We are getting good reports from Chesterfield Res. where action is picking up for those fish in medium sizes. A few “hogs” are being taken. Use intermediate lines and your favorite leech or damselfly nymph patterns. Daniels Reservoir remains its consistent self with leech, damselfly nymph and midge pupa patterns producing well on the upper end and west side bay. Springfield will improve as weeds disperse, but is producing for those using midge pupa patterns under indicators. Trude and Grizzly springs remain the places to fish on Island Park Reservoir, and blood worm patterns are the ones to use.
