Colorado Stream Update: More water, less ice
Current Conditions at Saint Vrain:
The St. Vrain is fishing decent. Nymphing deeper holding water continues to be the best way to find a strike. It feels like spring in the air and the river is starting to respond, but the St. Vrain is still waking up from winter. For best result focus on the warmest part of the day. The lower strectches are ice free for the most part. Make sure you are on the bottom when nymphing.
Spring is here and it’s time to grab the rod and head for the mountains and foothills! March is a great time of year for fly fishing! Take advantage of the sunny days most rivers are ice free and the trout bite is on! Fishing is good but it’s still cold out there! To maximize the bite strive to be on the water from 10 am to 2 pm. The fishing is fair. Clear skies and 40-43 degree weather. The water temperature was between 32-35 degrees and Slightly Off.
