Crazyrainbow Fly Fishing, Casper Wyoming

Fishing Report 06/03/2026

July 9th

Summer fishing has been treating us well.    Things have been fishing great lately, and one of the coolest things we’re seeing is fish looking up. Grey Reef isn’t typically known for its dry fly opportunities, so it’s always exciting when trout start showing interest. While nymphing continues to produce the most results, those keeping… Continue reading Fishing Report 06/03/2026

Fishing around Casper continues to be solid as we move through summer.   Grey Reef is fishing well right now.

Fishing

The North Platte is settling in.  The Grey Reef is currently moving at 500 CFS, and the mix of warm afternoons and surprisingly cool days has created some interesting hatch activity. The cooler weather has also helped keep water temperatures in great shape and water quality clean. On warmer days, we’re seeing solid caddis activity… Continue reading Fishing Report 05/21/2026

Fishing around Casper continues to hold steady despite Wyoming’s unpredictable weather. The Grey Reef is currently running at 500 CFS, and the combination of cool days and occasional warm spells has kept anglers guessing.

Fishing

Spring fishing on the North Platte has been solid, with the Reef continuing to fish especially well. Multiple sections of the river have been productive, and it’s been a fun stretch of spring conditions out there. Flows are currently around 500 CFS, and the river is definitely starting to get “buggy.” We’ve been seeing good… Continue reading FISHING REPORT 05/08/2026

Fishing Report 04/24/2026

Winter time blues? Not around here!  The fishing has been good. That is typical this time of year, consistent good fishing. What has every one really hyped up is where and how the fishing has been good. The answer there is pretty much all sections. Not just the top 10 miles which can be more typical to April on the Reef. The streamer fishing… Continue reading Fishing Report 04/24/2026

Bug

Right now on the North Platte, it’s pretty simple. Don’t overthink it.   A few patterns have really separated themselves lately, and if we had to narrow it down, these are our three favorite bugs in the box right now:   The Little Green Machine has been a staple and continues to produce. It’s a… Continue reading What’s on Our Rigs 04/15/2026

REMINDER: SPAWNING CLOSURES

Spawning

Every spring on the Grey Reef stretch of the North Platte River, it’s game time for spawning rainbows—and that means closures. With the updated regulation this year, the closures will stand from April 1st to May 15th.    The OG “cable to cable” closure below Grey Reef Dam is still in play. It’s not signed,… Continue reading REMINDER: SPAWNING CLOSURES

Report

We are a couple days into the “Flush”, and we are on the home stretch of its completion. It can fish really well IF visibility holds. It is hard to catch fish in chocolate milk and visibility measured in inches. That is just across the board fishing, and the gambling on the Flush.  The powers that be flushed the afterbay and prior to… Continue reading Fishing Report 03/12/2026

Fishing Report Winter

The winter of non-winter weather continues. It has been warm and a great winter to get out on the river. Fishing has been solid on the Reef and the ‘Horn. Highly recommended to take advantage of the weather and get out of the house and get a jump on fishing. Normal wintertime activities (aka skiing) are lacking, but the fishing isn’t. The Reef is till go to… Continue reading Fishing Report 02/17/2026
