Hamura Intake Weir(Hamura Weir)
river running between Tokyo-to and Kanagawa Prefecturesluice gatewater trickling from the Tamagawa River
It is an intake weir for the Tama River that was constructed at the same time as the Tamagawa Josui, and was completed in 1653. It consists of a tidal weir that holds back the river, a fixed weir, a fish passage for fish to come and go, and the first sluice gate that takes in the water that has been held back. When the water level of the Tama River rises above a certain level due to heavy rains such as typhoons, the weir is removed and the weir itself is flushed downstream, and when the water level drops, the weir is rebuilt. When the water level drops, the weir is reconstructed. Raw water taken from the reservoirs is led to the Murayama-Yamaguchi Reservoir and the Ozaku Water Filtration Plant, as well as to the Higashimurayama Water Filtration Plant via the Tamagawa Josui Channel. Nearby stands a statue of the Tamagawa brothers, who made great contributions to the construction of Tamagawa Josui.
