I am not surprised the UPPER OWENS RIVER during the initial days of the new regulations has been downright SLOW.?? My scouting before the start of the season did not discover large concentrations of fish at that time.?? We did get locate some pods of fish but they are spread out and require a lot of scouting to find.?? The weather has improved greatly this week and is forecast to warm significantly in the future.?? Look for a substantial migration of rainbows to begin moving up from Crowley (which happens to be ice free and very full) this week becoming more prevalent as the month goes on.?? Use a San Juan Worm and an olive bead head zebra, PT or hares ear #16-20 as a dropper in the pools while nymphing.?? Bwo and caddis activity #18 during the mid-day periods for those who want to fish dries.?? Streamers like the Loeberg and Spruce-a-bu will also do well as the spring unfolds.?? You will need a moderate sink tip to get those patterns down under the cuts in the banks.
