Anadromous salmonid escapement and downstream migration studies in Prairie Creek, California, 1995-1996: 1996 progress report
Roelofs TD and Klatte B. 1996. Anadromous salmonid escapement and downstream migration studies in Prairie Creek, California, 1995-1996: 1996 progress report
In monitoring long-term effects of excess sediment added to Prairie Creek during 1989 construction, these researchers surveyed adult and juvenile salmonids from December 1995 to February 1996. A record number of carcasses and redds were found, and juveniles migrating downstream were estimated at twice the number of 1994, probably partly due to higher winter flows. However, some redds tested had no fry emergence and the report states that "fine sediments continue to be a limiting factor for egg incubation and fry emergence in Prairie Creek". The report includes a map of impacted creeks and trap locations, statistics for fish migrating upstream, spawning and carcass surveys, totals by species for juveniles migrating downstream, length frequency histograms, and fry emergence as related to permeability.
