LOW IN THE INFLOW Inows into Lake Travis have lowered substantially in recent years, even though average rainfall has remained similar to past trends. One acre-foot equals 325,851 gallons of water, and here is a look at recent inow into the lake in acre-feet. 80,385 51,890 12,370 Since 1942 February average 2008-15 February average February 2022
TURNING UP THE HEAT
Drought occurs when there is less-than-average rainfall for an area over a certain period of time. Megadrought occurs when a drought lasts longer than two decades. Projections show Texas could experience a megadrought in its future, with higher average temperatures and more 100-degree days compared with current levels.
48.8 days over 100 degrees Fahrenheit by mid-21st century*
+34days ≥ 100 degrees Fahrenheit by mid-21st century*
103.6degrees Fahrenheit average mid-century summer temperature*
+3.9 degrees Fahrenheit higher annual average 7-day temperature

governments, $3.6 million in hotel and mixed bev- erage taxes and $45.2 million in sales tax from com- mercial businesses annually, according to the Lake Travis Coalition. When Lake Travis is low, people nd other places to go, Clark said. Boat sales were down almost half from 2010-14, with at least $30 million in lost revenue. There were also losses in waterfront property values, hotel tax revenue and mixed-beverage tax revenue, accord- ing to the Lake Travis Coalition. Owning a business during a drought is a lot like navigating a pandemic, Clark said. Businesses must operate at limited capacity, but rather than gradu- ally allowing more people inside as the infection rate goes down, the capacity of lakeside businesses shrinks as the drought drags on. To protect his livelihood, Clark said he has worked to diversify his revenue streams by open- ing businesses not reliant on water levels. In times of drought, the businesses operating at full capacity can oset those impacted by low lake levels, he said. He has also tried to make his businesses more resil- ient by growing his on-land customer base. “It’s going to hurt, and it’s going to leave a mark, but it’s not necessarily going to be devastating,” Clark said. “We just kind of go through life hoping In 2011, nearly 50% of available water in Lake Tra- vis was released downstream to irrigators for farm- ing, according to the CTWC. After 2011, the LCRA put a system in place to prevent water being sent downstream to irrigators when needed for use by cities. The problem with this system is that Austin is good at conserving water, which makes it appear that there is more water available than there really is, Tedder said. The combined storage of Lakes Travis and to dodge bullets.” Mitigating drought
Buchanan is about 2 million acre-feet when full. One acre-foot is equal to 325,851 gallons of water. As of March, the LCRA reported the combined storage of both reservoirs was at 77% capacity. To prevent the overestimation of upstream water resources, the CTWC recommends the LCRA imple- ment a “safe yield” system that would keep enough water needed to sustain cities in the upper basin for at least a year. The LCRA declined to comment for this story but released a statement that the plan in place is designed to maintain enough supplies for municipal water use even during the worst drought the region has seen. In addition to improved conservation eorts, it is also important to increase wildre preparedness, said Will Boettner, Travis County wildre mitigation ocer. For western Travis County, the abundant greenery presents ample opportunity for a wildre during a drought. Western Travis County has few re hydrants, so most re trucks use water from attached tanks, Boettner said. During a drought when water levels in Lake Travis are lower, water pressures may be too low or water may become unavailable. “That’s why we’ve become much more proac- tive with trying to prevent res from ever getting started,” he said. While the future of Lake Travis in the face of drought remains uncertain, it is key to keep looking ahead, Tedder said. “It’s hard to get the word out and educate people about what’s really happening,” Tedder said. “You need to be doing your hard planning when there is plenty of water, because when you’re in a drought, it’s too late.”
