Bull Island is an island in the Napa River, in Napa County, California. From the 1880s onward, it was owned by the Money family, who constructed levees and reclaimed the land, using it to farm grain and potatoes. It was described as a "fine ranch" in 1918. After a levee failure in 1954, it gradually eroded into the water, becoming a salt marsh; for some time afterward, it was used as an evaporation pond for the industrial production of salt by the Leslie Salt Company. Beginning in the 1970s, Bull Island was proposed for inclusion in a variety of riparian preservation projects, but none came to fruition. However, in 1997, the Money family sold it to the California State Lands Commission, who turned it into a wildlife habitat; today it is administered as part of the Fagan Marsh Ecological Reserve, and hosts animals of numerous endangered species.
Russ Island is a mostly-submerged island in the Napa River, in Napa and Solano Counties, California.

The company allowed parts of it to be used for duck hunting. By the 1990s, it was acquired by the California Department of Fish and Game, who turned it into a wildlife preserve, and allowed it to return to marshland; it is now managed as part of the Napa-Sonoma Marshes Wildlife Area, and is open to hunting, fishing, birdwatching, photography and hiking activities.
