Details Toyogawa Canal project was implemented for the purpose of securing irrigation water, domestic water and industrial water for the East Mikawa Region of Aichi Prefecture and Kosai Region of Shizuoka Prefecture. To promote the purpose, the inter-basin water transfer scheme from Tenryu River system to Toyo River system was implemented. With the combined use of Ure Dam, Ono Head Works, main and lateral canals, and regulating ponds, etc., management operations of this canal project has been carried out smoothly since the operations start in April 1968. Toyogawa Comprehensive Canal, which in parallel with the original Toyogawa Canal, uses Oshima Dam as its water source facility, Kansagawa Canal facility and 4 regulating ponds in its territory have been managed for the supply of irrigation water and urban water for the said region since April 2002. After that, Toyogawa Canal Stage II project started to implement dual canals on the main canal for stable water conveyance, proper maintenance management, and efficient water utilization.
