4K 奥秩父もみじ湖を散歩〔秩父/埼玉〕/ 4K I took a walk around Lake Okuchichibu Momiji (Japanese Dam lake).
埼玉県秩父市にある奥秩父もみじ湖（滝沢ダム）を散歩したよ。
平成23年に完成した多目的貯水池で高さ123ｍの重力式コンクリ－トダムだよ。
ダム直下にある雷電廿六木橋（らいでんとどろきばし）は大きなループ橋で珍しいね。
I took a walk around Okuchichibu Momiji Lake (Takizawa Dam) in Chichibu City, Saitama Prefecture.
It is a gravity concrete dam with a height of 123m and is a multipurpose reservoir completed in 2011.
Raiden Toroki Bridge, located directly below the dam, is a large loop bridge that is unusual.
