SARSAS Citizen Science Program – Coordinator is Bob Johnson at johnonb1524@gmail.com or call him at 530 262 7036.

The SARSAS Citizen Science Program currently conducts surveys along Auburn Ravine every year between October 15 and April 15 which is the time frame in which Salmon and Steelhead are able to migrate upstream to spawn. Each week, volunteers go to designated areas to count Salmon and Steelhead. They record their observations at www.inaturalist.org along with information about water and air temperature, the clarity or turbidity of the water, and other data.

The advisor for this program is salmon authority Dr. Peter Moyle of the Center for Watershed Science at UC Davis. This program provides documentation on migration patterns of salmon and steelhead, water conditions, and the overall health of the Auburn Ravine watershed. We are always looking for more volunteers to do these observations so we can cover more areas of Auburn Ravine.

Eventually, we hope to expand into a full-year program using Spark water quality test kits so we will have a complete picture of water conditions in Auburn Ravine. Each observation takes between 30 minutes and 1 hour and is usually done on Sunday afternoons. If you want to feel the excitement of seeing wild salmon surge upstream, volunteer for this program.

    I was greeted by four peacocks today at the Moore ranch. I did not make an observation last week due to the storm. The water level is higher than two weeks ago and the banks show indication of an extremely high stream flow with debris scattered high up all along the streams banks. In one area where there used to be a side channel from the main stream, a 60' stretch of the water is now covered by 10 inches of silt and gravel. The stream turbidity is also greater than that of a day previous during SARSAS training near the gauging station. […]
