California Department of Fish and Wildlife 2015 Chinook Salmon Redd Survey Report
The California Department of Fish and Wildlife has completed the 2015 Chinook Salmon Spawning Report which covers the years 2012 through 2015.
Some of the data in the study is outdated or inaccurate. For example, the Auburn Ravine has never dried up. It always had many tributaries and countless springs feeding it and still does. The Auburn Ravine was and is a year round ravine. Yet, for years fish scientists mistakenly classified it as an ephemeral stream.
