2013 Update
Thank you to everyone who joined us for the Lake Merced Stakeholder Meeting on Wednesday, November 6, 2013. As requested, here is a link to the Lake Merced Presentation.  We are also providing direct links to the San Francisco Groundwater and Regional Groundwater web pages for more information.  

Lake Merced

Lake Merced is located in the southwest corner of San Francisco near Skyline and Lake Merced Boulevards.

Land Use
Lake Merced is an emergency source of water for the City of San Francisco to be used for fire fighting or sanitation purposes if no other sources of water are available. The San Francisco Recreation and Park Department manages the recreational areas of the Lake under a 1950 agreement with the San Francisco Public Utilities Commission. We manage the water aspects of the Lake. Lake Merced offers a variety of recreational opportunities to visitors:

  • Trails for walking, jogging, dog-walking, biking and bird watching
  • Fishing pier and boat launch
  • Harding Park and Jack Fleming Municipal Golf Course, a world-class 18 hole and executive 9 hole golf course

The purpose of this memorandum is to provide a summary of the 2010-2012 Lake Merced water quality data and determine if there has been a change in water quality at Lake Merced based on the representative water quality parameters. Read the memorandum.
