The Boulder is low and the trout are spooky so making longer casts helps to reduce sending trout in the wrong direction. Access can be difficult and travelling up and down the river treacherous with ice shelves and slipper boulders. The good news is that fish are in deeper water where they aren’t as nervous. Standard fair for nymphing like stone fly nymphs and baetis patters is productive. Swinging and stripping streamers can turn some browns from time to time.
The Month Ahead:
Once winter sets in for good the Boulder is a very, very cold river with a lot of ice issues. We largely avoid it until spring.
Long Term Fishing Forecast:
The Boulder will become a good option again in April when the thaw arrives.
