A PAIR of steelhead trout spawn in a pool on the north fork of Mill Creek over the weekend. Fifteenmile and Mill Creek are home to the easternmost population of wild winter steelhead in the Columbia Basin, and represent the edge of the range for the winter-run life history, according to a 2007 report by the Wasco County Soil and Water Conservation District. Hatchery fish have never been introduced to either stream, making the runs genetically valuable for the long-term survival of the species.
