The Toyohira river flows through the city of Sapporo. The river is so wandering that it often flooded after the heavy rain at the Meiji era. The Hokkaido Development Commission decided to repaire the Toyohira river to a straight line. After World War II, the population of Sapporo increased quickly, so that it became under a shortage of water and power supply. More, there were still some floods as usual after the heavy rain or the water of melted snow in the beginning of spring. The Hokkaido Development Bureau made a plan to build a dam to prevent danger of flood and to supply more electric power. As a result, The Houkeikyo dam had been built here from 1965 to 1972. It was the year of Sapporo Winter Olympic Game. At that time, the population of Sapporo was one million(now, 1.92million) and the Hokeikyo dam has been a important origin of supply for water and power.

After that, the population of Sapporo went to increase, so that another dam was built at the opposite side over the town of Jozankei, which is called the Jozankei dam. These two dams support the life of Sapporo.
