake Austin or Lake Travis?

Lake Austin. Much of its shoreline is in West Austin and Westlake, 15 to 25 minutes from downtown. Most Lake Travis homes, in Lakeway, Hurst Creek, Spicewood and Lago Vista, are 35 to 50 minutes from downtown depending on traffic.

Is Lake Austin or Lake Travis better for boating?

They suit different boating. Lake Austin is narrow and sheltered, which makes it a favorite for wake surfing and waterskiing on glassy water, but it is busy on summer weekends. Lake Travis has about 65 miles of wide-open water, coves and marinas, better for cruising, sailing and big-boat days, with conditions that vary with wind and water level.

Who issues dock permits on Lake Travis and Lake Austin?

On Lake Travis, the Lower Colorado River Authority permits docks and shoreline work, and a city may add its own requirements inside its limits. On Lake Austin, the City of Austin regulates docks and shoreline development inside city limits. Before buying, confirm the existing dock is permitted and that any change you plan is allowed.

Do I need flood insurance for a Lake Travis or Lake Austin home?

Check the FEMA flood map and the home's elevation certificate. Lake Travis can rise well above its full pool in a major flood, and low-lying homes and boathouses on either lake can sit in a mapped flood zone, where lenders require flood insurance. Even outside a mapped zone, many waterfront owners carry it. Get a quote before your option period ends.
