Some of his descriptions on the O.M. Stonei, aka redband rainbow trout of northern Sacramento drainage which are lacking in your photos; orange and white tip on the dorsal, fewer spots below the lateral line and the red slash typical to cutthroats.
Steelhead gear = $6287, no of adults caught = 3, amortized cost = $2,095.67, beaching that 30" fish and letting it go = priceless
