Sun Valley Area Fishing Report - September 1, 2015

August 31, 2015 / Picabo Angler

RED. When it comes to fishing, Red is the color for fall. Whether it is the Western Red Quill gracing the Big Wood and Upper Lost, or the Red Scales of the Kokanee that will be migrating up the rivers from local reservoirs, to the Redd’s that Brown and Brook Trout will be making and even the Red of the eggs from spawning fish, Red is the color to focus on.

We are entering a transitional time of the year on all our area waters, as summer hatches begin to wind down, and the fall hatches begin to ramp up. On Silver Creek the Trico Spinner Falls are beginning to wane, while the Baetis builds in numbers. Grasshoppers and Mice are taking the biggest fish, while Callibaetis continues to show up on occasion sparking serious feeding frenzies. Watch the weather as the Creek transitions to banker’s hours. No need to get to the water until the air temps warm up after cool nights. Be ready for midday Baetis hatches that can fill the afternoon hours with bugs and fish galore!

The Big Wood continues to muddy then clear, muddy then clear. The Red Quills will be coming soon, as well as the Fall Baetis. Watch as the leaves begin to turn. When they start falling from the trees the Western red Quill is typically in full swing. The Colorado Green Drake is the best fly you can use for the Quill hatch, and we stock this fly for the fall, just for this reason! The Green Drake of June and the Red Quill of September are very similar in size and color, making the Drake patterns a great choice for one of the most overlooked hatches in the fly tying industry.

The Lower Lost continues to be tough wading, although keep an eye on the USGS website for current flows. Once you see the river drop below 300CFS, plan on heading over. Red colored nymphs like Copper John’s and San Juan Worms are deadly when the Kokanee get swept through the dam.

The Upper Lost continues to fish well with Ant and Hopper patterns, but at current flows, be prepared to walk a lot. Trico and some Pink Albert are present.

The South Fork of the Boise will also begin to transition between Pink Albert and Hoppers to the Fall Baetis hatches soon. Mother Nature will dictate these changes with cold nights.

Anglers need to be prepared with both, summer and fall bugs right now in order to take advantage of what happens with the weather. Also a great time to bring those extra layers of clothes to the river!

Happy Fishing Everyone!
