Johns Creek.—In both 2003 and 2004, large numbers of juvenile Chinook
salmon were present in the index reach of Johns Creek in February and March (Figure
33). Peak abundance was 632 Chinook salmon on March 5, 2003. Numbers gradually
decreased from late March through May and few Chinook salmon were present by the
beginning of June. In February, the mean length of juvenile Chinook salmon in Johns
Creek was approximately 40 mm FL and by the end of May they averaged 74 mm FL
(Figure 34). As they grew they used progressively deeper areas of the creek, from 0.28 m
in February to approximately 0.5 m in May (Figure 35).
