Quarry Lakes Regional Recreation Area is 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 Alameda County Water District acquired the quarry after the pumping was declared to be an illegal waste
in 1976.

The Park is located roughly between Centerville and Niles. It is bounded to the northeast by the train tracks of the BART system, and to the south and west by Alameda Creek.

History

As early as 1912, the Niles Sand and Gravel Company operated a gravel plant along the south bank of Alameda Creek in Niles, processing gravel and sand from the river bed for concrete production.[1] In 1954, the company expanded into the area now in the park, acquiring an operation previously managed by Black Point Aggregates.[2] By 1969, some of the gravel pits had been dug down to 120 feet below the surface, well below the water table. To continue extraction at this point, the company pumped the water flooding the pits out into adjacent Alameda Creek at a rate of five million gallons a day, enough to continuously supply 30,000 people.

In 1972, the Niles Sand and Gravel Company sued the

seawater intrusion from the San Francisco Bay and that the gravel pits would have flooded naturally even if the program were not in place, the court ruled against the company, declaring its pumping to be an illegal waste of groundwater.[3]

Due to the important role the lakes play in groundwater percolation, only Rainbow Lake and Horseshoe Lake are open to the public for water contact. These two lakes are stocked regularly with

water contamination.[5]

Lago Los Osos and Willow Slough are open to nature observation, but water contact is not allowed. Two additional unnamed lakes are closed entirely to the public for use by the ACWD.[4]
