Quarry Lakes Regional Recreation Area in Fremont is jointly administered by the East Bay Regional Park District (EBRPD) and the Alameda County Water District. EBRPD operates the park as a recreational facility featuring water-related activities such as swimming, fishing, wind surfing, and boating. ACWD uses the lakes for recharging the aquifers of the Niles Cone Groundwater Basin, an immense, natural reservoir lying beneath the Tri-City area. This is accomplished by:
The Niles Cone supplies up to half of the water used in Fremont, Newark, and Union City.
Find out more about the recreational opportunities available at Quarry Lakes by visiting the EBRPD website.

To protect wildlife and water quality, lead fishing tackle is prohibited at Quarry Lakes. The Quarry Lakes Lead Fishing Tackle Awareness and Exchange Program was created to educate local anglers on the hazards of using lead fishing tackle and to provide the opportunity for a no-cost exchange of toxic lead split-shot weights and sinkers for lead-free split-shot weights and sinkers.
