Sluice gate opening when clear, which is not very often.

Dam under normal circumstances, with sluice gate opening clogged and debris built-up forcing water over the top and forming a barrier to unimpeded upstream fish movement.

Will Rainbow Trout Return to

Orinda's Creeks?

Perhaps you have seen the January 2016 article in the Lamorinda Weekly  The small barrier dam, referred to as SP201, was built decades ago on San Pablo Creek, just upstream from San Pablo Reservoir and above the Bear Creek Road crossing. It has a small rectangular opening, called a sluice gate, at its base, shown in the first photo when it was clear of debris. A lot of tree branches, debris, and mud, moving downstream from storm run-off, back up behind the structure. As you can see in the second photo, this debris easily clogs the opening, backing the water level up and over the top of the dam. This forms an impassable barrier for any fish migrating from the reservoir and up into the creek to spawn and to live out their life cycle. If you are enthusiastic about the possibility of trout re-inhabiting the creeks, let us know. Send us your thoughts. We welcome community support to encourage East Bay Municipal Utility District to help us with this goal. You may also email EBMUD director Marguerite Young ( to express your support.

​​Our New Interpretive Sign!

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. 

Coastal Cleanup Days in Orinda 2016

Orinda participated in National Coastal Cleanup Day with a huge, three-site success.

On Tuesday, September 13, Miramonte High School teacher, Barbara Denny plus 90 capable students cleaned up 36 pounds of trash and recycling from Moraga Creek.  

On Thursday, September 15, Del Rey Elementary teacher, Marta Wallace, Friends of Orinda Creek's president, Jim Luini, and 18 energetic third grade students picked up 3 pounds of trash from inside the fence that borders upper Moraga Creek.

On Saturday, September 17, Friends of Orinda Creek board members Jim Luini, Adriane Bosworth, Toris Jaeger, and Bob Stoops, supervised 42 terrific volunteers in downtown Orinda, San Pablo Creek. These volunteers, including girl scouts, boy scouts, parents, citizens, and high school students, spread out all along the creek from the back of the Chevron Station to the culvert under the Safeway parking lot; they cleaned up 48 pounds of trash from San Pablo Creek. Donna Pickthall, owner of Genuine Goodness (near the UPS store), kept everyone fueled with her delicious, made-from-scratch goodies that she donated to the cause.That is almost 90 pounds of trash that will NOT make its way to our coastal waters, thanks to these wonderful volunteers and their hard work. Thank you all for a successful multi-creek cleanup.
