Blue River Below Green Mountain
UPDATED: 04/18/2026
Flow: 95 CFS River Graph
Guide Tip of the Week:
Lower Blue flows have been on the increase the past week but we saw our first drop in water again today from 520 to 470. That number is going to fluctuate sporadically so check the gauge every morning before heading down there. The canyon fishing will be excellent when releases are over 300. Dry fly fishing has been fantastic so make sure to bring more than your nymph box. Blue wing olives are the main ticket right now.

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.*
