Spawning Season Continues in Lagunitas Creek

Coho salmon spawning ramped up considerably in Lagunitas Creek at the end of December. Biologists with Marin Water and the Watershed Stewards Program observed 87 coho salmon and 45 coho salmon redds (gravel nests) spread throughout the creek. So far we’ve observed 144 coho salmon and 57 redds, which is already close to last year’s total. Unlike last year, quite a few salmon have been spawning at the Leo T. Cronin fish viewing area, which is the easiest place for the public to see them.
With additional rain we should see more salmon migrating and spawning through the end of the year and into January. If you go out to see the salmon, please remember to stay socially distanced. The fish viewing area is likely to be crowded and isn’t the only place to see fish. Salmon are spawning throughout Samuel P. Taylor State Park and the Cross Marin Trail offers many places to catch glimpses of them. They tend to build their redds in areas where slow water transitions to fast, turbulent water. Look for pink and red flags along the banks, which mark the locations of recent redds. If you know where the Swimming Hole is, we recently saw a school of a dozen Coho in there.

How to Stay Safe While Visiting the Watershed

Our Mt. Tamalpais watershed typically sees more than 2 million visitors annually. And since the pandemic started in the spring, we have seen a large increase in visitors using our watershed trails, roads and relaxing alongside our reservoirs.

These are stressful times, and the Mt. Tam watershed is a precious community resource. The watershed is open to all visitors, for hiking, biking, and horseback riding. Visit this page for more information about recreation activities on the watershed.

Please be respectful and share the roads and trails. We ask that all our visitors maintain at least 6 feet of physical distancing, and please wear a mask if you cannot maintain that distance. If you are not feeling well, or if you have a fever, please do not visit the watershed until you are feeling better. 

Let’s work together to create a safe and enjoyable experience for everyone.

Marin Water is installing a new pipeline under a portion of Sir Francis Drake Boulevard in Kentfield, replacing old pipes that date back to 1920.

The new pipeline, which also has features that will improve its seismic reliability, is part of our ongoing work to upgrade aging infrastructure and improve the overall reliability of our system. The cost of the project is $3.9 million, and the majority of the work will occur at night to minimize traffic disruptions. Drivers in the area can expect partial lane closures and some traffic delays.

Construction is being done in tandem with Marin County’s Sir Francis Drake Boulevard Rehabilitation Project, “Upgrade the Drake,” to reduce costs and minimize disruptions. Construction began in June and continues through June of 2022. To learn more, call 415.688.7613 or visit
