桜丘宇山遊水池 _ Sakuragaoka Uzan flood control basin Traditional Cache

Here there is a small park. I hid the cache near this. Please bring your pen.

Depression facing the hill of Musashino Plateau has become a flood control basin, south waterway has become one of the headwaters Yazawa River. Waterway spans become a culvert Setagaya Street, Yazawa River has continued to Todoroki Valley.

武蔵野台地の高台に面した窪地は遊水池になっており、南側水路は谷沢川源流の一つになっています。水路は世田谷通りを暗渠となって渡り、谷沢川は等々力渓谷へと続いています。
