100th Anniversary of the Necklace of Lights (1925-2025)
Welcome to LakeMerritt.org
Lake Merritt in Oakland, California is one of the most unique urban spaces in the United States. Its three mile Necklace of Lights shoreline in the center of an exceptionally diverse city is a special place where nature and nurture migrate and mingle daily. This tidal lagoon is home to the United States' oldest designated wildlife refuge dating from 1870. lakemerritt.org is an independent, ad-free resource site with current information about Lake Merritt and links to the volunteer groups and advocacy agencies working for the common good of the lake and the lake area community. Its focus is promoting stewardship of the lake.

ALGAE...
grows in large quantities during the spring and early summer, but only in the shoreline area where depths are four feet or less. Although a very beneficial part of the food chain, it becomes a nuisance when there is too much of it, causing odors and depleting oxygen levels when it decays. Algae is kept in check by removal with the harvester boat. .... several types of algae grow vigorously in the shallow waters. Most common are light green filaments of Cladophora and Enteromorpha, along with the darker green sea lettuce (Ulva). This growth is limited to 20 - 25 feet of the shoreline where the water is only zero to four feet deep. At greater depths, light penetration is not sufficient for growth. By mid-May, algae may cover the entire shoreline area out to deeper water, blanketing the area in bright green where only murkywater existed just a month before. Towers of algae billow up, providing both shelter and food for both fish and invertebrates...."
