Blue River Below Green Mountain
UPDATED: 10/07/26
Flow: 135CFS River Graph
Guide Tip of the Week:
Flows have been holding near 140 CFS over the last 7 days, which is on the lower end of the spectrum here, but still very fishable (wading not floating). GMR itself is very low, and due to this we are seeing a bit more moss and silt end up coming out of the dam release into the lower blue, so expect the water to have a bit of a green stain to it. Nymph fishing with small dark patterns like a black RS2, or Black Two Bit Hooker can be effective in these conditions. Small to medium streamers in black or white have also been good on some days. Caddis larva, crane fly larva, and worm patterns could also be effective.
Always keep an eye out for spawning brown trout in the fall, and avoid wading on, or fishing near their redds!

The Lower Blue below Green Mountain Reservoir is a great stretch of public water. It is technically a "tailwater" flowing out of GMR, but it fishes more like a freestone river on some days. There is healthy and diverse population of aquatic bug life, this keeps the Gold Medal trout population well fed. The Lower Blue is fishable both by foot and river craft at certain river flows. We recommend 500 or more cfs to float the ranch section. Skilled oarsman navigate the canyon section as low as 300 cfs.
*The Lower Blue is not legally permitted for any type of commercial guiding, and no shuttle services are offered for this piece of water.*
