Quarry Lakes Regional Park

Quarry Lakes Regional Recreation Area is a regional park located in Fremont, California that is part of the East Bay Regional Parks system. Before being converted into a park, the site was used as a gravel quarry. When water purchased by the public for groundwater recharge of the Niles Cone flooded the gravel pits, the gravel harvesters began to daily pump the seeping water down Alameda Creek into San Francisco Bay.

The Niles Cone is a groundwater basin in Alameda County, California, United States which is the source of drinking water for a sizeable human urban population in the East Bay. The land area corresponding to this groundwater basin is approximately 103 square miles; (California, 1998) the Niles Cone Basin is bounded on the east by the Diablo Range and on the west by San Francisco Bay.
