Lake Austin Drawdown 2026: What Boaters Need to Know

If you’re planning to get out on the water in Austin this fall, there’s an important change coming to Lake Austin. The City of Austin and the Lower Colorado River Authority (LCRA) have officially announced a planned Lake Austin drawdown from October 12 through November 30, 2026.

The lake will be lowered approximately 10 feet, giving property owners and City departments access to docks, bulkheads, boat slips and other shoreline areas that are normally underwater.

For anyone considering Lake Austin boat rentals, wondering what this means for boating season, or simply curious about why Austin occasionally lowers the lake, here’s everything you need to know.

When Will Lake Austin Be Lowered?

The Lake Austin drawdown is scheduled to begin October 12, 2026.

Rather than dropping the lake all at once, LCRA plans to lower Lake Austin gradually at a rate of no more than approximately one foot per day. Depending on conditions, it could take around three weeks for the lake to reach its target lowered elevation of approximately 481.8 to 482.8 feet above mean sea level.

The refill is scheduled to begin November 24, using water released from Lake Travis. The lake can rise by as much as approximately two feet per day during the refill process. It is expected to return to its normal operating range by November 30.

That means the overall drawdown period will last roughly seven weeks, although the lake will not be at its lowest level for that entire period.

Why Is Lake Austin Being Drained?

First, Lake Austin isn’t technically being completely “drained.” It’s a controlled drawdown, meaning the water level is intentionally lowered for a temporary period.

The primary purpose of the 2026 drawdown is to make shoreline maintenance easier.

With the water approximately 10 feet lower than normal, lakefront property owners can have better access to areas that are usually underwater. This can provide an opportunity to:

Repair docks and boat slips
Repair or reconstruct bulkheads
Dredge boat slips
Remove accumulated debris
Perform shoreline maintenance
Address nuisance aquatic vegetation

Austin Fire and Austin Parks & Recreation also plan to use the drawdown to complete maintenance projects.

Some private shoreline work will require permits from the City of Austin or Texas Parks and Wildlife Department. Property owners should confirm requirements before beginning work.

What About the Hydrilla in Lake Austin?

Hydrilla is another major issue surrounding Lake Austin right now.

Hydrilla is a fast-growing invasive aquatic plant that was first observed in Lake Austin in 1999. In June 2026, Texas Parks and Wildlife identified approximately 575 acres of hydrilla in the lake, with particularly dense growth in the upper five miles below Mansfield Dam.

While lowering the lake exposes vegetation and gives property owners an opportunity to remove nuisance plants around their shoreline. The City does not consider a drawdown a long-term solution for hydrilla.

Hydrilla can survive through underground tubers that remain in the sediment. In fact, previous experience has shown that hydrilla can return after the lake refills. The City is currently using sterile grass carp as its primary long-term strategy for managing hydrilla.

So while vegetation management is part of the conversation surrounding the drawdown, shoreline and infrastructure maintenance are major reasons for lowering the lake.

Has Lake Austin Been Drained Before?

Yes. Controlled drawdowns are nothing new for Lake Austin.

Historically, the lake has been lowered periodically to give homeowners access to shoreline structures and to help manage aquatic vegetation. Records show multiple drawdowns dating back decades, including drawdowns in 1999, 2001, 2002, 2003, 2004, 2005, 2008 and 2011.

During some earlier drawdowns, Lake Austin was lowered approximately 12 feet for around six weeks. Property owners used the exposed shoreline to remove vegetation and perform other maintenance.

Historically, many of these drawdowns happened during winter.

That changed following Winter Storm Uri in 2021.

LCRA no longer schedules planned Highland Lakes drawdowns during the winter because hydroelectric generators at the dams. They may be needed to help support the Texas power grid during periods of extreme cold. Summer drawdowns are also avoided because of power-generation needs.

Spring presents its own challenges because lowering the lake could affect fish spawning, while spring storms can create additional erosion and safety concerns.

As a result, October and November have become the preferred window for planned drawdowns.

What Should Boaters Expect During the Lake Austin Drawdown?

This is where the 2026 drawdown becomes especially important for anyone planning a fall lake day.

Public boat ramps on Lake Austin will be closed throughout the drawdown. Swimming will also be prohibited at Emma Long Metropolitan Park during this period.

Water levels and navigable areas will look very different from what regular Lake Austin boaters are accustomed to seeing. Areas that are normally underwater may become exposed. D

ocks and boat lifts designed for normal lake elevations may no longer be usable.

Water levels may also fluctuate. LCRA can release water from Mansfield Dam when necessary to maintain lake levels or meet downstream water demands. Conditions near the upper end of Lake Austin may therefore differ from the target elevation measured near Tom Miller Dam.

If you normally keep a boat on Lake Austin, talk with your marina, dock operator or service provider ahead of the drawdown about how the lower water level may affect your boat and lift.

If you’re relatively new to renting or boating on Austin’s lakes, our What to Know Before You Go guide is another helpful resource for preparing for a day on the water.

How Lake Austin Property Owners Can Prepare

If you own property along Lake Austin, now is the time to plan rather than waiting until the water starts dropping.

Start by inspecting your dock, boat lift, bulkhead and shoreline for maintenance that may be easier to complete when the water is lower.

If you’re considering dock repairs, dredging or bulkhead work, determine whether permits are required and schedule qualified contractors early. The City of Austin requires permits for a variety of construction and maintenance activities involving docks, bulkheads and the lakebed.

Property owners and contractors should also remember that the drawdown schedule isn’t guaranteed. Flooding, power shortages or other unexpected conditions could cause the drawdown to be shortened or canceled.

LCRA advises people working near the exposed lakebed not to leave equipment unattended and to remove tools from the shoreline when they are not being used.

Lake Austin Drawdown Preparation Checklist

Before October 12, Lake Austin property owners may want to:

Inspect docks and boat lifts
Check bulkheads and shoreline structures
Schedule any necessary repairs
Confirm City or state permit requirements
Make arrangements for boats that could be affected by lower water levels
Remove or secure equipment near the shoreline
Talk with dock, marina or boat service providers
Continue monitoring LCRA and City of Austin updates

Planning ahead will make it much easier to take advantage of the maintenance window once water levels begin to drop.

Planning a Boat Rental in Austin During the Drawdown?

The good news is that Lake Austin isn’t your only option for getting on the water.

While the Lake Austin drawdown will affect access and normal boating conditions, Lake Travis boat rentals provide another way to enjoy an Austin lake day during the fall.

If you haven’t spent much time on Lake Travis, start with our guide to the 5 Best Things to Do on Lake Travis for ideas on how to spend your day.

Lake Travis and Lake Austin serve very different purposes within the Highland Lakes system. Lake Travis is a major water-storage reservoir, while Lake Austin is a pass-through lake between Mansfield Dam and Tom Miller Dam.

Water from Lake Travis will actually be used to refill Lake Austin beginning November 24.

For visitors searching for boat rentals Austin during the drawdown period, checking Lake Travis availability may be the easiest option.

Float On offers both Lake Austin boat rentals and Lake Travis boat rentals, and our team can help you determine which lake makes the most sense based on current conditions, access and your group.

What Does the Lake Austin Drawdown Mean for Lake Travis?

Lake Travis is not part of the Lake Austin drawdown.

In fact, Lake Travis plays an important role in the process because water released through Mansfield Dam will eventually help return Lake Austin to its normal operating level.

If you’re wondering what Lake Travis looks like before heading out, bookmark our Lake Travis Water Level: Weekly Report. We use it to share updates about water levels and boating conditions.

Lake Travis also offers a very different boating experience from Lake Austin. If you’re considering moving your lake day to Travis during the drawdown, our guide to Do You Need a Captain to Rent a Boat on Lake Travis? explains what to expect from a self-captain rental.

For boaters who normally use Lake Austin, Lake Travis may be a great alternative during the drawdown. If you keep your own boat, check with your Lake Travis marina about launch and storage options, or research boat storage Lake Travis if you need a temporary place for your boat.

If you’d rather skip the logistics altogether, renting a boat is another option.
