WARNING:  Memorial Day 2015 Flood

In the early morning hours of Sun May 24, 2015, a historic (beyond 500-year) flood on the Blanco River caused the river to crest to 43 feet (8 feet beyond the previous record, set in 1929, and 28 feet above flood stage), destroying numerous homes and businesses and bridges (including Fischer Store Rd.), toppling numerous trees, and killing a handful of people.  The flood was strong enough to scour the river bed down to bedrock, so it is very likely that all rapids along this stretch have changed in character.  Current conditions and difficulty are unknown.  Please submit a comment or a trip report if you have run the river since the flood occurred.

A Class V-VI (level-dependent) narrow limestone chute, approximately 150 yards long.  Texas Whitewater describes it as similar in character to Poudre Falls or Gorilla on The Green Narrows, but with a terminal hole at the bottom.  The Narrows is generally only runnable whenever the rest of the river is scrapey.  Refer to the book for more specific beta.  There is no public access here for park 'n' huck.
