Plan explanation

 

 The Kase River gives off the source in Mt. Sefuri system of Sanze-mura, Saga-shi, and the south drains the mountains while putting sacred water river, Tianhe river, supporting rivers such as excellent Ogawa together, and sect does the multi-Fuse River on the way and we further put Gion rivers together in the downstream and flow through Saga plains and are the first-grade river flowing into Ariake Sea.
 Because rain which fell because Sefuri mountain range of rear place was steep fell down river in addition to the downstream plains of the Kase River being low level ground of 0 meters above sea level at a stretch, flood damage often occurred.
 In addition, it was necessary to find stable water source to secure main industrial agriculture and city water of prefectural capital Saga urban area on Saga plains. From there being little flow rate of water source and river where it is with is Saga plains where a large quantity of water is required for agriculture of groundwater draw too much, and subsidence progresses in western district year by year, and farmland, river, road and other facilities suffer damage.
 As one of the countermeasures which overcame such a various problems, the Kase River dam was made.
