Lake Cunningham - former gravel quarry turned urban reservoir

Lake Cunningham Regional Park contains a large artificial lake that occupies a former gravel-mining pit and serves as a stormwater retention basin and recreational feature. The lake and surrounding park are anomalous in the urban fabric of San Jose because they occupy a deep, human-made depression collecting runoff from surrounding hills. The site now hosts recreational facilities including trails, a skate park, and proximity to Raging Waters amusement park, illustrating adaptive reuse of an industrial excavation within city limits.
