The "residual" run of steelhead that many of us are convinced are remnants of the original native steelhead run are not "romantic notions" but based on irrefutable facts.
Now, if you are talking about the half pounders that are caught in the winter, slender immature steelhead from 10 to 14 inches, or the run of football-shaped brightly colored rainbow-looking fish that are caught in August/Sept. I won't argue with you.
But many of us fish for steelhead in the early spring months--middle of Mar. well into April and have been doing so since the 1960's. Those fish are mature adults (very tiny eggs, but would spawn before returning to the ocean), deep-bodied and 3 to 5 pounds.
The proof? DFG's Eric Gerstung wrote a report study of these fish in the early 70's and listed the hatchery return numbers by month starting wiht the first year that the dams were finished. Any returns those first years would be natives. NO steelhead entered the hatchery until March and the run continued through April. It was because the numbers were small and got smaller in subsequent years, that the Eel River straiin was introduced. For many years, DFG ignored this remnant native strain taking all the eggs they could early in the run until they reached capacity, then stopped taking fish, some years as early as Jan. A number of people, me included, were successful in getting DFG to spread the egg take.
Gerstung's report also gives a fascinating history of the AR's steelhead run pre-Folsom/Nimbus dam, pointing out that there was a substantial steelhead run before the power facilility was built in Folsom. There was a fish ladder, but it was washed out in floods and not rebuilt. Still, a remnant of the original run hung on struggling to get past the barrier to the tributaries high in the system.
Further, there was also a spring fishery of what many were convinced were steelhead trapped in Folsom Lake at the inlets (No rubbed fins, silvery) which hasl largely disappeared.
It is unlikely that steelhead came up the AR in the fall, because, as was pointed out, flows pre-dams were very low and warm in the fall until the rains arrived. BTW, I do have a copy of that report somewhere. Perhaps it would be worthwhile to make a copy and get it to Bill for others to be able to look at. It was a great effort and gives great insight to the history of steelhead in the AR and the failings to protect AR fisheries early on.
