Barton Creek at SH 71 (Oak Hill)

What this gauge tells you

The upstream end of the story. Rain in the Dripping Springs headwaters shows up here first, hours before it reaches the swimming holes. If this gauge spikes while Loop 360 is still low, water is on the way — and if it spikes hard, stay out of the creek: flash floods move downstream fast.
