Geography

It then flows through the Wang Thong District where it is referred to as the Tha Muen Ram River (Thai: แควน้ำท่าหมื่นราม), then flows through the Bang Krathum District, and through Wat Ta Yom, where it is referred to as the Wat Ta Yom River. It discharges into the Nan River in Phichit via the Tha Luang Canal (Thai: คลองท่าหลวง) at 16.44083°N, 100.35583°W.
