Mission Bay (San Diego)
bay in San Diego County, California, United States
Mission Bay is an artificial, saltwater bay located south of the Pacific Beach community of San Diego, California, created from approximately 2,000 acres (810 ha) of historical wetland, marsh, and saltwater bay habitat. The bay is part of the recreational Mission Bay Park, the largest man-made aquatic park in the United States, consisting of 4,235 acres (17.14 km2), approximately 46% land and 54% water. The combined area makes Mission Bay Park the ninth largest municipally owned park in the United States.
The bay was created to enhance recreational opportunities in San Diego. Wakeboarding, jet skiing, sailing, camping, cycling, jogging, roller skating, skateboarding, and sunbathing are all popular around the bay. Mission Bay Yacht Club, on the west side of the bay, conducts sailing races year-round in the bay and the nearby Pacific Ocean and has produced national sailing champions in many classes. Also on the west side of Mission Bay lies Mission Bay Sportcenter, which offers boat rentals in Mission Bay and boasts the largest aquatic Youth Camp in San Diego.
Fiesta Island, a large peninsular park located within Mission Bay, has a large off-leash dog park and is a popular location for charity walks and runs, bicycle races, time trials, and other special events like an over-the-line tournament. It is also home to an impressive diversity of rare, threatened, and endangered bird and plant species, despite the popularity of the area for people and dogs. Mission Bay is also host to the annual San Diego Bayfair Cup, a hydroplane boat race that takes place on the H1 Unlimited circuit.

Why this record matters

Place names and jurisdictional language are key evidence: both can reveal earlier catalogue descriptions and overlooked record series. The source revision retrieved here is dated Jun 3, 2026. The linked authority identifier is Q3316725. The Library of Congress control number is sh2002007355. Authority coordinates are 32.779, -117.234. 2 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.
Modern boundaries and familiar names can conceal earlier jurisdictions or structures that do not align with the present site. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
