Pine Lake, previously known as Laguna Puerca or Pig Lake, is a freshwater lake in Pine Lake Park in the southwest corner of San Francisco. The lake is fed from the same aquifer as nearby Lake Merced. [2]
The surrounding area and lake, then known as Laguna Puerca or Pig Lake, were purchased by the Greene family following their move from Maine to San Francisco in 1847. [3] The lake was purchased by the City of San Francisco in the five years following the nearby Sigmund Stern Recreation Grove. [3]
The lake is fed by an underground spring, which also feeds nearby Lake Merced. [3] It is surrounded by willows, tules, and aquatic plants. [3] Migratory birds along the Pacific Flyway stop to feed, rest, or inhabit the surrounding area. [3] The only natural freshwater lakes in San Francisco are Pine Lake, Lake Merced, and Mountain Lake.
