This polyline shapefile provides temporal data on the size and growth rate of juvenile salmonids from Santa Rosa Creek, a tributary of the Russian River, which were monitored over eight rearing seasons (1994-2001). Monitoring was conducted at the beginning (July) and end (October-November) of the summer dry period to enable estimation of juvenile growth rate.This dataset was conducted to evaluate spawning success, fry or fingerling production, and juvenile survivorship as part of a larger study examining the potential effects of reclaimed water discharged to Santa Rosa Creek by the Santa Rosa Subregional Reclamation System.
