This polyline shapefile provides temporal data on the size and growth rate of juvenile salmonids from Maacama Creek in the Russian River Watershed, 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.
