Floods are nothing new for the historic Zedler Mill in Luling. It experienced yet another big one just a few weeks ago on Memorial Day weekend. 

“This was the third-worst flood on the river bank here,” Phyllis Hillhouse with the Zedler Mill said.

The San Marcos River overtopped its banks filling the museum and leaving a massive mess.

“We had a lot of debris,” Hillhouse said. “The grass had mud all in it. The driveways were solid mud. We had to bring in new gravel.”

Water got to the steps of this historic home but it stayed out of the reception center. 

The river here is managed by the Guadalupe-Blanco River Authority. With the remnants of Tropical Storm Bill moving across the state, they're finding their watershed in the crosshairs for a second time.

“Some of our most dangerous floods have been caused by tropical depressions,” Bill West, the general manager for the Guadalupe-Blanco River Authority, said.

West says when it comes to flooding, tropical depressions can be worse than hurricanes.

“The tropical depressions from a water standpoint produce much more rain in a broader area,” West said.

But this time, much of that rain is expected to fall to the east, meaning they’re not expecting a repeat of Memorial Day weekend.

While they may not be forced to clean up at the mill from this storm, the potential for flooding remains.

“We never know. With the river we just kind of have to roll with the flow and just try to be prepared,” Hillhouse said.

The Guadalupe-Blanco River Authority says while they may have avoided Bill's worst, any big rain event could cause flooding. For now, it is advising extreme caution on both the Guadalupe and San Marcos rivers.
