Nambe Falls is located East of Pojoaque, directly North from Santa Fe. During the spring, the lake fills and the water pours over the top of the spillway.
By October, the Spring snow melt water is all gone, the flow is minimal and the water supply must be preserved. Thus, the unimpressive flow. By the way, though the dam and falls are spelled with an 'a,' the name of the reservoir is Nombe.
