Following a rainy Memorial Day weekend and recent storms in the Texas Hill Country, Medina Lake saw a slight rise in water levels early this week, shifting by only a slim margin from where the reservoir sat just days ago.
According to Water Data for Texas, the lake rose from 977.06 feet — 3.9% of its capacity — on Tuesday, May 26, to 977.12 feet — 4% of its capacity — on Wednesday, May 27, as rain waters poured over the area overnight. In that same time span, the body of water rose 44-acre-feet across its surface area, a marginal bump in a lake that remains still 96% below its full capacity.
Despite the brief uptick, data show that Medina Lake remains lower than earlier this year. The reservoir was at its highest in January 2026, when it reached 979.59 feet in elevation, or 4.7% full, on New Year’s Day. Since then, local water authorities say it’s been on a gradual decline, despite sporadic upticks.
The lake has hovered near the 4% mark in recent days, with minor fluctuations driven by periods of rainfall, but it’s one of the few times the lake has reached that level since the beginning of the year.
“Since the beginning of the year, the lake has been on a slow and steady decline,” said Dave Mauk, the Bandera County River Authority and Groundwater District general manager.
The river authority said April and May marked the lake’s first slight increase since the beginning of the year.
“[The] lake is almost completely gone,” Mauk said to MySA, via text message. “This drought is punishing and chronic. The recent increase is not meaningful.”
