Current Conditions:
The Boulder River is running slightly above average for this time of year, but still cold. With the Boulder's crystal clear water in the spring, it means the trout are spooky so making longer casts and a stealthy approach helps to reduce spooking trout. But because fish are in deeper water right now they aren’t as nervous. Water temps in the Boulder River typically remain cold so the best fishing has been in the afternoons. Hatches of Blue Winged Olives can occur any day but will increase in frequency as water temps consistently run in it the 40s.
The Month Ahead:
The Boulder River has snowmelt runoff a bit later than the Yellowstone because of the high elevation snowpack and the fishing should be good until then. Both nymphing and dries over the baetis hatch will be productive.
