Saturdays during the fall salmon run, a team of CWCAP citizen scientists collects data from salmon carcasses in the Piper’s and Venema Creeks, while another team systematically records live sighting and spawning activity data.  Each fall, CWCAP surveys each salmon carcass to determine whether fish are fully spawned, partially spawned, or not spawned at all (view salmon return numbers since 2014).  This is one measure of the heath of the adult salmon return. Through early-mid December, CWCAP will be conducting Saturday surveys (Nov 10, 17, 24, Dec 1, 8, 15) until no more un-sampled salmon carcasses are found.  Around Thanksgiving time has been within a few days of the actual peak of live activity for at least the several years.

Salmon carcasses are sampled for a variety of standard data measurements.

The following table summarizes the carcass and live results for Fall 2018.  For more details and survey results from 2014, 2015, 2016, 2017, and 2018, please visit the Salmon Spawning Surveys page.
