Barton Creek at Loop 360

What this gauge tells you

The gauge everyone quotes. It sits just downstream of the Greenbelt swimming holes, so it is the best single number for "does the Greenbelt have water." 15 - 50 cfs here is ideal: the falls run, the pools stay fresh, and the current is safe. Below 10 cfs only the deep holes hold water; above 120 cfs the current gets swift enough to be dangerous.
