The Dutra Museum of Dredging

Dutra Museum Old

The collection, unique in its scope and size, spans the century that has elapsed since the introduction of steam-powered dredging equipment to the California Delta.


Museum of Dredging

The Dutra

What to See

The collection is housed in a craftsman- style mansion built in 1907 and located in Rio Vista, California. Originally built for local farmer John McCormack, the Dutra family became the home’s fourth owner when Ed and Linda Dutra purchased it in 1978. They used the home as their private residence, company office for Dutra Dredging and museum. It is currently owned by the Dutra Museum Foundation. The museum houses many photographs, log books, ledgers, dredge models, original engineering drawings on linen, a mammoth bone extracted from a Delta island, and a mural that depicts the Dutra family’s Portuguese whaling heritage. Noted Delta artist and family friend, Marty Stanley painted the mural.

Our Mission

The Dutra Museum is dedicated to promoting an understanding of the history of dredging, the value of developing and reclaiming the California Delta, and the significant role The Dutra Group and Dutra family have played in this field. Our purpose is to raise and manage funds to expand, preserve, exhibit and interpret the museum’s collection for public use and scholarly research. The Dutra Museum Foundation’s commitment to the community includes annual funding of higher education scholarships for, among others, Rio Vista High School and the Portuguese Historical and Cultural Society.
