The Yolo Bypass at a Crossroads: Flood Protection, Habitat, and the Future of a Working Landscape
Sabrina Snyder, Yolo County
The Yolo Bypass is one of California’s most remarkable working landscapes, supporting flood protection, agriculture, wetlands, and critical wildlife habitat. Today, an unprecedented convergence of major water infrastructure and ecosystem restoration initiatives is poised to reshape how this landscape functions. This talk will look at the projects driving these changes, why the Yolo Bypass has become a focal point for regional flood management, water supply, and habitat restoration, and what these investments could mean for its future.
Sabrina Snyder is a Senior Management Analyst for Yolo County, where she manages the County’s Water Resources Program. Snyder provides recommendations, implements water policy, and engages the public on the many Federal, State, and Local water and natural resource planning initiatives in the Yolo Bypass and greater Sacramento San Joaquin Delta region.

Mike Davis – Yolo Basin Foundation Volunteer
March 6, 2025
If a spectacle refers to a public display of something that is dramatically eye-catching, then ...there are wildlife spectacles in the Yolo Bypass Wildlife Area that meet that definition. One of the most popular spectacles is the nightly exodus of great clouds of bats that leave their roost under the causeway to catch insects. The quarter of a million bats in the Wildlife Area is one of the largest bat colonies in the state. The return of King salmon to Putah Creek, which transverses the Wildlife Area, is a major celebratory event for our area. Runs of spawning salmon are one of the greatest wildlife spectacles on earth. Other spectacles include soaring white pelicans, hypnotic murmurations of blackbirds, expansive stands of the amazingly complex wildflower Downingia, and large flocks of snow geese flying in V formation, the very definition of a spectacle. But there are other spectacles that might surprise you. Join the meeting to learn more!
Mike Davis is a retired Professor and Cooperative Extension Specialist in the Department of Plant Pathology at UC Davis, where he taught plant pathology classes as well as courses on mushroom identification and cultivation.

Megan Isadore – River Otter Ecology Project
February 6, 2025
Join Megan Isadore for an entertaining and educational program to learn ...about river otters’ remarkable lives and adaptability. River Otter Ecology Project has been studying the resurgence of otters in the Bay Area and beyond since 2012. Learn about their life history, prey species, behavior, and why we care so much about where they live and how they are doing.
Megan Isadore graduated from the College of William & Mary with a degree in English. She began as a medical writer, and turned her attention to watershed ecology while working with the critically endangered coho salmon of Lagunitas Creek, which led to an interest in watershed ecology. River otters, as the flagship species for conservation, are a natural fit. Their charm, playfulness, and their remarkable ability to touch hearts are among the many attributes that make them ideal ambassadors for watershed conservation and wetland restoration.
Calling all Otter Spotters! Input your sightings at http://www.riverotterecology.org, check out the maps and information. http://www.riverotterecology.org. If you’d like to keep up with river otters, sign up for their email list from the home page. Thanks for joining us!Show More
