One year ago, the city of Austin was placed under a weeklong boil water notice due to water-quality issues in the Colorado River caused by flooding locally and upstream.
Floodwaters from storms upstream reached Lake Travis on Oct. 9, 2018. Additional weeks of local rain and flooding led to a boil-water notice being issued Oct. 22-28 by Austin Water—the city of Austin’s water utility—due to the strain high levels of sediment in the water source was putting on water treatment plants.
According to Austin Water Director Greg Meszaros, what made last fall’s event unique was a combination of the turbidity—or measure of cloudiness in the water caused by sediment and other compounds—in the Colorado River and the length of time it stayed there.
“During most high-turbidity events, [turbidity] spikes and you go through that a couple of days, then business starts to settle down, and customers don’t really know anything happened,” Meszaros told Community Impact Newspaper in October 2019. “Last year it spiked so much higher and stayed high for so much longer a period that we just couldn’t get through it without the need to take public steps and to ask [the public] for help.”
