[ARCHIVE] Boulder River Report – 05/06/19

It looks like a window to fish before runoff will remain through the week. Flows dropped and are relatively stable. There should be some dry fly fishing opportunities won the cloudy, overcast days. Look for BWOs and March Browns to be coming off. A Purple Haze will almost always get the job done with rising fish. A size 14 for March Browns and smaller sizes for BWOs. If there are heavy rains and the tributaries kick in off color water, nymphing along the edges is probably the best bet with a rubber leg nymph pattern like a girdle bug, Pat’s rubber legs in black, brown or coffee color, or a san juan worm, along with a beadhead trailer fly like a prince nymph, hare’s ear, batman or pheasant tail. Look for Caddis coming off, and if the fish are on them, try a darker body size 14 for the dry fly and a size 14-16 green or olive pupa or emerger. Also try basic buggers in black and olive or the Grinch for streamers. At some point soon, the river will start running high and off color and will be best to just stay away from it.
