前回、2021年のプロジェクトで七倉ダムの下端広場の地面に表示した風向曲線に直径100mのコンパスを上書きし、高瀬川の川筋を臨んで方位NNW（北北西）22.5°を表示、七倉ダムの下端から高瀬川の源流をたどるとともに、七倉ダム以降のSW（南東）に向かう流路も想定し表示する。また、先述の調査の過程と結果を複数枚のデジタルサイネージにより七倉ダムの下端広場に展示する。

高瀬川は水俣川を源流として高西調整池を発し、東方向に流れ高瀬ダムに至る。松本盆地を形成している高瀬ダム、七倉ダムは、西向きに流路を変えて流下し、七倉ダムに至る。以後、西に流路を変え、高瀬川総合発電所付近で鹿島川、篭川、農具川に注ぎ、松本盆地に至って犀川と合流して千曲川となり、新潟県境（津南町）で信濃川と名を変えて妻有台地を開削し、中津川、清津川の流れを集めて北上し新潟市で日本海に注いでいる。

North by North West, 2024

In the 2021 project, a 100-meter diameter compass was superimposed on the wind direction curve displayed on the ground at the lower plaza of Nanakura Dam. It marked the direction NNW (North-Northwest) at 22.5 degrees, facing the course of the Takase River, tracing its source from below Nanakura Dam and also outlining the river’s subsequent flow toward the southeast (SE). Additionally, the process and results of the aforementioned survey were displayed on several digital signs at the lower plaza of Nanakura Dam.

The Takase River originates from the Minamata River and flows east from the Takase Regulation Pond to the Takase Dam, forming the Matsumoto Basin. The Takase and Nanakura Dams redirect the river westward, flowing down to Nanakura Dam.

Subsequently, the river changes course to the west, merging with the Kashima River, Kago River, and Nougu River near the Takase River Comprehensive Power Station, then joins the Sai River in the Matsumoto Basin to become the Chikuma River. It changes its name to the Shinano River at the Niigata Prefecture border (Tsugawa Town), carving through the Echigo Plateau, collecting the flows of the Nakatsu and Kiyotsu Rivers, and eventually discharging into the Sea of Japan at Niigata City.
