September 21, 2016
Before the colder rainy overcast weather forecasted for the next three days, fishing on the Double R had settled into a pattern of bugs coming off starting round 10:00 a.m. and rising fish lasting until late afternoon. Yesterday, fish were working well into the evening on The Pond and from the spillway down to Beat #5. The main insect culprits were #18 Callibaetis, Tiny Blue Winged Olives (#22-22) and some legitimate Fall Baetis (#18). Other bugs are beginning to make their annul appearance.
Keep a lookout for #14 Caddis with ginger/amber bodies. These caddis are not really the classic October Caddis which one encounters on freestone streams all over the Northwest. Nevertheless, any sparsely tied October Caddis pattern will do nicely, as well as an appropriately colored X-Caddis, Troth’s Elk Hair Caddis or the like. The porch light has attracted these caddis onto and into my trailer.
This week I ran into an aquatic insect which I had not seen previously on the Double R. I’m not saying that it is a “new” insect on the Double R Ranch stretch of Silver Creek, but it is new to me. I’m talking about lime green stoneflies. I’ve seen one adult and one nymph at the entrance to Beat #7. They are about the same size as the Yellow Sally stonefly. There is no reason for these stoneflies not to inhabit the Double R now that we’ve cleared out a bunch of silt and the water is consistently cold. It would be pretty amazing to have a fishable “hatch” of these little stones.
I have been anxiously awaiting a fishable hatch of Mahogany Duns. These relatively large mayflies (#14-16) are a welcome relief after months of fishing smaller insects. I haven’t personally observed a Mahogany dun yet but Members have reported seeing a few of them here and there on the Double R. My journal indicates that last season I first spotted Mahogany Duns on September 15 and a dense hatch on September 27, so we may be right on schedule. The next three days of cold snotty weather might well bring on the Mahoganies. I’ve got my Mahogany Dun fly box restocked and in the float tube. I can’t wait.
