Distribution and habitat use of juvenile Feather River salmonids: 25 years and ongoing of snorkel surveys

Since 1999, the California Department of Water Resources (DWR) has
conducted annual snorkel surveys to monitor juvenile salmon on the
Feather River. The objective of this data collection effort is to
determine the relative abundance and distribution of rearing
juvenile Chinook salmon and steelhead. A secondary objective is to
collect baseline data for future monitoring programs associated with
habitat restoration projects. Crews survey units within 20 sampling
sections on the high flow (HFC) and low flow channel (LFC) between
January and September and collect information on species, fish size,
substrate, cover, and habitat type. This dataset represents an
extensive time series that could be used to identify habitat
conditions where juvenile Chinook salmon and steelhead occur and how
these conditions have changed over time. These data were published
to support the Healthy Rivers and Landscapes Program.
