Quarry Lakes Re-Opens for Swimming: Saturday, June, 25


Grab your beach towel and sunscreen - Quarry Lakes re-opens this weekend for swimming! 

The East Bay Regional Park District announced Friday that the popular swim facility in Fremont will re-open on Saturday, June 25, after it closed in early March due to toxic algae. 

The Alameda County Environmental Health Department cleared the lake to re-open late Wednesday after tests showed little or no toxins for at least a month. The highest result during the past month was 1.3 parts per billion, well below the state’s maximum safety threshold of 6 parts per billion. 

Park District tests have shown the lake has had little or no toxins for at least a month. 

Dogs are still not permitted to swim in the lake, but the lake continues to be safe for fishing. 

Quarry Lakes is open for swimming from 11 a.m. to 6 p.m. Lifeguards are on duty. Fees are $3 for visitors ages 16 to 61, $2 ages 1 to 15 and seniors over age 62. Parking is $5. Quarry Lakes Regional Recreation Area is located at 2100 Isherwood Way, Fremont. 

All of the Park District’s other lakes are also open for swimming but Park District staff are advising dog owners to keep their pets out of the water due to low level toxins.
