For a good part of its initial course, the river flows in parallel with the Kollam - Shenkottai commercial highway. At Punalur, a Suspension Bridge was constructed across this by the Travancore Maharaja in British Style. This is still preserved as an archeological marvel. The end point of this river is the Ashtamudi Kayal. The river bed is usually rocky and it is difficult to swim and play in such as river. There are huge rocks, deep pits and other obstructions in the river. In modern times, the Thenmala dam is built on this river. This is an irrigation dam mainly aimed at providing water to the downstream regions throughout the year.
