As Bill’s experience with rising water on Tuesday reinforces, the best fishing is to be had on stable flows, whether its minimum flow or not, try to avoid fishing the sudden bumps in water level, as they tend to be very dirty. If you find yourself in dirty rising water, travel down river to stay ahead of the “push”, or head upriver until the flows are clear and stable again. Various caddis pupa, prince nymphs, and other green-bodied nymphs continue to produce well, as do green soft hackles like Dally’s Tailwater Soft Hackle in caddis green, #14 and #16. When the caddis aren’t popping, try a dark or grey Wotton sowbug or olive Hunchback scud with a small midge for a trailer. Use Zebra midges, Harvester midges, Ruby or Root Beer midges, or Wotton Super midges. San Juan Worms are a good idea too with the major fluctuations in water flow, especially if you cannot avoid fishing dirty water.
Low flows are fishing well with midges, scuds, and sowbugs. Fishing near structure and drop-offs in the deeper pools is key. Suspend your flies mid-watercolumn to start, then work deeper as necessary. Takes will likely be very slow and subtle. A slow swinging soft hackle in the riffles and tailouts is also deadly. Try Anna K’s, Dally’s Tailwater Soft Hackles, and various partridge hackles. Don’t be surprised if the waters get a little crowded this weekend. Normally 6x tippet isn’t necessary around here, but on Memorial Day weekend a little stealth and 6x might be a difference maker.
