We are seeing conditions similar to August here right now.?? Mammoth Creek is low and not adding much water to the spring's level.?? Conditions are good now but as the summer rolls on we will see the weed beds protruding the surface making presentations more difficult in the channels.?? Caddis and midge patterns are solid choices.?? WD 40's, thread bodied midges and olive dubbed crystal zebras will get you grabs.?? I like to clip the tails off of our zebras at times, especially during low, crystal clear water conditions. I suggest you fish as small a nymph as those aging beat up old eyes will allow you to tie on.?? #18 is a jumbo imitation currently with better results on #20-22.?? When the fish are stomping the caddis, #20 dark bodies on top things get infinitely easier for the adept casters and menders.?? 5X is suicide unless it is overcast.?? Have some 6 or even 7X for more takes.?? Cast to them, do NOT walk and wade please!
