Adult Run-Size Estimation

Run-size estimates for Trinity River spring- and fall-run Chinook salmon, coho salmon, and adult fall-run steelhead are made annually above two mainstem Trinity River weir sites at Junction City and Willow Creek. Total adult run size includes harvest, natural area spawners (escapement), and hatchery spawners for the areas that are monitored. The spring Chinook salmon information does not include harvest that occurs below the weir or spawning that occurs in tributaries such as the South Fork Trinity River, North Fork Trinity River, and New River. Due to the mixing of naturally produced and hatchery produced Chinook salmon in the natural escapement, the escapement estimates and Program goals for natural escapement are not directly comparable.
