Topic Fish: Chinook (Fall) Trinity In-River Run Size above Willow Cr 1977-02
 
Caption:  Trinity River fall Chinook run size above Willow Creek has been estimated by the California Department of Fish and Game since 1977. Grilse are also known as jack salmon and are generally precocious males that have spent only one year in the ocean. Counts are made by intercepting fish at a counting weir at Willow Creek and marking some animals and using mark-recapture techniques for run size estimates. In-river sport harvest in the Trinity River may make actual escapement less than the values shown above (see previous Topic). These data may not reflect Lower Trinity main stem redds and Hoopa reservation tributaries for years before 2002 due to method of aggregation of redd counts by CDFG. Please note that the data for year 2002 are provisional (draft). For more information and a link to the CDFG reports see Info Links.
