Tahoe,

I've seen and heard of great creeks and small rivers draining into Cook Inlet directly north and across from the Kenai Penninsula. More or less directly across from the city of Kenai if you were to use a ruler and go do north across the inlet/salt H20. Supposedly most of the small streams there carry healthy numbers of coho running in August & September. You might be a little early on some of the coho. Check with a local...A guide outfit/resort by the name of Alaska Fishing Adventures knows many of the places there. They are based in Kenai in the summer and here in Poulsbo during the winter. You can probably find them on a web search engine. I don't know if they'd share secrets spots with you but you might get a little beta -or if you had enough funds to give you a days outing with them -they will deliver the coho goods! Those guys slay them with flyrods!!!!
Good Fishing, Darin
