The cool waters of the Guadalupe River normally make this state park a popular summertime destination.
Years of drought have caused fire restrictions, low river flows and a drop in the number of visitors.
Still, Blake Jarvis brought his grandkids for a dip on a hot August day.
"Just a nice little park, convenient for us, about an hour from San Antonio," Jarvis said.
They've been to the park several times over the years and they usually find a more inviting river.
"What -- three or four feet higher? So it’s down, a hot, dry summer," Jarvis said.
Guadalupe River State Park depends on the river's flow for its water.
Despite a few recent showers, the river has come to a near standstill. No flow means no water for the park's guests.
Water in the park's day use area has been cut off. That means no water to drink or even flush the toilets.
Now those restrictions are in place because the Guadalupe River has dropped so low that almost no water is reaching Canyon Lake. Rangers say the restrictions will be in place until the flow increases.
The Yi family from Laredo knew about the lack of water, but they visited anyways.
"I was kind of disappointed because the water level is so low,” said Phillip Yi. “The view is nice, but the main thing is the river."
But, it’s river in desperate need of rain.
