Crazy Rainbow Fishing Report


Crazy Rainbow Fishing Report


Grey Reef:

Flows-  1,001 CFS

Fishing Report- 

Fishing is going well throughout the reef . Waters temps are at 57 degrees perfect for active and hungry fish. Moss and algae are also present if you are having problems staying out of it try different rig setups and focus on that. Tricos have been hatching in the mornings and caddis throughout the day if you are looking for dry action. Other bugs that are working include pmd’s, wine worms and other worm patterns. 


Miracle Mile: 

Flows- 1,390 CFS

Fishing Report- 

The Mile is fishing has been fishing well flows are optimal and water temps are at 57 degrees. Worms and caddis have been most productive throughout the area. Look at using hares ear and birds nest size 16-18. There has also been luck on crawdads so give them a try if you are looking to head out. Caddis are by far fishing the best so play around with different patterns until you find something that works!


Fremont Canyon: 

Flows- 82 CFS

Fishing Report- 

We are hearing positive reports in the Canyon. Flows are at operational levels and despite murky off color water fishing is still great! Caddis, RS2’s in the afternoon and brown/black leeches have been most productive on the nymph rig. Copper johns and rock worms are also working well including dry’s so keep an eye out for any hatches. If you are debating on what parts to fish the faster sections of water seem to be fishing the best.


The Big Horn: 

Flows- 1,630 CFS

Fishing Report- 

The Big Horn has been fishing very well lately. Hoppers have been fishing on the edges towards the afternoon and tricos in the mornings. Streamers have also been productive but tough with floating moss throughout the river. Hares ear patterns and bird nest have been doing well much like the mile.
