Castro Creek is a small waterway located in Richmond, California. It flows through the western part of the city. The creek is very close to the Chevron Oil Refinery. Another nearby creek, Wildcat Creek, also flows into it. Eventually, the water from Castro Creek and its connected areas reaches San Pablo Bay. Long ago, this creek was part of a channel. This channel helped separate the area known as Point Richmond from the mainland.
How Castro Creek Got Its Name

This waterway is named after Don Víctor Castro. He was a very important person in the area a long time ago. Don Víctor Castro owned the land where the creek flows. This land was part of his large ranch called Rancho San Pablo.
Why Castro Creek is Important
Castro Creek is a special place for nature. Many people enjoy fishing and shell-fishing here. It is also a great spot for other outdoor activities. The creek's habitat is very important for several types of animals. Some of these animals are even endangered, meaning they are at risk of disappearing. The creek is also a key area where fish lay their eggs and where young fish grow. It is also a pathway for fish moving between different water bodies.
The Chevron Richmond Refinery is located near the creek. This refinery uses a lot of water in its operations. This water, which includes cooling water and rainwater, is released into Castro Creek. It also flows into nearby Castro Cove, Wildcat Marsh, and San Pablo Bay.
Protecting Castro Creek
Over many years, some parts of Castro Cove became polluted. This was due to past releases from the refinery. The pollution included substances like PAHs and mercury. Because of this, efforts began in 2007 to clean up Castro Cove. These cleanup projects help to make the creek and its surrounding areas healthier for wildlife and people. Protecting places like Castro Creek helps keep our environment safe and clean for everyone.
