Trout return to San Pablo Creek!
December, 2016. It has been many years since rainbow trout were spotted in San Pablo Creek in Orinda – until last week. For over ten years, Fisheries biologist Brain Waters and Wildlife biologist Professor Reg Barrett have maintained that San Pablo Creek in Orinda is potential habitat for rainbow trout. They were proved right after EBMUD reported over 100 trout ranging in length from 10-14 inches near the Orinda Filter Plant. This occurred shortly after EBMUD cleared root wads and other debris and removed the metal obstructions in the sluice gate opening of the small (12-foot high) dam just upstream of Bear Creek Road - in time for rainbow trout to swim upstream for spawning season.
Besides the pleasure of seeing these large fish swimming in our creeks, they are one of the best indicators of creek health. Friends of Orinda Creeks (FOC) has been in negotiation with EBMUD for many years to see this happen and pressed for providing an opening for fish and regular maintenance of the dam.

During October and November, 2016, two students from San Francisco City College, Madalene Velasco and Virginia Urzua-Rios, conducted a four-week creek monitoring effort in San Pablo and Lauterwasser creeks. City College Professor Ying-Tsu Loh has supervised their work throughout the program. They have done meticulous sampling, testing, and recording for parameters such as Ph, temperature, dissolved oxygen, nitrates, phosphates, coliform, and nutrients. This work has taken place at a total of six different sites along the creek. All of the data they have collected will help us assess the health of our watershed and how well it can support aquatic wildlife. We are very lucky to have these two hard-working students are very grateful for their tremendous efforts, often performed during difficult weather conditions. We have high hopes to continue this partnership into the future.Type your paragraph here.
On Friday, April 29, 2016, Friends of Orinda Creeks installed a brand new interpretive sign in the Orinda Community Park near the tot structure. It features pictures of San Pablo Creek in downtown Orinda, local wildlife, a map of Orinda's watershed, and information about the creek. The sign was produced and installed in partnership with the City of Orinda.
