Shadow Cliffs Arroyo Water Quality Conditions

  • There are no current advisories for blue-green algae posted at Shadow Cliffs Arroyo. See the Blue-Green Algae Information page for additional details.

A haven for swimming and fishing can be found at Shadow Cliffs, only a mile from downtown Pleasanton on Stanley Boulevard.

Shadow Cliffs, formerly a gravel quarry, was donated to the Park District by Kaiser Industries and opened as a park in 1971. Its assessed value of $250,000 was used to obtain a matching grant for development of the park from the U.S. Bureau of Outdoor Recreation.

With this start, the Park District has developed a 266-acre park including an 80-acre lake and ample parking and picnic grounds. There are facilities for persons with disabilities.

Besides the main lake, Shadow Cliffs has an arroyo with a chain of smaller lakes and ponds. Check signage for latest water quality conditions. No swimming or boating is allowed here; the shady areas and quiet waters make for a peaceful retreat on hot summer days. 

In 2017, solar panels were installed at Shadow Cliffs. The project includes solar panels that generate 1.2 megawatts of energy annually – enough to offset electricity use for almost the entire Park District – along with three electric-car charging stations, a recycled water line, and planting of native trees. This solar carport system also provides much-needed shade for the parking lots at Shadow Cliffs.

To Reach The Park

Park Accessibility

Shadow Cliffs offers wheelchair accessible parking, trails, picnic tables and restrooms. A wheelchair accessible fishing pier is located near the boat launch and can be reached by paved trail. The bathhouse is also accessible to wheelchair users. 

Beach wheelchairs, intended to provide a means for wheelchair users to travel across the beach, are available for free, on a first-come, first-served basis. They require an assistant to push and are not intended to enter the water. To arrange for use of a chair, call the Shadow Cliffs lifeguards at (925) 484-1986. A staff member will bring the chair out to the beach. It takes approximately 15 minutes to prepare the chair. Staff will give a brief orientation to the chair and arrange a time for the chair to be returned.

The interpretive pavilion has a paved ramp that leads to a shaded area and has adjacent accessible parking spaces for visitors to enjoy.

The Lake Trail is a level, paved path with minimal incline and can be accessed via the first parking lot after entering through the kiosk station or from the marina area.
