"October is just one of the best times to be on the water," David Callejas of Float On Boat Rentals told KXAN in September, while the City of Austin was still planning to drop Lake Austin about 10 feet from October 12 through November 30. Six days after that story ran, the drawdown was called off.
The City's September 24 announcement named the fall wedding season, University of Texas football and Formula 1 as the events a lowered lake would have disrupted. The same release explained why no new date followed. The calendar has shrunk until fall is the only season a drawdown can happen, and fall is also when the lake earns its keep.
Three seasons were ruled out before the debate started
Lake Austin was last lowered in January and February 2017, and winter used to be the default. The City's Lake Austin page lays out why that option, and two others, are now closed.
| Season | Status for a drawdown | Reason given |
|---|---|---|
| Winter | Not allowed | Since Winter Storm Uri in 2021, LCRA keeps the hydroelectric generators on the Highland Lakes available to the Texas power grid through the cold months |
| Summer | Not allowed | LCRA guidance protects reliable hydroelectric generation in summer too |
| Spring | Not recommended | Fish spawn in shallow water, and spring storms bring safety and erosion risks when the lakebed is exposed |
| Fall | The remaining window | Overlaps peak boating, weddings, UT football and Formula 1 weekend |
This explains the outcome. Stakeholders asked for January and February 2027, and LCRA said no. When the City's stakeholder group met for the fifth time on September 22, the members split roughly in half. Some wanted to push the drawdown to December 1 through January 15, and the rest wanted it canceled. Nobody wanted to keep the October and November dates. With winter closed and fall contested, the City concluded that going ahead would not balance the benefits against the effects on the community.
What October and November are worth on the water
The businesses that spoke up described the fall in dollars. In the same KXAN report, Shawn Smith of Austin Rental Boats estimated about $315,000 in lost revenue and possible layoffs. Callejas put Float On's exposure at more than $100,000, with about 25 captains at risk. Callejas also pointed out that ACL, F1 and UT football bring in visitors who rent boats and shop along the water.
KVUE heard a similar account from John Wolters, captain for Austin Riverboats. He said the company had already canceled six weddings booked during the drawdown window, and that losing October and November would cost "a solid six figures." He drew the seasonal line himself: "January and February, that's one thing." Shoreline residents who spoke to KVUE said much the same. They supported a drawdown in principle and wanted it back in its old January and February slot.
Homeowners and boat operators agreed that winter was the right time. Winter, along with summer, is now reserved for hydroelectric generation, so the only window left was the one Wolters, Smith and Callejas were counting on.
The hydrilla plan now runs on fish
The drawdown was meant to do two jobs. It would expose docks and bulkheads for repair, and it was also presented as a way to set back hydrilla. The City's own page is cautious about that second job. Hydrilla roots survive a drawdown, and the plant can come back quickly. Herbicides are not allowed in Lake Austin because the lake feeds two of Austin's major drinking water treatment plants. Lake-wide mechanical removal isn't considered feasible because hydrilla regrows from small fragments.
That leaves sterile grass carp, which prefer hydrilla to other plants. Stocking has been building since mid-2025.
| Timeframe | Grass carp added |
|---|---|
| July 2025 | 358 |
| November 2025 | 1,995 |
| May 2026 | 2,790 |
| Fall 2026, planned | 7,091 |
The planned fall release is larger than the three earlier ones combined. The City says even after it, the carp population will be only about a third of the 2013 peak, when the fish ate every plant in the lake. Watershed Protection built a predictive model from 25 years of Lake Austin data to set that number. The model shows that anything under about 7,000 fish would not bring hydrilla back down to the City's target of 10 to 30 percent vegetation coverage.
The earlier stockings appear to be working. A City memo dated October 22, reported by KXAN on October 24, says lake-wide hydrilla growth has plateaued in 2026. KXAN noted the contrast with last summer's exponential spread. In the memo, staff say they will ask Texas Parks and Wildlife to allow a higher stocking rate than would normally be permitted. They plan to release carp in the upper, middle and lower reaches of the lake based on where growth is densest, and to publish a Lake Austin Vegetation Management Plan by the end of the calendar year.
A plateau still leaves plenty of hydrilla. TPWD's September 2026 survey counted 575 acres of hydrilla, and Eurasian watermilfoil rose to 99 acres from 76. Coverage is heaviest in the upper lake. Bull Creek was nearly covered, with a cut channel that lets boats through. Hydrilla grew slightly along the shoreline approaching Ski Shores Marina. In Bee Creek Cove near Tom Miller Dam, it reached the surface throughout the cove and covered more area than a year earlier. The stretch from Commons Ford to Emma Long has much less hydrilla, with patches of milfoil along the banks. For an individual dock, the City recommends mechanical removal as the way to get temporary, local relief, and asks that raked hydrilla be disposed of or composted properly.
What a full lake keeps on the calendar
The clearest result of the cancellation is the holiday season on the water. In September, Smith told KXAN that Lake Austin Lights, which operates out of Hula Hut this year, faced cancellation because a lowered lake would have shortened its access. With the lake full, the shoreline calendar through January looks like this:
- Lake Austin Lights, November 20, 2026, through January 3, 2027. Austin Rental Boats runs 45-minute captained cruises from Hula Hut. They pass through two 80-foot floating Tunnels of Lights and past 3D LED displays on the water, with a synchronized show of 20 illuminated boats.
- Mozart's Festival of Lights, November 21, 2026, through January 3, 2027. The 16th annual festival at 3825 Lake Austin Blvd. lists more than 2 million lights, synchronized light shows and live holiday entertainment.
- Laguna Gloria, through January 17, 2027. The Contemporary Austin's The Living Temple: The World of Moki Cherry is the artist's largest U.S. exhibition to date. HOST: Laura Lit has newly commissioned outdoor sculptures on the grounds. The museum is at 3809 West 35th Street. It's open Wednesday and Friday through Sunday from 9 a.m. to 3 p.m., and Thursday from 9 a.m. to 9 p.m.
Three loose ends before you launch
The cancellation didn't reset everything along the shore. Emma Long Metropolitan Park's water utilities were shut off on October 12 for scheduled maintenance and are expected to stay off until January 15, 2027. The park page says showers, sinks, water fountains, hose bibs and the dump station are unavailable until then. Portable toilets are on site for day use and camping, and construction noise is possible from 8 a.m. to 6 p.m. That project is separate from the drawdown and continues as scheduled.
The City's parks closures page still lists the ramp and swimming closures at Emma Long, Commons Ford and Walsh Boat Landing that were tied to the canceled October 12 through November 30 drawdown. Those entries carry an August 20 update date. Call Austin Parks and Recreation to confirm a ramp is open before you tow a boat out.
Shoreline owners who had already lined up drawdown repairs are in a different position. The City has stopped accepting the special permit exemptions it created for the drawdown, though some projects that were already permitted may still go ahead, KVUE reported. The Austin American-Statesman reported that the City will work with individual applicants on next steps, including refunds of permit fees. This is general information, not legal advice. Owners in that position should confirm their options directly with the City and their own advisors.
For the drawdown itself, the City says staff will keep evaluating future opportunities with LCRA and Lake Austin stakeholders.
If you're planning dock work or a waterfront sale around a lake that will stay at full pool for now, Kathryn Scarborough Group follows these Lake Austin decisions closely. We're glad to talk through what they mean for your shoreline.
