If the original plan had held, Lake Austin would be about ten feet low this week, with docks and bulkheads sitting on dry lakebed for repairs. That plan ended on September 24, when the City of Austin canceled the 2026 drawdown. In August we wrote about the River Place side of that drawdown. This is the follow-up, and the news is bigger than one canceled fall. Lake Austin is running out of seasons when it can be lowered at all. For people who live along the upper lake, that means the hydrilla is now a job for fish, measured in years.
The calendar that boxed out the drawdown
The drawdown would have run October 12 through November 30. Its main purpose was giving owners access to docks, bulkheads, boat slips and other shoreline structures for maintenance, along with sediment and debris removal. KUT reported it would have been the first in nearly ten years. KVUE put the last one in January and February 2017.
The gap since then comes from how the calendar has narrowed. Here is each season, as the City's Lake Austin page explains it:
- Winter is out. Winter drawdowns used to be the norm. Since Winter Storm Uri in 2021, LCRA keeps the Highland Lakes' hydroelectric generators available to support the power grid during cold months, so it no longer lowers lakes in winter.
- Summer is out for the same reason. LCRA guidance bars summer lowerings to protect reliable hydropower generation.
- Spring is a poor fit. Fish spawn in shallow water in spring, and spring storms bring safety and erosion risks when the lakebed is exposed.
- Fall is what remains. It's also the lake's busiest stretch of the year. The City cited the fall wedding season, UT football games and Formula 1 as reasons it pulled back.
LCRA offered one more option, December 1 through January 15. Businesses objected to that too, citing holiday activities and seasonal operations. Stakeholders then asked for January and February 2027, and that request was denied. A City memo to Council, quoted by KUT, summed up the result:
"Given these timing considerations, the City determined that proceeding with either of the available 2026 options would not provide the appropriate balance between the operational benefits of a drawdown and its potential impacts on the surrounding community."
Who weighed in, and how evenly they split
The fall timing had real costs for lake businesses. Captain John Wolters of Austin Riverboats told KVUE that the planned dates had already cost the company six wedding bookings and "a solid six figures." Shawn Smith, who owns Austin Rental Boats and Lake Austin Lights, told FOX 7 the cancellation saved more than 150 jobs among lake businesses. He also said he still wants a drawdown in a timely way. Before the cancellation, Lake Austin Marina manager Tara Carr told FOX 7 that the marina sells seven to nine times more fuel in October and November than in January and February. That one ratio explains why fall is the hardest season to give up.
The City's Lake Austin Stakeholder Group didn't reach a clean answer. When it met on September 22, about half the members wanted to move the drawdown to December 1 through January 15 and about half wanted to cancel. Nobody wanted to keep the original October dates. Four days earlier, the group had raised another cost. Some homeowners had already secured permits and signed contracts to work during the drawdown. The City had said it would cancel if there was no consensus, and that's what it did.
The next decision point is late summer 2027
On its lake lowerings page, LCRA says it plans no lowerings in 2026 and will decide in late summer 2027 whether to lower any of the Highland Lakes. Assistant City Manager Mike Rogers said staff will keep evaluating "economic, operational, environmental and community considerations" and stay engaged with LCRA and stakeholders. For anyone who was counting on dry lakebed to work on a dock, that means planning around full water at least until that late-summer 2027 decision.
The drawdown was a maintenance window, not a hydrilla fix. City staff told FOX 7 before the cancellation that the drawdown wasn't a lake-wide hydrilla control. It was too short, and fall lacks the sustained freezes that would hurt the plant. The City's own page adds that hydrilla roots survive lowering and the plant can bounce back quickly. The canceled drawdown mostly cost shoreline owners maintenance access. The work on the weeds was always going to happen elsewhere.
What the upper lake looks like right now
Texas Parks and Wildlife's September survey counted 575 acres of hydrilla, the same as in June, and 99 acres of Eurasian watermilfoil, up from 76. The location matters more than the totals for River Place. Hydrilla is still dominant in the upper parts of the lake, and a modest floodgate release from Mansfield Dam in July didn't significantly reduce it. The middle stretch, from Commons Ford Park to Emma Long Metropolitan Park, has much less hydrilla, with some patches of milfoil along the banks. Hydrilla increased slightly approaching Ski Shores Marina. Bull Creek was almost completely covered, with a cut channel to let boats pass.
Fish do the work now, and slowly
On October 29, Austin Watershed Protection released 7,091 sterile grass carp near Jessica Hollis Park, Walsh Boat Ramp and Bull Creek. That's more than all of the previous recent stockings combined:
| Stocking | Grass carp added |
|---|---|
| July 2025 | 358 |
| November 2025 | 1,995 |
| May 2026 | 2,790 |
| October 2026 | 7,091 |
The City says the stockings since June 2025 appear to have stopped hydrilla from spreading further. Its new predictive model, built on 15 years of Lake Austin data, showed that fewer than about 7,000 additional fish wouldn't bring coverage back down. The goal is 10 to 30 percent vegetation coverage. The model shows a wide range in how long that could take, because weather and other conditions outside the City's control have a big effect. The City doesn't expect visible reductions right after stocking.
The City is cautious for a reason. During the 2010 to 2013 drought, stocking couldn't keep up with hydrilla. When the drought ended, the fish were still in the lake, and starting around 2014 they ate nearly all the lake's vegetation. The lake took about ten years to recover. Even after October's release, the carp population is only about a third of its 2013 peak. The City plans to let the population ease back down as the hydrilla recedes. This is the main lever now, and the City is deliberately pulling it gently.
What's left for a shoreline owner
The other tools are limited. Herbicides aren't allowed in Lake Austin, because the lake supplies two of Austin's major drinking water treatment plants plus private intakes along the shore. Lake-wide mechanical removal isn't practical either. For shoreline owners, the City recommends mechanical removal for temporary, local relief. It notes that a contractor clearing hydrilla around docks should hold a Texas Parks and Wildlife Department permit, and it links to TPWD's nuisance aquatic plant information. The City also suggests cutting back on lawn fertilizer and planting a native buffer along the shoreline, since runoff can feed hydrilla growth.
More rules may be coming. At its October 23 meeting, the stakeholder group discussed a bottom-barrier policy to guide and regulate their use. Members also agreed to add more commercial and Bull Creek area representatives. Owners who are weighing shoreline work can follow updates through the City's Lake Austin email signup. This post is general information, not legal advice. Confirm permits and requirements for your own shoreline with TPWD, the City or a qualified professional before you hire anyone.
The parks this month
The canceled drawdown left some outdated notices online, and one real disruption has nothing to do with it:
- The City's parks closures page still lists boat ramp and swimming closures at Emma Long, Commons Ford and Walsh Boat Landing for October 12 through November 30. Those entries were last updated August 20 and describe the drawdown that was later canceled.
- Emma Long's water utilities are a separate project, and that one is real. Water has been off since October 12 and is expected to stay off until January 15, 2027. Portable toilets are on site for day use and camping. Showers, sinks, water fountains, hose bibs and the dump station are unavailable, and there may be construction noise from 8 a.m. to 6 p.m.
- Emma Long is open 7 a.m. to 10 p.m. and holds 250 cars. Day passes for Fridays through Sundays and holidays are sold online in advance, and walk-ins get in until passes sell out or the lot fills.
