There are Shiba river and Kamo river as the first-grade river belongs the Ara river water system and they flow with sandwiching Takasaki Line.
It assumes that the source of Kamo river is the neighborhood of 1-chome Kamogawa Okegawa city and the river goes toward the south to being substantially in parallel with Takasaki Line. Then the river gathers many branches in Ageo city and gradually increases with flow quantity and goes to south in the western part of Saitama city. And the river flows into Ara river at Uchimagi Asaka city. Kamo river extends for 19.2km.
I installed the cache at the open conduit part apart several hundred meters away from the source of Kamo river.
高崎線を挟むように流れる荒川水系の一級河川として芝川と鴨川があります。
鴨川は桶川市鴨川1丁目付近を源流とし、ここから高崎線に略平行に南下し、上尾市で幾つもの支流を合わせ次第に流量を増し、さいたま市の西部を南下し、朝霞市内間木で荒川に合流する延長19.2kmの河川です。
鴨川の源流から数百ｍ離れた開渠部分にキャッシュを設置しました。
