Floodwaters shut down several roads across the Texas Hill Country on the morning of Monday, June 15, stranding drivers, damaging roadways and prompting urgent warnings from local officials.

In Bandera County, the sheriff’s office warned residents to stay away from low-water crossings, creeks and other flood-prone areas as water levels climbed quickly. Officials said conditions were expected to become “extremely dangerous” and urged people not to ignore barricades or attempt to drive through flooded roads.

Several roads in Bandera were closed, including Hackberry Street from 11th Street to Main Street; Maple Street from Highway 173 to 15th Street; 14th Street from Highway 16 South to Maple Street; 15th Street from Highway 16 South to Maple Street; and Mulberry Street from Bandera Boulevard to Buck Creek.

Authorities also warned residents to avoid several high-water areas, including Privilege Creek Road, Kyle Ranch Road and State Highway 16 South near Red Bluff.

“DO NOT attempt to drive through flooded roadways,” the sheriff’s office wrote in a social media post. “It only takes a small amount of moving water to sweep away a vehicle.”

The flooding also created dangerous conditions northeast of Boerne. In Sisterdale, volunteer firefighters said crews responded Monday morning to multiple incidents involving vehicles and people stranded at low-water crossings.

Floodwaters caused significant damage to Farm to Market 1376 at Wasp Creek in Sisterdale, forcing crews to close the roadway.

In the Welfare area near Boerne, the Big Joshua Creek crossings were also expected to remain closed throughout the day, according to Waring Fire Rescue.

The City of Boerne also announced several street and intersection closures Monday due to flooding.

Herff Road, River Road and Esser Road were closed after water from Cibolo Creek spilled over the roadway, making the area unsafe for drivers.

Barricades have been placed at the closures, and city officials are asking drivers not to go around them.
