crazyrainbow fly fishing, Casper Wyoming


Chocolate RS2
RS2 in chocolate is a great nymph

Current CFS.

  • The Reef is at 2,200 CFS.
  • The Miracle Mile is at 1,000 CFS
  • Fremont Canyon is at 75 CFS

Fremont Canyon and the Reef are both down, and both are fishing well. Hopper fishing continues to improve and we are starting to see some dry fly action on certain parts of the river with tricos spinning in the morning and hopper in the afternoons.


Nymphing has been the most consistent method to catch fish, and don’t forget that your indicator can be replaced with a hopper!

Fly fishing quote of the week:

“The essentials of a good fly-hook: the temper of an angel and penetration of a prophet; fine enough to be invisible and strong enough to kill a bull in a ten acre field. “
