Water Monitoring

San Simeon Creek riparian corridor

Since 2003, Greenspace staff and volunteers have been actively monitoring the water quality and condition of our local creeks. With funding from the Morrissey Family Foundation, we purchased state of the art YSI water monitoring equipment with probes for salinity, oxygenation, ORP, pH and other factors in order to get basic monthly readings from sites on Santa Rosa and San Simeon Creeks. These readings enable us to determine the basic condition of the creeks and whether conditions are hospitable to steelhead fish and their young fry. 

Our Coalition

Greenspace is a member of the San Luis Obispo County Water Conservancy, a coalition of local non-profits and agencies that work to improve the condition of our local waterways. We are working with fellow Conservancy members Central Coast Salmon Enhancement and Upper Salinas-Las Tablas Resource Conservation District to develop Citizen Science projects for monitoring water quality and stream flow in Santa Rosa Creek and Lagoon, and for annual fish counts to determine the creek’s current steelhead population.  

Past Projects

Our past projects have included removal of steelhead migration barriers under Cambria’s Burton Street Bridge, reconstruction of an eroding streambank and rerouting of Santa Rosa Creek into its earlier streambed, and design of a bridge for Ferrasci Road, east of Coast Union High School, to replace a culvert that made fish passage impossible when the creek levels were low. These projects all were made possible by grants from California Department of Fish and Wildlife/Fish Restoration Grant Program, which also funded our Santa Rosa Creek Watershed Management Plan.
