| Notes | “This report provides a summary of results from winter steelhead spawning ground surveys conducted in Lower Columbia (Oregon side only) and Oregon Coast basins in 2018. Also included is a brief summary of lamprey data collected from the same monitoring efforts. . . Total winter steelhead redd estimates were approximately 98% of both the 5- and 10-year averages for the Oregon Coast (OC) Distinct Population Segment (DPS). . . Regional patterns are apparent for winter steelhead redd density, proportion of hatchery origin spawners and spawn timing. Indices for Pacific Lamprey were lower in 2018 in the Lower Columbia compared to recent years, but above average in the Oregon Coast.” (p.1) Statistics are not given for Individual sites on the Oregon Coast other than the Umpqua River and the Nestucca River. |
