[2] The Stung Sen River Basin is the largest among the 11 main tributaries around Tonlé Sap with a catchment surface of 16,344 km2 (1,634,400 ha).

[1] The basin receives about 1,500 mm (59 in) of rain per year.

The northern extent of the river basin corresponds to the border with Thailand as in 1904, Siam and the French colonial authorities ruling Cambodia formed a joint commission to demarcate their mutual border to largely follow the watershed line of the Dângrêk mountain range.

Steung Saen (ស្ទឹងសែន) means "river of soldiers" in Khmer.
