River Description

From Stafford/McCutchen; Whitewater of the Southern Rockies:

This is a scenic family and fishing run that is very popular, and is also the put-in for the Gore Canyon run take-out.  This is great, as it allows increased potential for a Gore shuttle and affords ample options at the put-in for the parents and kids to arrive the night before launching.

Pumphouse run can be broken apart in a number of ways. The most popular is to launch from Pumphouse Recreation site and enjoy the upper gorge, which signals its start by the the proximity of a train tunnel on river right.  Mellow sets of class III waves lead to Eye of the Needle, where a rock in the center must be negotiated. Eye of the Needle forms two holes at flows over 4000.  This is the crux of the Upper so you can relax after this as things calm to class II.  Watch for hot springs on river left, as well as the Radium Recreation Site for another river access point.

Red gorge is next, and is much longer and typically jucier than the Upper, creating fairly consistent class III.  A sign marks one of the tougher rapids, Yarmony, which has a wave hole requiring a move from left to center. 

Take out at Rancho Del Rio or Yarmony Bridge on CR1.

Continuing to State Bridge is a short 3.9 mile stretch with some friendly wave trains. 

At low water leave it for the fishermen.
