AUSTIN (KXAN) — The prospect for heavy rain over the next seven days is increasing flooding concerns across Central Texas.
The National Weather Service projects anywhere from 2-10 inches of rain across portions of the KXAN viewing area over the next week. The highest totals are forecast in our eastern counties.
KXAN’s meteorologists said last Friday’s rain led to the second biggest flood ever recorded at Barton Creek and Loop 360. The water level rose from about three feet to 19 feet.
David Johns, Geologist and Program Manager at Austin’s Watershed Protection Department, explained the creek “went from about 100 cubic feet per second of water, which is a nice flow, but not a lot of flow, to over 1,000 cubic feet per second in 20 minutes, which flooded the pool, and then the creek continued to rise up toward somewhere in the neighborhood of 20,000 cubic feet per second.”
\With more rain expected, Johns said all of Austin’s creeks could flood again.
“Right now, with the rain that we’ve had, the soils are saturated. Te water’s going to, the rain’s going to run off rapidly. It’s not going to soak in,” he said.
The Watershed Protection Department said people should also keep a close eye on low water crossings. Know where those are located and avoid them when it rains.
They said some common problem spots include:
- Waters Park, Adelphi Ln, O’Neal Dr. in north Austin
- All of the Spicewood Springs Rd Crossings
- Old Bee Caves Rd near US 290 in Southwest Austin
- Joe Tanner Rd near US 290
- Wasson Rd near South Congress
- Colton-Bluff Springs Rd in Southeast Austin
- Old San Antonio Rd in South Austin
- Cameron Rd near Parmer Lane in far Northeast Austin
Austin Water is also monitoring the conditions. Last year, October’s historic flooding led to the City of Austin issuing a citywide boil water notice.
“The high level of debris, silt and mud requires extended filtration that slows the process of getting treated water into the system,” Austin Water said in a statement last year. “To provide necessary water pressure for fire protection, plants must distribute water at treatment levels not typical of the utility’s high standards for consumption.”
Austin Water’s spokesperson told KXAN Monday at this time, they’re not seeing that kind of water quality, but they’re monitoring the situation.
The Parks and Recreation Department said Barton Springs Pool may remain closed, and even though the Greenbelt reopened Monday, it may still be muddy and slippery. They’re also not ruling out having to close the trail again if we get another round of heavy rain.
