Xabatin: Big Lake Big Science Director’s Cut
Documentary Provides Scientific and Historical Narrative on Clear Lake and Its Watersheds
Xabatin explores research at Clear Lake, California’s largest natural freshwater lake. It highlights the region's beauty and wildlife, blending science with collaborations among Native American Tribes, government agencies, and non-profits."

During the October 7, 2025, Board meeting, Chief Deputy County Administrative Officer Matthew Rothstein recognized Angela DePalma-Dow and Samuel Euston for their dedication and contributions to the documentary.

The documentary premiered the director’s cut on September 12, 2025, at the Soper Reese Theatre. Rothstein shared that the documentary “has generated a positive response and truly celebrates Lake County’s central feature, Clear Lake. From the outset, the intent has been to segment the film for educational use and to present the full-length documentary at film festivals into 2026.”
District 2 Board Supervisor Bruno Sabatier shared, “the County contributed to the initial funding and recognizes the hard work involved.”
The documentary thanks its primary sponsors:
Karen and Samuel Euston
Angela DePalma-Dow
The County of Lake
Lake County Watershed Protection District
Lake County Land Trust

Public comments reinforced the documentary’s value:
“The Board’s initial support of the documentary was helpful in getting it started. The documentary extends the positive effects of the Clear Lake Integrated Science Symposium (CLISS) which the Board supported. CLISS and Xabatin are placing Lake County on the scientific, cultural, and conservation stage. It provides valuable resources for classrooms and inspires young citizen scientists. Screening the documentary in additional venues extends its message and showcases Lake County as a community that celebrates science, culture, and conservation.”
The documentary segments were also designed for release as primary and secondary education resources.
