The City of New Braunfels closed the Comal River through Tuesday after flow rates jumped to 720 cubic-feet-per-second (cfs), causing poor water clarity and minor amounts of debris along the riverbanks and at the the Tube Chute dam. Heavy rains also increased the flow of the Guadalupe River in New Braunfels to 1,050 cfs, automatically banning kayakers and tubers from the river.
The flow rate for the Guadalupe River at Spring Branch, which feeds into Canyon Lake, rose briefly from around 38.3 cfs to 442. 2 cfs. It is at 38.3 as of 9:20 p.m. For live updates on flow rates along the Guadalupe River visit this page operated by the U.S. Geological Survey.
