Padsan River
The Padsan River, sometimes referred to as the Laoag River or the Sarrat River in Ilocos Norte is a body of water which is notable because its main channel bisects the central townships of the Municipalities of Dingras and Sarrat, as well as that of the Component City of Laoag, which is the capital of Ilocos Norte. As a result, its waters have shaped the history and culture of these historic towns, and of the province of Ilocos Norte. It is the site of the Madongan Dam in Dingras, and is right beside the Laoag International Airport in Laoag.
