The wild summer Steelhead is the most magical freshwater fish.
I personally believe that hundreds of rivers from California, Oregon, Washington and British Columbia had summer Steelhead before the dams.
Rivers come back naturally with no dams, no hatcheries, no development, no AG, no logging, no mining, and no commercial fishing.
Supposedly the summer Steelhead come into the rivers in the high water of Spring, go up to the deep shady spring feed holes and spend the summers
up there and then spawn in the Fall and then most return to the ocean.
The Middle Fork of the Eel river near Covelo had the largest size and amount of summer Steelhead in California.
