Geography edit
Puddingstone Dam serves mainly for flood control. It impounds Walnut Creek, a tributary of the San Gabriel River, to form Puddingstone Reservoir, which can hold more than 20,000 acre⋅ft (25,000,000 m3) of water.[1] The reservoir stores floodwater from both the Walnut Creek Wash, and also the San Dimas Wash, to which it is connected by a short artificial channel below San Dimas Dam.
