After a yearslong drought, South Central Texas has had a few flooding events since June 2025.
While these floods have been devastating for many, we have seen improvements to San Antonio area lakes and reservoirs.
The improvements are substantial enough that you can see the lake level rises from satellites in space! Check it out:

Canyon Lake was at its recent lowest in May 2025, at only 45% full. Now, it is 100% full for the first time since September 2021.
MEDINA LAKE

Medina Reservoir was at a measly 2% full in May 2025, and now it sits at 29% full. That may not seem like much, but it’s up nearly 45 feet!

Similarly, you can see the Nueces River flooding in McMullen and Live Oak counties as the floodwaters gradually make their way to Lake Corpus Christi, which will eventually rise late next week.

Here’s an up-to-date look at area lake and reservoir levels as of late July 2026.
