The river is joined by a small stream from the south at a small village, 2. 2 km east of the NH 17 road bridge, while the river is joined from the south by the Pambar River at Koottar. The western part of the Manjampatti Valley catchment basin drains into the end of the Chinnar River. This Valley is drained by the stream Ten Ar and a smaller unnamed stream 2 km to its west. The unnamed stream is the N-S political boundary between Tamil Nadu and Kerala. The top of the ridge above this stream to the west is the western limit of the catchment. This unnamed stream joins the Pambar River at the point they both join the Chinnar River at the north west corner of the Valley.
