Lamar, Slough, Soda Butte, and Pebble

September 9, 2020 11:00 am

The Lamar is dropping fast. Flows are 159 cfs now where the river hits the Yellowstone below the Roosevelt Bridge. The same is true for Slough, Pebble and Soda Butte Creek’ volume – flows are low! Water temps are also warming during the day now.

Water quality is good.

Hatches are dwindling – caddis, some PMD’s and Pseudocloeon mayflies, scattered gray drakes.

Hoppers, ants and beetles are definitely working now, too!! A hopper dropper, or large dry stonefly pattern rigged with a black or tan North Fork Special, size 10-14 work well as a dry/dropper rig throughout the NE corner of Yellowstone right now.

Slough Creek campground is closed. Lots of vehicles are parked at the upper Slough Creek Meadows Trail head. Be prepared to see lots of other anglers now that Prime Time is here!!

Pack bear spray and mosquito repellent for security. Both are out in the Lamar Valley and its tributaries.
