Lots of water, very little flooding; Why the Central Texas Water Supply is Recovering

AUSTIN (KXAN): What a difference a few months make. After a widespread drought in the winter and early spring, the late spring and summer rains have kept our grass green and helped fill the water supply.

“Water management in the Colorado River Basin is a cyclical balance between droughts and floods,” said Colorado River Authority Executive Vice President John Hofmann. The lakes have not been so full since the spring of 2019.

“We normally fill up during flood events and then use the water in our water storage tanks as we go through these dry cycles waiting for the next flood cycle to refill everything,” he said. dir Hofmann.

This year’s rains and floods were different

Hofmann added: “We did not see massive historical flooding, we saw good continuous rain, both in the area that feeds the Highland Lakes and in the Austin area, we also saw it in the lower part of the basin. from the Colorado River to the Gulf of Mexico “.

It was almost the perfect way to fill the reservoirs, constantly exceeding the average rainfall, but usually not too much.

“The average is a mathematical number. We don’t experience the average very often. Either we tend to have a lot of them or we tend to be very dry, ”said Hofmann.

Lake Travis and Lake Buchanan are two of the main water supplies in central Texas. Altogether, they gained nearly 250,000 acres of water since late April and peaked on July 22 with the highest water levels of the year.

By the end of August, the water levels were still a few feet above where they normally are, as we headed towards what could be a drier stretch.

Hofmann said, “Our water supplies are in good condition.”

But flooding can occur at any time of the year in central Texas, so we must always be prepared for when we overdo it again.
