About this marina
Big Break Marina sits on Big Break in Oakley, a flooded former island on the western Delta just off the San Joaquin River, next to Big Break Regional Shoreline. It's a popular launch for bass anglers heading into the western Delta.
For boaters
The state boating database lists about 300 parking spaces for vehicles with trailers, two boarding floats and dry storage for about 60 boats. There's a washdown area, fish cleaning station, store, haul-out and repair, and restrooms.
Before you go
Golden mussels are now in the Delta, so clean, drain and dry your boat before taking it to any inland lake.
