A Summary of Juvenile Salmonid Trapping in the Lillooet Lake Catchment, Including Lillooet and Birkenhead Rivers, 2010.
While the presence and spawning habits of chinook salmon (Oncorhynchus tshawytscha) in the Birkenhead River have been thoroughly documented, little is known about chinook abundance and distribution in neighbouring rivers in the Lillooet Lake watershed. Minnow trapping was conducted in various streams throughout the Lillooet Lake watershed in Spring 2010. Juvenile chinook salmon were captured in the Lillooet River and several of its major tributaries (Ryan River, Railroad Creek, Miller Creek, Green River, and Gravell Creek) as well as in the Birkenhead River and Joffre Creek. Juvenile chinook were captured in many areas and as late as was March 22 while subsequent trapping (as late as May 26) did not capture any juvenile chinook.
