There are quite a few threads with gear set ups, and locations, but now the Coho threads are so convoluted, and there are so many posts it is hard to sift throught all the banter, to try and find exactly what you are looking for...
Unfortunately most of the publically accessible land to fish will be crowded, especially on the weekends. Bonnie Lure Park is good, parking is just after the Dowty Rd. bridge. If you hike down below the combat fishing, you have much better odds of getting something to grab your stuff. Remember Coho are most aggressive in faster riffles, and chutes where a volume of water is forced through a channel, or rocks, and it creates higher hydraulic pressure. They are more apt to strike in the fast stuff, but a lot baseball fishing is done in the slower, deeper holes, as many fish pool under the log jams to hide. Small is key right now, no terminal tackle, either, use bait, or bait immitations. Small egg clusters, and small egg patterns, or skein immitations are killer. Tiny bit of split shot, maybe a few grams at most. Short leaders too, like 12-18 inches You will be sight fishing for most of the fish in the creek if you are angling the correct waters. Watch what the fish do when your drift is done correctly, see if they get spooked by it, or if they kind of give it a glance, bring it in closer on your next pass, and normally it will piss them off just enough to hit it hard. Lift up gently and "feel" the fish, then just tug a bit to make sure your gear is set. Swings to set your stuff is no good, and kind of dangerous if you happen to pull out gill plates, or large chunks of meat. It is all to common to get a fish from the Creek that has just been beat down. Imbedded hooks, and all. Missing gill plate chunks, gnarly hunks of dorsal meat missing, you name it, they get beat on through the gauntlets. 4/0 Owner trebels with bait loops for 4" hunks of chartreuse yarn! Woah! If you run yarn, go number 4 hooks, and pieces of natural-ish colors, like black and light pink, or apricot, the size of your pinky nail. Little scent maybe? try a lot of stuff, and find what works for you, because my gear works for me, and other friends have better luck on different presentations, try everything you've got, surely you can get a freak to come and hit your presentation. Be prepared to have a bunch come unglued, it happens a lot, ad the Coho are a crafty bunch...Extra smart, and seasoned to everything by the time they get up to Eagle Fern. There is a fair amount of work involved to get one to hit, and the chase just makes it harder, but when you find them moving, your efforts will be rewarded. The fight is so fun, they will take you for a ride. Upset these Coho become after so long stewing at the mouth, getting harassed and seeing thousands of gear setups on the way to finally get fooled by yours. Feel grateful if you got one tricked. If you think about it, the chances of hooking one is slim, but luckily there are a bunch of fish, so your odds are greatly increased. Good luck man, and don't fret if they ignore you, it just takes time, I got skunked a lot, and still have days where I just can't persuede one to stay on the end of my line. Those wiley Coho. WHEW, enough said, hopefully that will get you started in your many Coho expeditions, the info is hard to find, I know, but maybe this will help a few on the right path to angling the Creek... It is what works for me anyways...
