[5] Del Valle Regional Park was opened to the public in 1970,[6] 36 years after the EBRPD was founded in 1934.
[9] 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.
