Brannan Island State Recreation Area - Site # 5054
Brannan Island State Recreation Area is a maze of waterways through the Sacramento-San Joaquin Delta. This park northeast of San Francisco Bay, has countless islands and marshes with many wildlife habitats and many opportunities for recreation, including boating and swimming.

One of the outstanding water-oriented recreation areas in the world, the area offers great fishing, including striped bass, sturgeon, catfish, bluegill, perch and bullhead. Franks Tract, a protected wetland marsh, is home to beaver, muskrat, river otter, mink and 76 species of birds.
RegionalRegional - worth visiting if you are already in the area. They may be located farther from populated areas or with more limited wildlife species.

Background: In 1921, on the southern tip of Brannan Island, was a swampy area of approximately 335 acres. The property was part of the Peter Cook holdings. The land was acquired by the Sacramento San Joaquin Drainage District for the State Reclamation Board for use by the United States Army Corps of Engineers. The area, was pumped full of sand and silt from the river during the dredging and widening of the Sacramento River channel between 1926 and 1929. The dredging operation filled the area with spoils to a level between twenty to forty feet above water level. After the operations were over the land sat idle, except for sales of sand by the State to private contractors.

In 1950 the Rio Vista Chamber of Commerce spearheaded a drive to have the area become a State Park. A transfer of the title to the property to the State Division of Beaches and Parks, set the stage for the creation of the park. Between 1952 and 1954, the area again sat idle. The Division of Beaches and Parks granted permission to Travis Air Force Base to establish a boat harbor on Seven Mile Slough for Air Force Personnel.

Over the years improvements and additions to park facilities have made Brannan Island State Recreation Area an important recreational facility strategically located between the Sacramento and San Joaquin Rivers. The dredging that created the area for the park also made it the highest spot east of the Sacramento River for a radius of 10 to 25 miles.
Identification of the Delta’s prehistoric residents is challenging. Archaeologists speculate that agricultural activity, dredging, levee construction and reclamation efforts may have altered the locations of—or even destroyed—any identifiable Native American artifacts.

The Habitat: The area offers fishing, including striped bass, sturgeon, catfish, bluegill, perch and bullhead. Southeast, accessed by the San Joaquin River, Frank’s Tract, a protected wetland marsh, is home to beaver, muskrat, river otter, mink and 76 species of birds.

The Experience: The climate in the Delta is mild, with winter temperatures usually ranging between 45 and 55 degrees and summer temperatures between 75 and 95. An occasional heat wave will push the temperatures in summer to 100 degrees or more but the Delta breeze is never far away.

Viewing Tips: The area offers fishing, including striped bass, sturgeon, catfish, bluegill, perch and bullhead. Southeast, accessed by the San Joaquin River, Frank’s Tract, a protected wetland marsh, is home to beaver, muskrat, river otter, mink and 76 species of birds.
• A diversity of birds—including Swainson’s hawks and sandhill cranes—overwinter and migrate or breed in the Delta.
• In marshes, herons, river otters and turtles live among tules, sedges and cattails.
• Riparian scrub supports several dozen bird species. Various fish and mammals live among willows and cottonwoods.
• The riparian habitat hosts many species of rare plants—such as Mason’s lilaeopsis and Suisun marsh aster—at or below the
high tide zone.
