Del Valle Regional Park is a part of the East Bay Regional Park District (EBRPD) in an unincorporated region of Alameda County, California, 10 miles (16 km) south of the city of Livermore.[1] The park covers 4,316 acres (~17.47 km2., ~6.74 sq. mi.).[1]

Geography

General Description

The park largely surrounds Lake Del Valle, an artificial reservoir made in 1968 by damming Arroyo Valle, a small river. The lake provides a source of recreation for visitors including swimming, fishing, and boating. There are lifeguards present at designated swimming areas.

The park also offers 28 miles (~45.1 km) of hiking, horseback, and bicycle trails, in addition to 150 camping sites. It is the eastern gate for the Ohlone Wilderness Trail, which leads to Sunol and Mission Peak Regional Parks.[1]

Trails

The park, like many East Bay Regional Parks, has numerous trails. One trail, the East Shore Trail, leads from the Arroyo Road staging area to a ridge above Del Valle, and then follows the lake for several miles toward the boat launch. The Sailor Camp Trail leads to the Ohlone Wilderness Trail, and an unnamed trail leads to Mendenhall Road. Most of the trails climb hills around the lake; most, however, stay between 500 to 1,500 feet (150 to 460 m) in elevation.[2]

Access to the park

By car

The park can be approached from Del Valle Park Road (via Mines Road) or Arroyo Road, where the parking meter is often broken. Del Valle Road connects to the southern end of the park, while Arroyo Road connects to the northern staging area.

Mines Road can be reached from Tesla Road (J2) and the California State Route 130. Arroyo Road can be reached from Concannon Boulevard and Wetmore Road.

By foot

You can reach the Arroyo staging area along a narrow footpath which connects to Sycamore Grove Park and the general LARPD (Livermore Area Recreation and Park District) trail network.[3]

History

Early Years

Construction crews began work on the lake in 1966.[4] The construction of Del Valle Reservoir was finished in 1968.[5] Del Valle Regional Park was opened to the public in 1970,[6] 36 years after the EBRPD was founded in 1934.[7]

California Drought in 2010s

In the mid-2010s, a severe drought struck the California region, including the East Bay.[8] This situation caused 12 million trees in California to die, and resulted in the East Bay Regional Park District writing an article to help with the drought.[9]

Flooding in the 2016-2017 winter

Shortly after the California drought in the 2010s, Del Valle Regional Park suffered widespread damage from the unusually heavy rains and La Niña that struck the East Bay in early 2017. Much of the damage was around Lake Del Valle, where runoff overflowed five times into beaches, campgrounds and picnic areas. Some of the trails were washed out and needed to be rebuilt. The park was closed for nearly three months, before reopening on April 15, 2017. EBRPD estimated the cost to repair this park alone at $1.8 billion, and said the cost would rise further if the rains continued.[10]

With another La Niña scheduled for the 2017-2018 winter, it is quite possible that repairs will have to be done after the upcoming winter as well.[11]
