Shadow Cliffs Park in Pleasanton to reopen

OAKLAND, Calif. (KGO) -- A park in the East Bay that's popular with swimmers will reopen Wednesday.

Shadow Cliffs Lake in Pleasanton had been closed since last week due to dangerous levels of E.coli. Hal MacLean with East Bay Regional Parks says it's a problem created in part by the drought, because the dead grass is no longer inviting for all the geese.

"The grass is brown," he said. "Right now we're not watering the lawns, so that's an area where the geese would normally congregate. Now the geese are congregating at the beaches. And so goose feces and low water quality is an issue."

New water tests found the levels have dropped significantly.

In the meantime, Oakland's Lake Temescal remains closed to swimmers due to a buildup of toxic blue-green algae in the water.
