Roaring Fork Hatch Chart

This hatch chart is a generalization of the hatch’s on our local Colorado Rivers in the Roaring Fork Valley, actual hatch’s vary. We do see some major bug hatches on our local rivers. They may be done on one section of river but very active upstream from where they were last week. Most hatches can be followed upstream for weeks and months. Contact either Roaring Fork Anglers or Alpine Angling for current hatch activity on your favorite river spots or check out our Fly Fishing Report.
