Close to the famous tourist attraction of the province, Huai Mae Khamin Waterfall is located in part of the Srinakarin Dam National Park. This area was created by the construction of the Srinakarin Dam, which blocks the flow of the Mae Klong River (the main tributary). Several important rivers and streams flow into this reservoir, including Huai Mae Khamin, Huai Kha Khaeng, Huai Mae Wong, Huai Krieng Krai, and Huai Mae Plu, among others. Additionally, there are many other streams that flow into the Kwai Noi River in the area of Sai Yok District.
