In searching previous years posts some say the Springtime higher dam flows will move the fish 20+ miles upstream. Have you noticed sometimes the bite is best trolling upstream closer to shore? There is current especially when outflows are high, and current definitely changes Kokanee behavior. Study river flow, time of year, and compare to angler success and where. Take opportunities to question fisheries biologists, especially the ones actively researching Dworshak kokes. Outfitters and guides sometimes share info when asked. The outdoors is where they pay their bills so you can bet they've done their home work. Seems like I've read some of their posts, or referrals to their web sites and articles on this forum. Good stuff, and appreciated!
There were an estimated 60,000 adult kokes last year, 250,000 this year! Hope to be on the water there in a couple weeks.
