River Description

Refer to Texas Whitewater for more specific beta.  Difficulty rating and recommended flow are taken from the book.  Numerous low-water crossings exist along this stretch of river, and some are known to create sieves and/or dangerous hydraulics, so use caution.

The Blanco tends to flash more quickly than most rivers its size, and it can go from moderate to dangerous in less than two hours.  Be sure to note if the river is on the way up or on the way down before beginning a run, and pay attention to the upstream gauges as well.  Even though it can flash quickly, the Blanco will also hold its flow for a relatively long time, so the best times to paddle it are often in the days following a moderate flood.

Distances and gradient measured using GIS tools in 2015.

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.

Rapid Descriptions

Little Arkansas Rd Low-Water Crossing (Class N/A, Mile 2.8)

Texas Whitewater suggests this as an alternate put-in (with parking available along the nearby Flite Acres Road.)  Exercise extreme caution around this crossing (and all other low-water crossings.)

Five-Mile Dam Park (Class N/A, Mile 20.2)

Public park with lots of paved parking.  There is a paved turnaround at river left above the dam that provides riverside parking for shuttle vehicles.

Five-Mile Dam (Class III, Mile 20.3)

At levels where this stretch of river is worth running, Five-Mile Dam can create a dangerous hydraulic, and the downstream hole (the play spot) can become very sticky.  Because of a portruding shelf at river right, avoiding the hole requires some maneuvering.

See separate description of the play spot here.

05/12/12 CFS: ~500 Put In: CR 174 bridge @12:30PM; public parking on Flite Acres is very limited
Takeout: 5 Mile Dam @ 7:15 PM Total Mileage: 17.7 What a rare opportunity it is to float this
river. The Blanco rapids were bigger and more abundant than I expected for such a low water level.
If this gauge is in the green, drop what you are doing and go!

I got the chance to run the blanco river from wimberly to kyle at about 700cfs. It was one of the
best trips I've taken thats around central texas. Water is so blue and green that you think its a
dream. Plus not to forget the land that surrounds the river. Got in at 10:30 from wimberly Cty Rd
1492 and got out at 7:15 at kyle, near the park.
