I am probably going to be torched on here for asking this but I am a service member just recently stationed here in Oregon. Last weekend I went camping with the family up in Idahna on the North Fork, was tossing a Rooster Tail and hooked into what I was certain was a Steelhead. I caught a couple glimps' of it and yes I have caught numerous Steelhead in the past. I was fishing with 8lb line on a pretty decent trout rod so worked the fish pretty slow trying not to loose it. After about 20 minutes or so it shook the hook. My question is, how the H#LL does a Steelhead get above Detroit Lake or am I delusional on what I was hooked into? I am soon leaving for deployment so sat by the river just taking in the sites for quite a few hours and throughout the day saw numerous pretty large fish flip around at the bottom of a wash out to eat. To me they looked like spawning chinook but again, how do they get above Detroit Lake? They were very large, black sillouetts that seemed to have a white head or jaw tip. Any info would be nice, thanks.
lbc007,
I know the answers to your questions. Where to start? Okay. Some history first. You're right in that there are no fish passage devices downstream at Big Cliff or Detroit Dams. Downstream from Big Cliff is the Minto Dam fish trap, which is operated by the ODFW Marion Forks Fish Hatchery upstream from Idanha. They collect Chinook and Steelhead at Minto and truck the eggs up to the hatchery, where they hatch 'em then later take them back downstream to dump 'em in below Minto.
Back in the late 1950's they had an accidental fish spill at the Marion Forks Hatchery and somewheres in the neighborhood of 70,000 baby Chinook Salmon got released into Marion Creek, which feeds the hatchery. The salmon swam down Marion Creek into the North Santiam and hence into Detroit Lake. What surprised ODFW was the fact that a few years later LAND-LOCKED Chinook started being caught in Detroit. Apparently the salmon found Detroit Reservoir ideal. The Chinook that stayed in Detroit Lake found a great enviroment for themselves. Since Detroit Lake is NEVER emptied but lowered after Labor Day down to what is called minimum pool, the Chinook had a lake/ocean type of enviroment year-round. ODFW discovered later that the land-locked Chinook started swimming up the Brietenbush and North Santiam to spawn in the fall, like the Kokanee do in Detroit Lake. Boulder and Blowout Creeks also may have runs, though smaller due to the size of those creeks.
Now that fish you hooked and the others you saw are most likely native or wild rainbows, since it is too early, as far as I know, for the Chinook to be upstream getting ready to spawn. There are some big-ass rainbows in the Brientenbush and North Santaim upstream from Detroit Lake. I've caught 'em up to 25 inches long up from Idanha. They live in the rivers there. And I'm fairly sure any trout over 20 inches that you might catch upstream from Detroit Lake are NOT considered steelhead, due to the location of the streams. Steelhead canna get up that high from below Detroit and Big Cliff Dams, therefore the "any trout over 20 inches in streams" rule does not apply. Look at the Sport Fish Regs yourself.
Hope this is helpful. Come back from overseas in one piece, God willing!
