Wyoming Bighorn River (Thermopolis Wyoming)
Wedding of the Water downstream
January 28th, 2024
Weather Conditions: Weather Forecast
The weather has been relatively mild for this time of year, with temperatures hovering in the 30s over the past week, causing the snow to melt and creating a spring-like atmosphere. However, it’s worth noting that spring is still a way off. Looking ahead to the coming week, temperatures are expected to remain in the low 40s until Thursday. At that point, a low-pressure system is projected to move in, bringing the potential for new snowfall.
Water Conditions: Current Flows
The water is exceptionally clear and cold, with steady flows holding at around 1000 cubic feet per second (CFS). These conditions are ideal for this time of year. However, it’s important to note that there is some shelf ice at the takeout. Exercise caution when backing your trailer down to the river to ensure a safe and smooth operation.
Hatches and Insects:
Currently, the fish are primarily targeting midges and sow bugs. As temperatures rise in the coming weeks, there’s a possibility of seeing an increase in baetis activity. It’s important to be mindful of the presence of annelids in the Bighorn consistently, so don’t overlook the effectiveness of worms and leeches in the upcoming month. Keep a versatile approach to match the changing insect activity and optimize your chances for successful fishing.
Fish Activity:
The fish are currently congregating in the deep pools at the end of faster runs. It’s worth noting that there are rainbows spawning, likely the Fall Spawn variety. According to information from the Wyoming Game and Fish, there are fish that spawn in the Bighorn throughout the year. While the current redds are easily noticeable, it’s crucial to exercise caution and avoid disturbing these spawning areas. To preserve the world-class fishery, it’s recommended to stay off the redds and allow the fish to spawn undisturbed. This practice helps maintain the health and sustainability of the fish population in the Bighorn River.
Dry Flies: Griffith Gnat, Renegade, Mole Midge
Nymphs: Zebra Midge, Mercury Midge, Poison tongue, two-bit Midge, Epoxy Back Sow, Ray Charles, Juju Midge, Top Secret Midge
Streamers: Thin Mint, Black Woolly Bugger, Rusty Trombone
Catches and Success Rates:
Most of the fish are averaging between 18-20 inches, we are catching mostly rainbows although we have picked up a few more cutthroat and browns in recent weeks.
Local Regulations and Updates: 2024 Fishing Regulations
General Fishing Tips:
Get Deep when fishing the midges using techniques like drop shot and euro nymphing techniques can get the flies in the zone quicker. There is relatively no pressure currently although that is going to change. March and April will see a lot more pressure as we get into the true spring weather.
