Quick Report 08/19/2026

Just popping in with a quick North Platte fishing report. The Casper area took a hit from a heavy rainstorm last week. The runoff pushed a lot of color into the river and muddied things up below Lusby. While the fishing suffered for a bit, we welcomed the moisture with open arms. Wyoming needs every… Continue reading Quick Report 08/19/2026

The Fight for Seminoe Isn’t Over

Save the Miracle Mile

The Seminoe Pumped Storage Project has continued to move through the federal regulatory process, but that doesn’t mean we’re throwing in the towel. If anything, the fight is getting louder. Recent conditions at Seminoe Reservoir are putting the concerns we’ve been raising into real time. The 2013 water year was used in the project’s modeling… Continue reading The Fight for Seminoe Isn’t Over

WGF: New Voluntary Closures (Cody Region)

Due to unseasonably warm conditions, water temperatures are regularly climbing above 70°F and, in some areas, not dropping enough overnight to give trout a chance to recover. The Wyoming Game and Fish Department is asking anglers to adjust accordingly on portions of the Bighorn River in the Cody Region. As a result, Game and Fish… Continue reading WGF: New Voluntary Closures (Cody Region)

Fishing Report 08/05/2026

Happy dog days of summer! Honestly, not much has changed from the bug side of things. The Reef sits at 800 CFS, and the hatches have stayed consistent all summer. Expect tricos first thing in the morning, followed by caddis and yellow sallies. If you find fish keyed in on one of those bugs, don’t overthink… Continue reading Fishing Report 08/05/2026

NEW PRODUCT: Olivia Mae Designs

Every once in a while, something new comes through the door that gets us excited, and that’s exactly what happened when Olivia stopped by the shop with her artwork. She showed us a few of her stickers, and we were hooked right away (pun intended).  Olivia is a 15 year old angler and artist whose… Continue reading NEW PRODUCT: Olivia Mae Designs

WGF: Voluntary Closure (Casper Region)

Water

It is no secret that this has been a strange water year across the West. Between lingering drought conditions, below-average runoff in many areas, and a stretch of hot summer temperatures, anglers are seeing the effects firsthand. As of yesterday, the Wyoming Game and Fish Department instituted a voluntary warm-water catch-and-release closure from noon until… Continue reading WGF: Voluntary Closure (Casper Region)

Quick Report 07/29/2026

Fishing

Just popping in with a quick update on the Grey Reef. Flows have been dropped to 800 CFS. While the river is still fishing well, the lower flows combined with warm temperatures in the forecast mean it’s time to be a little more mindful of conditions on the water. The good news is that all… Continue reading Quick Report 07/29/2026
