The valley of the Pa Sak through the Phetchabun mountains is the main part of Phetchabun Province. As the watershed of the river is rather narrow, the amount of water in the river changes a lot seasonally. To level the drought problems in the lower Pa Sak valley, in 1994 the construction of the Pa Sak Joalsid Dam (เขื่อนป่าสักชลสิทธิ์) in the Lopburi Province was started. The 4,860 meters wide and 31.5 m high dam keeps a total of 0.785 km³ of water. Additionally to the water management the dam also supplies about 6.7 MW of hydro-electric power.
