WATER FIGHT: As Highland Lake Levels Fall, Residents Fret
Water levels in Lake Travis are more than 20 feet below their average for June. Lake Buchanan is more than 10 feet lower than average. Photo by Todd Wiseman/The Texas TribuneThis is the second in a five-part series called “Water Fight”, a collaboration between KUT News and the Texas Tribune.

As Lake Buchanan drops lower each day amid one of the most intense droughts in Texas history, Donna Williams, owner of Thunderbird Resort on the lake, fears for her business. What was once almost 20 feet of water in the nearby cove is now down to just a few feet, so there’s no convenient place to swim (except for the pool), and the boat ramp is dry. People call and ask if there’s water in the lake before making the trip.
“Basically, what you begin to pray every day and worry about every day is, ‘How are we going to be able to do this?,’” Williams says. “How are we going to be able to keep doing this without water?’”
On the perimeter of Lake Buchanan and Lake Travis in Central Texas, many business owners and residents are wondering the same thing. The lakes are 60 percent full — which translates to containing about 28 percent less water than the long-term average — and they are dropping quickly. The Colorado River that replenishes them has shrunk to a shadow of itself, and farmers and cities continue to demand water from the lakes for their fields and lawns. The results are stark: on Lake Buchanan, for example, boat piers 10-feet tall stand dry, nothing but sandy gravel beneath them.
Lake residents and business owners complain that their needs are treated as secondary to those of farmers and cities.
“As we have been told, we’re two buckets of water — that’s what we’re for,” says Jo Karr Tedder, who represents Lake Buchanan property owners on a 10-year plan currently being crafted to allocate usage of the lakes’ water.
From a long-term perspective, things are even more worrisome for lakeside residents. Lake Buchanan and Lake Travis were constructed in the 1930s, partly for flood control purposes, but largely to serve as reservoirs for the lower Colorado River basin. This distinguishes them from the other four lakes in the Highland Lakes chain, which serve spill-over or hydro-electric purposes and whose levels, according to Tedder, stay far steadier. (The dams on the lakes, particularly Travis, also help prevent flooding, a major problem for 19th-century Austin.)
In theory, then, the primary purpose of the lakes is to serve as “buckets” for water users, like growing cities and especially rice farmers down the Colorado River. But the lakes have taken on an additional role. They have become an economic engine for Central Texas, as people have moved to their shores to enjoy boating and recreation. A study prepared with backing from the Travis County Commissioners Court, due out in late summer, will document the full economic contributions of Lake Travis, but preliminarily it will show some $8.6 billion in property around the lake — and it will also note the tax revenues paid by lake residents.
For a long time, no one thought that there would be enough people to use the water stores in the Highland Lakes reservoirs, says Suzanne Zarling, executive manager of water services with the Lower Colorado River Authority, an arm of the state that manages flows out of the lakes and sells their water.
This changed as the Central Texas population exploded. Still, the lakes’ biggest users by far — accounting for 57 percent of Highland Lakes use last year — is agricultural users a few hundred miles downstream.
Various parties interested in the Highland Lakes water, including rice farmers, Austin Water Utility and environmentalists (who want to ensure there is enough water flowing out of the lakes to preserve animals and plants along the way) have been meeting every few weeks to try to hammer out a 10-year plan for water management on the lakes, which means essentially, how much water each entity can count on and when they will get their water supplies reduced in a drought. That process is nearing its conclusion — another meeting will be held June 28 — but once a plan is formulated it must go through further approvals from the LCRA and Texas environmental regulators.
The lake lobby has been energetically represented by Tedder of Lake Buchannan and Janet Caylor of Lake Travis. To their frustration, they have limited sway over the negotiations. That is because their stakes in the water level are primarily their property values and business interests, and some cities near the lakes don’t even purchase water from the LCRA.
Lake representatives want water levels remain high and healthy. They argue that lake recreation provides an important economic contribution to Central Texas, and lower lake levels means that businesses will suffer, as will the taxes they pay. Karen Huber, the Travis County Commissioner who represents Precinct 3, which includes the Lake Travis area, said that already, property values in some upper reaches of Lake Travis, where the drought has hit hard, are suffering.
The 10-year plan, will ensure “The lakes would be about the same, possibly a little lower in the future,” said James Kowis, the LCRA’s chief water strategist.
But, there is considerable worry among those who depend on the Colorado River Basin that the current drought — or another one in the near future — could prove worse than anyone is planning for. The “drought of record,” still considered the worst in Texas history, occurred from 1947 to 1957, and lake levels dipped to 621,000 acre-feet, an all-time low, in September 1952. Currently, lake levels are nearly twice that, and they are about as low as they were in June 2009, another bad drought year. But little rain is in sight — and if the lakes continue to drop at 35,000 acre-feet per week, which is on the conservative end of LCRA estimates, the amount of water in the lakes could match 1952 levels in four months. Tree-ring records indicate that “megadroughts” as large or larger than that of the 1950s have occurred in earlier centuries, according to an academic paper last year in the Texas Water Journal.
Besides farmers, cities and other environmental-oriented releases, lakes also lose plenty of water to evaporation. Last year, the LCRA says, the two lakes combined lost more water than is absorbed by the city of Austin. This month’s extreme heat and high winds will only accelerate that evaporation. Ironically, the LCRA’s meteorologist has said, the possibility of a busy season of tropical storms and hurricanes, which could bring a surge of rainfall, is a potential bright spot for Central Texas.
Meanwhile, lake levels continue to fall, foot by foot, overnight. As Shawn Devaney, co-owner of the aptly named Vanishing Texas River Cruise Company, heads out across Lake Buchanan in his double-decker tour boat, he points out a narrow strip of the Colorado River, in a vast gulf from tree to tree.
“There’s not much of a river left right now,” Devaney says.
