Lake Merritt, located in the heart of Oakland, California, is the pride of the city. An estuary connected to San Francisco Bay, mixing sea and fresh waters, the lake formed about 4,000 years ago when the sea level rose to fill the mouths of two streams as glaciers collapsed worldwide. For at least the past 3,500 years, the Ohlone people lived by the estuary and its mud flats, building mounds nearby, Lake Merritt, known by other names prior to 1869, served as a waste dump until Samuel Merritt dammed the channel to the lake, thus preventing high-tide water from leaving the lake at low tide. As Oakland grew from a small town, the lake attracted the attention of well-to-do citizen of Oakland, who built mansions around it. In 1870, California designated it as a wildlife refuge, the first in America, protecting all organisms in and around the lake. Growing in importance to the residents of Oakland, the lake has undergone modifications to integrate it into the city as the welcoming and enjoyable place it is today. Jere H. Lipps has studied the animals and plants of Lake Merritt as a marine biologist and geologist.

A professor at the University of California, Berkeley, Lipps has received various awards, including the United States Antarctic Medal (1979). He has taught thousands of students in oceanography, geology, paleobiology, and field courses. The Images of America series celebrates the history of neighborhoods, towns, and cities across the country. Using archival photographs, each title presents the distinctive stories from the past that shape the character of the community today. Arcadia is proud to play a part in the preservation of local heritage, making history available to all.
