(TM1) Tokyo Metropolitan Waterworks Map 東京都水道地図 and Murayama-shimo dam 村山下ダム

Tama Lake 多摩湖 (aka Murayama Reservoir) sits at the edge of Tokyo, next to Sayama Lake 狭山湖 in neighboring Saitama. (And apparently is the homeland of Totoro). Here’s a map that includes both of the lakes:

Photo 2: 多摩川の原水の流れ図 (Flow chart of untreated water (gensui) in the Tamagawa River)

Among the many parks in this area is Sayama Park Upper embankment square 狭山公園堤防上広場, at the top of the southern corner of the Murayama-shimo dam 村山下ダム (map). Here’s a photo from the park:

Just downhill from this spot is an old spillway.
