River Description

Normally a scenic day trip, this section of the Frio also has numerous playspots at higher levels.  At low flows, it is also popular with swimmers and tubers.

Difficulty rating is taken from Texas Whitewater and paddler beta.  Some rapids described below are not yet rated due to lack of information.

Distances and gradient measured using GIS tools in 2015.

Rapid Descriptions

FM 1050 Bridge

Class - N/A Mile - 0
Rapid Thumbnail Missing

Parking is available in the highway right-of-way on the south (downstream) side of the highway on either side of the bridge (the land on this side of the road is part of Garner State Park.)

Low-Head Dam (Garner State Park)

Class - N/A Mile - 2.72
Rapid Thumbnail Missing

Texas Whitewater suggests running far left.

CR 350 (Old Leakey Rd) Low-Water Crossing (Mager's Crossing)

Class - N/A Mile - 3.16
Rapid Thumbnail Missing

Not known to be hazardous

CR 348 (River Rd) Low-Water Crossing (Seven Bluff Crossing/Third Crossing)

Class - N/A Mile - 7.56
Rapid Thumbnail Missing

At "normal" (recreational) flows, river left and center forms a slide, and far river right forms a runnable drop, but at higher flows, the drop turns into a retentive hydraulic.

Low-Head Dam

Class - N/A Mile - 7.98
Rapid Thumbnail Missing

Up to about 1500 cfs, the dam forms a runnable slide with a small hydraulic at the bottom.  At higher levels, it is known to be deadly.  Portage on river left.

Unnamed Rapid

Class - II Mile - 8.14
Rapid Thumbnail Missing

The entire river narrows and takes a jog to the left through some trees.  At high flows, watch for strainers here.

The Chute

Class - II Mile - 8.63
Rapid Thumbnail Missing

Limestone features constrict the river, forming a wave train at about 800 cfs and higher.  The first wave is surfable.

Comanche Crossing

Class - II Mile - 9
Rapid Thumbnail Missing

If the river is running at 1500+ cfs, this low-water crossing creates at 50-yard-wide play hole that gives up spins.  At 2500+, it becomes one of the best play holes in Texas, deep enough for areal moves.

CR 348 (River Rd) Low-Water Crossing (Kenneth Arthur Crossing/Second Crossing)

Class - N/A Mile - 9.54
Rapid Thumbnail Missing

Low-water bridge, generally passable at "normal" (recreational) flows.  If there is insufficient headroom under the bridge, portage at river left.  If water is over the bridge, it can be run at river left, with caution.


Class - II Mile - 10.5
Rapid Thumbnail Missing

Straightforward rapid with a small boulder garden drop in the middle.

The Falls

Class - N/A Mile - 10.8
Rapid Thumbnail Missing

3.5' drop that is runnable river right at all levels.

SH 127 Bridge (Neal's Crossing/Concan Crossing/First Crossing)

Class - N/A Mile - 11.98
Rapid Thumbnail Missing

Bridge is known to be hazardous at high levels, but a new bridge is being constructed that may alleviate that issue.  Take out at river left.


Gage Descriptions

The gauge is 0.75 river miles downstream of the takeout and should thus reflect actual flow for this reach.  Texas Whitewater suggests 500 cfs minimum.  Beta needed regarding best range of flows for whitewater paddling.

County to Vote to Extend Closure on Guadalupe Tonight (TX)

Jason Robertson

The Comal County Commissioner's Court is taking measures that will restrict access to the Guadalupe River indefinitely. AW's primary objective on the Guadalupe is to restore access as soon as possible and to make sure that boater access does not impede on-going rescue and recovery efforts.
