The river passes through Preah Vihear Province and Kampong Thom Province. 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.
