River Description
The Upper Perd doesn't go very often, but when it goes, it goes big. The river bed is extraordinarily wide (often well over 100 yards), so even thousands of cfs on this run will still be surprisingly shallow. Many whitewater boaters won't bother with this stretch until it gets near 10,000 cfs. For more specific beta, see Texas Whitewater. Difficulty rating and range of recommended flow are taken from the book.
