Envelope reads, "Lake Merritt." Negative shows a portion of Lake Merritt with several sail boats. Only one or two buildings visible on the shore in the background. Betsy Willcuts, May 2002 Bibliography: THE HEART OF OAKLAND, A Walking Guide to Lake Merritt by Leslie Flint, Sponsored by the Camron-Stanford House Preservation Association Lake Merritt was a tidal slough; part of an estuary flowing into San Francisco Bay. At low tide it was a swampy, smelly marsh, and at high tide, it was a lake much as you see it today. At the time Oakland was incorporated in 1852, the outlet from the lake to the bay was considerably larger than what you see today, stretching almost the entire length of the present day viaduct. The only access to the towns on the eastern shore was by boat across San Antonio Slough or around the lake by a long route through the hills. In 1853, Horace Carpentier built a toll bridge at 12th Street. In 1869 Dr. Samuel Merritt, then Oakland's mayor, funded the construction of a dam at the 12th Street Bridge. Lake Peralta became known as Lake Merritt. Under Mayor Mott (1905-1915) Lake Merritt was made into a park with a boulevard around the lake, a municipal boat house, a bandstand, and hiking trails. During that time the City Hall, the Oakland Auditorium (Henry J. Kaiser Convention Center), and the Oakland Public Museum (Camron-Stanford House) were built. Note: In 1969, the Oakland Museum, now the Oakland Museum of California opened.
