Where my son is standing, on the East Walker River, the depth averages 3 1/2' - 4 1/2' when the flows are at about 340cfs. - in other words, that water is moving quite quickly...
He is using a 10', 5wt Loomis Streamdance rod. The leader is 7 1/2' 4x with a tippet ring, 24' of 4x to the point fly,which has wraps of lead wire and tungsten bead and 18"-24" of 5x tippet off the bend of the point fly, to the dropper, which may or may not be weighted...We generally use small(yes, SMALL #18-#22) midge, Baetis/BWO, Caddis (nymphs or larva) at this time of year, on that river (late May)- as the dropper
We use lead twist-ons and not shot. In this case , he is using 2 1/2 - 3 twist-ons, spaced 3" apart above the point fly depending on the depth and speed of the flow of the particular spot he is working... we break it down into small sections and work the water at our feet before
stepping in the river. Neither do we use long casts...the Trout in here are not looking up. One's flies must
be 1"-6" off the bottom, when using the above patterns...if we are not hanging up , from time to time, we will not be catching fish...
I have fished that water when the flows have been 940cfs....one doesn't wade too far out and it may require 5-6 twist-ons to get one's flies deep. That is when a 10' rod really shines!
