That time of year can be gangbusters in the tailrace…but it can also be very busy if you fish Fri or Sat night….a little less busy during the week. If you want to hit it at the best time…go for an early AM bite (like dump the boat in at 4am and head straight up the shoot towards the dam). It is safe running from the boat ramp up into the shoot….if you go south of the ramp, things change fast. Take a spotlight with you if its your first time to help you get your bearings at the ramp…once your up in the chute, there is nothing to worry about hitting other than other boats…there is quite a bit of light up that way from the dam.
Take a long handle bait net with you (like a bait net on a 8ft broom handle). It is legal to dip the stunned smelt off of the surface an use them for bait there. Have a 3-way rig tied with a 1/2 or 3/4 sinker on one end (most of the time 3/4oz is best for staying vertical but can depend on releases) and a #2 or #4 plain hook on other. Tie the weight onto the 3-way with very light lb test (4 or 6)…if you snag up, will just lose weight then. I say go early before sun-up because you can get the smelt off the surface up below the dam before the birds can see them and move in for the day.
There are big orange markers on both sides of the chute (rocked area that runs up to dam) that tell you how close you can get to the dam. Pull up to those…put your motor in neutral and let the current start to drift you. Run that 3 way straight down and try to stay vertical…if you feel bottom, reel up and stay a foot or 2 off bottom. If you dont have smelt, can use crawlers, smelt colored plastics or Rapala F-11s…they all work but the stunned smelt will out fish everything. The drifts will be fast and have always caught most fish in the first 1/2 of the drift….when you get the the end of the rocks, can fire the motor back up and run up and repeat. You can fish jigheads too…1/2 to 1 oz….just have to figure out the drift based on the release at the time…it will change while your there too. Like was previously stated…DO NOT Anchor in the chute…bad idea. Saw a boat do this one time and when the rope tightened up, they had problems….not to mention the other boats drifting past them at mach 5.
Fun part about that time of year is you do not know what you have when you set the hook. Lots of catfish but also have a legit shot at some monsters. Walleyes can be hit and miss…when its good, its insane. Best part is, you have the chance at the big Rainbows and Browns… have pulled a 14lb rainbow, 16lb brown and 7lb cutthroat form there and those are not near as big as they get. Plus, can get bonus Salmon, ling, and just about everything else that swims in the system. Its just fun fishing.
If you have to fish evening…just going straight south of the ramp on the sandbar flat and anchoring up in 4 to 7ft and tossing floating cranks in the evening is great too…used to spend my summers driving up there with my waders and fishing there in the evenings. Can fish the evening in the chute too but it will be busy in there if the bite is on…can get a little hectic with all the boat wake…wear your life-vest.
