UPDATE: Area reservoirs and rivers still low as South Texas drought continues

The latest report from Medina Lake shows that it’s only 2.8% full

Area reservoir levels as of 4/11/2024

Tubing season in South Texas is getting underway, but local lakes, reservoirs, and rivers are still notably low as the drought continues. Here’s an update as of Thursday, Apr. 11:

KEY POINTS

  • Lakes and reservoirs like Canyon Lake, Lake Amistad, Medina Lake, and Choke Canyon are well below their respective conservation pools
  • Rivers like the Nueces, Frio, Medina, Guadalupe, and Comal are well below their respective median streamflow
  • Drought continues across much of South Texas

LAKES & RESERVOIRS

Unfortunately, the four main lakes and reservoirs in our area are still notably low, with Medina Lake still in the worst shape at only 2.8% full.

Here’s a breakdown of each body of water, with all information coming from Water Data for Texas.

RIVERS

Local rivers aren’t doing much better. In fact, the Nueces River below Uvalde and the Medina River near Lacoste are currently reporting no streamflow. There’s likely still some water in the rivers at these sites, but it’s just not flowing at the moment.

Here’s a breakdown of the latest river data as of 11 a.m. Thursday, Apr. 11, with all information coming from the United States Geological Survey (USGS).
