The Boulder River isn't one of our go to winter fisheries but if you are in the area and we are enjoying some mild weather there are trout to be found. Expect fish to be stacked up in slower water an deeper runs. These conditions are more prevelant on the lower reaches near Big Timber. Smaller nymphs are generally more effective but you don't have to get too technical on fly selection as long as you are targetting the right winter holding water. Try a yarn indicator to help detect subtle takes.
The Month Ahead:
The winter report will remain unchanged for several months.
