Recent in-river returns of Trinity River Hatchery (TRH) steelhead resulted in increased concern that the numbers of hatchery fish returning could negatively impact naturally produced steelhead in the mainstem and tributaries. In 2009, adult hatchery steelhead were tagged at TRH and at the Willow Creek weir. Hatchery steelhead were detected straying into Deadwood Creek, Rush Creek, Browns Creek, and the North Fork of the Trinity.
