Crane Prairie is a highly channelized reservoir with huge amounts of chironomids that help these rainbows reach their famed proportions. Strong hatches of damselflies during the summer supplement the chironomids.
Callibaetis are the only dry flies you will likely find this time of year. Bring a selection of cripples, duns, and spinners. Balanced leeches under an indicator continue to be the most reliable way to catch fish, though chironomids, damsel nymphs, and callibaetis nymphs can be excellent as well, either under an indicator or on the strip. Fluorocarbon is a necessity for subsurface presentations this time of year. Fish along the edges and in structure. Getting 15 feet deep isn't as crucial this time of year as it is when the water is hot.
