Adult Monitoring Information


Salmon spawning ground surveys have been conducted each fall since 2012 to monitor the distribution and abundance of adult Chum Salmon returning to the Lower Columbia River. Additionally, from 2016-2019, an adult fish trap was operated on Stewart Creek in the Clatskanie River population to evaluate Chum Salmon fry survival from adult outplanting efforts in the creek from 2013-2015.
