|At these levels, Pedernales Falls is a good park 'n' huck, but the river is too low for a downriver run. Gauge is just upstream of the put-in.|
The Perd doesn't go very often, but when it goes, it goes big. The river bed is extraordinarily wide (often well over 100 yards), but unlike the Upper Perd, this stretch tends to channelize the flow much more, and thus it is runnable at much lower levels. At very high water (10,000+ cfs), the features become Grand Canyon-sized. For more specific beta, see Texas Whitewater.
The crux of the run is at the very end. Pedernales Falls is a series of three features spaced about 200 yards apart. At levels where the downriver run is worth doing, the falls are likely to be deadly, so most boaters choose to take out at river right in the large pool above the top drop and portage the rest of the falls, or to run just the top drop and portage The Slide and S-Turn. The best time to huck the falls is when the river is low and the rest of the run is scrapey. See separate description for the falls for level-specific beta.
Distances and gradient measured using GIS tools in 2015. Average gradient without Pedernales Falls = 14 fpm. Maximum gradient measured from the top of 60/40 Falls to the base of S-Turn (0.34 miles.)

Runnability unknown. You can easily put in below the dam without leaving the LCRA park.
May create a hazard at some levels (beta needed)

See separate description for the falls. Note that, if the river is within the recommended range for the downriver run, Pedernales Falls will be either a Class V or a V+.
