Pump House Recreation Area offers campsites with amenities, fishing access, and boat ramps to the general public.  For the wade fisherman Pumphouse holds miles of river both downstream, and upstream of the parking area.  Downstream of the parking area the Colorado River winds through a large meadow, featuring braids, riffles, and undercut banks.  Hiking upstream of the parking area will gradually lead the angler into the mighty Gore Canyon, which contains breathtaking spires, powerful rapids, and some first class trout fishing. 

For the float fisherman Pumphouse is the first viable put in for angling on the Upper Colorado.  Below Pumphouse there are miles upon miles of fishable river to be floated, and numerous boat ramps for loading and unloading.

The Colorado River in this area has very healthy and diverse aquatic insect life.  Prominent hatches include Giant Golden Stoneflies, Salmonflies, Yellow Sallies, Skwala Stoneflies, PMDs, Red Quills, Baetis, Tricos, and midges.  This diverse bug life provides the angler with both nymph, and dry fly fishing opportunities.  Streamer fishing can also be a productive technique here, as the Colorado contains baitfish such as sculpin, whitefish, and juvenile trout.



Current Conditions:


River Flow: 

Flows have been fluctuating between 400 - 550  CFS.   Dont expect a drastic rise in flows here untill we see reservoirs upstream (Dillon, Green Mountain, Wolford, Williams Fork, Windy Gap) fill up closer to their max storage capacities


Water Temperature:


Due to the lack of reservoir release into the Colorado River we are already seeing water temps climb into the upper 60’s.  Trout often die after being handled in water above 65 degrees, please carry a thermometer and STOP FISHING if you encounter these conditions.


Water Clarity:

Water clarity has been between 2' to 4'.  Expect clarity to take a turn for the worse when we see flows rise into the height of this years run off, or after heavy precipitation events.


Current Food Sources:  

Terrestrial insects | stonefly nymphs (Salmonfly, golden, skwala, and Yellow Sally) | Pale Morning Duns | caddis | baetis | midges | small fish, leeches, worms, etc. |

guide tip of the week:


*** plan to get on the river early in the AM, and quit fishing before water temps get to hot ***


  Flows are fluctuating due to surge releases from Williams Fork Reservoir,  and Windy Gap. These surges of cold water are helping to cool the Colorado down, but temps are still hovering in a dangerous zone for trout in the mid 60's.  Before water temps get too warm trout may be found feeding in faster riffles that contain more oxygen, or in deep and cold water later in the day, but you shouldn't be fishing for them by that point anyway.  A dry dropper rig is currently a great way to target faster riffles, while a nymph rig can be used to get into deeper water.
