Lake Travis Water Level FAQ for Party Boat Planners

Lake Travis is a flood-control reservoir

Lake Travis was built in 1942 as a flood-control reservoir for the Highland Lakes chain. The Lower Colorado River Authority (LCRA) manages the level by releasing water downstream through Mansfield Dam.

The full pool is 681 ft above mean sea level. Conservation pool runs from about 660 ft (low) to 681 ft (full). Below 660 ft is drought-stage; above 681 ft is flood-stage.

The level moves 10–40 feet year over year by design. The 2011–2015 drought pulled the lake to 612 ft; the 2018 floods filled it to 704 ft (above flood pool). Both extremes are design behavior, not crisis.

What the level means for the cruise

At 660–681 ft (typical), Premier captains run the same cove anchors, the same swim coves, and the same dam-wall photo route. No change to the trip.

At 645–660 ft (drought-stage), some shallow coves close. The captain anchors at deeper alternates — Starnes Island’s lee side, Hippie Hollow lookout, the central Devil’s Cove zone. The trip is the same; the specific anchor moves 200–500 yards.

Below 645 ft (severe drought), the launch ramp at Anderson Mill Marina becomes the limiting factor. Premier coordinates with the marina on alternative boarding zones. This level happens once a decade.

Above 681 ft (flood-stage), some shoreline rocks submerge and previously-submerged debris floats. Captains run a more conservative route until LCRA finishes the release cycle.

How to check the level yourself

LCRA publishes the live Lake Travis level at hydromet.lcra.org. The dashboard updates every 15 minutes. Bookmark it and check the morning of the charter for context.

The two numbers that matter: current elevation (in ft) and the 7-day trend (rising, stable, or falling). Stable or rising in the 660–681 ft window means a normal day. Falling fast in drought-stage means call the booking team for the cove plan.

Premier’s booking team checks the LCRA dashboard daily. If the level is going to affect a charter, we call the group before they ask.

Common water-level myths

Myth: "The lake is too low to swim." Reality: Premier swim platforms are designed for 6–12 ft of water under the platform, which the cove zones provide at every level above 645 ft.

Myth: "You can’t party-boat at low levels." Reality: 2014 (the deepest year of the 2011–2015 drought) was the second-busiest party-boat season on Lake Travis in the last 20 years. Cove traffic actually concentrated.

Myth: "High lake levels are dangerous." Reality: LCRA releases water downstream during high levels; captains adjust the route. The cruise itself is unaffected outside of brief flood-pool windows.

When the level genuinely changes the plan

Once-a-decade drought stage (below 645 ft): the marina launch zone shifts; some coves close. Premier coordinates the alternate boarding zone in advance.

Active flood-pool release (above 695 ft, brief windows after major rain events): captains run more conservative routes for 24–72 hours. Premier never cancels for level alone; weather is the cancel trigger.

Outside those two cases, the level is a planning factor for context, not a reason to cancel or postpone.

What's next?

Lake Travis level is rarely the trip-defining factor. Pick the month, the boat, and the format — the captain handles the level. To explore Lake Travis history, geography, and the full cove map, see /lake-travis-guide.
