Fishing Report 03/12/2026

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 the beginning of the official flush, which started on Saturday, the river was off color. They are also doing it a little differently this year, during the weekdays it will be raised to 4000cfs during the day, dropped at night. Weekends they will bump at night and drop to 500cfs in the morning So, it is not advised to be on it or wading during that time.  It could get a little rowdy.  Hopefully visibility improves for the weekend, and when the bump happens at night when we aren’t fishing and dropping to fishable levels during the day when we are.  

This raising and lowering can kick up a buffet line of annelids (worms), leeches, crawdads and other macroinvertebrates and the fish feeding heavily.  That is the conditions we are looking for and when it happens, why folks target the Flush. Patterns of choice are worms from San juan, Squirmy size #10 and #12, to rock worms size #14 and #16. Leeches for sure and the variations of the Pine Squirrel are hard to beat.  Junk fishing at its finest. Be careful and mindful this week with the daytime bump. If we get a couple feet of visibility, could be really good. Have fun out there. 

We are moving into the start of some really good fishing. Off Season rates run through the end of the month, get it on it while you can. Peak dates are filling up. This is the time to get with friends and family and plan that North Platte, Wyoming fishing trip. 

Give a call to shop and we are happy to you plan a trip, or local advice if you are headed our way. See you on the water!
