Blue River Below Green Mountain

Fishing Report

UPDATED: 9/14/2023

Flow: 997 CFSRiver Graph

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. Call the shop for the most current conditions.
*The Lower Blue is not legally permitted for any type of commercial guiding, and no shuttle services are offered for this piece of water.*

Guide Tip of the Week:

With Green Mountain full to the brim, flows have increased and we expect sustained releases through September. The canyon has been extremely buggy as of late. Small caddis and PMD’s are on the menu big time. We didn’t see hatches untill mid morning so no need to run down there. Don't discount throwing double dries if you see consistent rising. Look for fish feeding in riffles and on heavy seems. Lastly, keep a close eye on flows and large changes. Fish take time to adjust to bumps and drops in flows. The wade angler needs to be careful, the canyon can be down un-fishable and dangerous.
