Lake Cunningham Park is an artificial lake in East San Jose, California, near the Eastridge Mall and Eastridge Transit Center. It is not a geological feature recognized in the Geographic Names Information System (GNIS). It is located on Capitol Expressway and stands next to Reid-Hillview Airport. The Lake Cunningham Skate Park and Raging Waters theme park are also in Lake Cunningham Park.
The Lake Cunningham – Eastridge Mall area was one of Santa Clara Valley's three permanent wetland complex called "lagunas". The area was called Laguna Secayre during the initial Euro-American settlement (1769–1850). Laguna Secayre covered a much larger area than Lake Cunningham Park does now.
The soil of the surrounding area is a heavy, dark clay; this indicates that the area was routinely flooded.
Due to intense urbanization in the surrounding hill areas, the storm water that historically exited the canyons and percolated through the gravel below ground was channeled into pipes below the streets to Thompson Creek and Lake Cunningham. This has led to an increase in runoff during the winter storms.
