SCL - Spring Creek NFH Adult Ladder

Fish ladder allowing passage from the Columbia River into the adult holding ponds at Spring Creek NFH. The adult fish ladder at Spring Creek NFH is operational from late August through early October annually. The detector is approximately 60 meters up the adult ladder and is comprised of three antennas located in separate ladder cells. All fish entering the facility from the Columbia pass through the antennas and after ladder navigation are sorted and may either be either surplused or spawned. Some captured adults are returned to the river from the spawn collections (adults with adipose fin present and no coded wire tag). Released fish are passed through a tube that empties into the Columbia River directly upstream the fish ladder entrance.
