Lower Yuba Fly Fishing Report

The Skwala stoners are out, a little early but not by much. I was surprised to see as many shucks as I did over the past two days. They’ve been pre staging in the idle slack water downstream of riffles over the last month. Many of my clients are put back by how small the Skwala stonefly is compared to Goldens, and Pteranarcys. Your flies should be close to the same size for both the nymph and the adult. You can see here a stillborn that started to emerge, than failed. I’m surprised the birds didn’t get this one. It’s good to see the songbirds once again, my old friends are back on their favorite perches waiting to intercept passing aquatics in the breeze. Black Phoebes, Ruby Crowned Kinglets, Yellow Throated Warblers, and Townsend’s Solitaire in the mix. If you see birds starting to dart back and forth from their perch, you can anticipate that a hatch is about to go down, while putting yourself in a good run and waiting for the trout to respond. Mother Nature will provide the clues if you stop casting, and observe more. Skwalas are most active during warmer air temps and are in the foam and bubble lines in the afternoon. The majority of the fish are not keyed in on them yet, but they will be. I’m hoping the river does not blow out like this year and continued for months. We had serious game last January on the surface until February came along, and you know the rest of the story – Whooosh! Mating has already started. Stoneflies live a long time for an aquatic bug and can mate several times, unlike a mayfly. I also like to point out how much bigger the female is compared to the males, having two sizes of both nymphs and adults can up your odds. #12 2xl for the male, #10 2xl for the female. Check out my article in the December 2014 issue of California Fly Fisher magazine for the complete details on the Skwala hatch. I really dug deep with the information shared on this one. There have been decent hatches out, nothing profuse but that should change here in the next month. Many different mayflies including the big Brown Dun (Ameletus) #10, BWOs #18, PMDs #14, and Pinkies (Epeorus) #16. Yesterday after noticing the birds eating rapidly from their perches, we put ourselves on a good flat and sure enough we had BWOs coming off and multiple rising fish. Unfortunately, the show was over in 20 minutes. There is also a sprinkling of micro caddis out as well, but mayflies taste better to the wild rainbows. The weather looks to be perfect in the next week with a mix of sun and clouds, plus a chance of light rain on Saturday. It’s all systems go for the Lower Yuba River, and the fishing will only get better once the fish figure out the Skwalas are in the drift during the afternoons – Looking forward to that! See you on the water…
