Lake Austin was scheduled to start dropping on Monday, October 12. The City of Austin announced on August 20 that the Lower Colorado River Authority would lower the lake by about 10 feet, to a range of 481.8 to 482.8 feet above mean sea level, and hold it there through November 30. On September 24, the City canceled the 2026 drawdown.
So the water will stay at its normal level this fall, and docks, boathouses and bulkheads will stay underwater. The more lasting news is why the plan fell apart. Lake Austin used to have a quiet season when lowering the water bothered very few people. That season is gone. Winter is now off-limits for reasons tied to the state's electric grid, and fall is when the lake does its busiest business. A drawdown now has to fit into a calendar with almost no open space.
What the Lowering Was For
Lakefront owners care about drawdowns because of what becomes reachable when the water drops. The City's August 20 memo to Council gives the main purpose as letting property owners maintain shoreline structures such as boat docks and bulkheads, along with dredging and debris removal. Austin Fire and Austin Parks & Recreation also had maintenance work that would have been easier with the water down. City staff planned to reassess native Unionid mussels that were documented during the last drawdown, and they were looking at partnering with community groups on a lake cleanup.
The public side of the lake would have changed as well. Under the announced plan, public boat ramps would have closed and swimming at Emma Long Metropolitan Park would have been prohibited.
The memo also shows how rare these windows have become. Drawdowns usually lowered the lake about 10 to 12 feet, and the full cycle from first release to refill takes about seven weeks. From 2001 to 2011 there were eight of them. Since 2011 there has been one, in January and February 2017. KUT noted that this fall's drawdown would have been the first in nearly 10 years.
Under the earlier pace, a dock owner could usually expect another low-water window within a year or two. Under the current pace, a structure built after 2017 may never have been fully exposed for inspection.
Why Winter Is No Longer an Option
Every past drawdown happened in winter. That made sense for a long time, because winter was when boat rentals, waterfront dining and lake weddings were slowest.
That changed after Winter Storm Uri. LCRA operates Tom Miller Dam, which forms Lake Austin, and generates hydroelectric power from releases through it. Since the 2021 storm, LCRA has stopped scheduling lake drawdowns in winter so that hydroelectric generators along the Highland Lakes stay available to the Texas grid during cold months.
This is the main reason for everything else in this story. Pushing the drawdown back a few months used to be the easy compromise, and that option no longer exists. The months with the least conflict are now the months the grid needs.
Fall Was Tried, and Then a Later Window
Once winter was ruled out, the City and LCRA scheduled fall. The response from the lake's businesses came quickly, and it explained what fall is worth to them.
On September 18, KXAN reported that Austin Rental Boats estimated the drawdown could cost its companies about $315,000 and several jobs. The company also warned that its Lake Austin Lights tour, which operates from Hula Hut, might be canceled because boats couldn't reach the water during the holiday-light season. In the same report, Float On Boat Rentals described October as a prime month because of visitors in town for ACL, Formula 1 and UT football. The company estimated more than $100,000 in lost revenue and about 25 captains without work. Both operators objected to having only seven weeks' notice. Float On also questioned whether there would be enough contractors to finish the requested work in the time available.
KVUE reported that Austin Riverboats had already canceled six weddings and considered the Formula 1 weekend a key business period. Float On raised another concern: muddy water during the refill could keep business slow toward the end of the year. In separate KVUE coverage, Ski Shores Cafe described September and October as strong months and said it wanted much more advance notice. One resident quoted in the same report supported a drawdown but wanted it in January or February, when past drawdowns took place.
Council Member Paige Ellis told KXAN that the City wanted to avoid hitting some people disproportionately, and that timing, depth and LCRA's constraints had been under discussion for a long time.
KUT's account of the September 24 memo shows the calendar running out. LCRA offered December 1 through January 15 as an alternate window, and businesses raised concerns about holiday activities and seasonal operations. Stakeholders then proposed January and February 2027, which was denied under the post-Uri winter policy.
| Window considered | What it conflicted with | Outcome |
|---|---|---|
| Oct. 12 – Nov. 30, 2026 | Fall weddings, UT football, Formula 1 | Canceled |
| Dec. 1, 2026 – Jan. 15, 2027 | Holiday activities, seasonal business | Not pursued |
| Jan. – Feb. 2027 | LCRA's winter grid policy | Denied |
The City's memo said 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."
Each objection made sense on its own. Together, they cover nearly the whole year.
The Hydrilla Question
Some residents may have hoped a drawdown would also clear out invasive weeds. The City's own figures don't support much hope there. According to the City's Lake Austin page, a June 2026 Texas Parks and Wildlife Department survey found 575 acres of hydrilla and 75 acres of Eurasian watermilfoil. Hydrilla was down from 592 acres in February, but the total area of invasive plants stayed about the same.
The City says hydrilla roots survive drawdowns, the plant can grow back quickly, and removing it mechanically across the whole lake isn't feasible. That's why the August memo described a drawdown as offering only possible temporary management of nuisance vegetation. The City's main approach is stocking sterile grass carp. Its page describes plans for 2,790 more fish to bring stocking density to eight per acre of hydrilla, and it cautions against expecting an immediate drop in hydrilla. The cancellation took away a short-term tool. The long-term weed management plan was never built around drawdowns.
Where This Leaves Dock and Shoreline Work
The City built a special site-plan exemption form for this drawdown, and it is no longer accepting it. Staff will contact people who already applied about next steps. Outside that process, the City's standard guidance still applies. Construction on, under or next to Lake Austin may need specific reviews and permits, and an approved site plan or exemption is required before a building permit application.
This year's dispute also raised a capacity issue. Float On's concern that seven weeks might not be enough for contractors to finish the work points to what would happen in any future window. A rare drawdown means years of deferred shoreline work all competing for the same short stretch of low water.
What Comes Next
LCRA states that it does not plan to lower any of the pass-through lakes in 2026, and that it will decide on 2027 lowerings in late summer 2027 based on conditions at that time. LCRA lowers Lake Austin at the City's request, and the City has jurisdiction over dock regulations and vegetation management on the lake. Any future drawdown starts with the City.
Assistant City Manager Mike Rogers said staff "will continue evaluating economic, operational, environmental and community considerations associated with potential future drawdowns." KUT reported that no date for a future drawdown has been announced.
For now, Hula Hut, Ski Shores Cafe and the boat operators at Lake Austin's marinas will have full water through the rest of the fall, and Emma Long will keep normal swimming access. The last time the lake was lowered was January and February 2017, and the earliest decision on another lowering is scheduled for late summer 2027.
