Icy from Golden to Idaho Springs and beyond. The only guaranteed ice free water is right downstream of Georgetown, and in town in Golden. Everything else is thick with ice and unfishable or too difficult to fish. Look for March to be a good month to find open water on Clear Creek. When she does open try stones and mayflies fished deep in runs and tail outs of pools. When the ice starts to open up, nymphing will be best until the hatches start later in the year. Closer to the town of Golden is usually warmer and can start to fish in February during warm spells. The tunnels on highway 6 are good spots to hike away from the road for anybody who doesn't want to hear the traffic.
