Cabaruan is a newly created barrio, only after the great flood of 1939. Before this date it was just a part of the barrio of Turayong. Cabaruan is derived from Ilocano word “BARU” meaning new. It is almost an area of two hundred hectares mostly level land.  It is less than a kilometers away from the Municipal building of the town of Cauayan. This barrio, lies along the provincial road of Ilagan.  Cabaruan is bounded on the east by the barrios of Alicaocao, Turayong , and the Cagayan river. On the west by a running stream called Turko Creek. On the north by Manga and Tagaran, and on the south by the town proper.

            This barrio was officially organized in the early part of 1937. Before this date there were some families already found here. They were the Dalupang, Abad, Gauiran, Fajardo, Sales, Respicio, Del Rosario and Collantes families. They acquired their lands thru homesteads. Unfortunately a very destructive flood in December, 1936 occurred. Many barrios were flooded to the house tops. Animals, products, lives and properties were lost. So the people from the nearby barrios of Cabaruan such as Mabantad and Duminit transferred to Cabaruan. Some land owner sold pieces of land. Even strangers from the places began to like the place.

            Over the peaceful little barrio reined the following Tenientes: Del Rosario, Gauiran, Fajardo, and Sales. They are just simple people with intelligence.

            While opening the provincial road to Ilagan the personnel of the Bureau of Public Works made cemented well for the workers use. It is located near the small cemented bridge. Up to the present the well is still of use to the families living near it. The first biggest house in the barrio was built by the family of Gauiran.

            During the early American occupation it was in this place where the American soldier kept and grazed their houses. During the World War II, Japanese soldiers stayed in the house of this barrio. A big wooden house owned by Japanese just at the junction going to Ilagan was the Japanese checkpoint. All people coming from the barrios along the Cagayan River, strangers from downstream and other people from various places had to stoop to this place to show the Japanese flag pinned on their clothes and to greet the officers of the day. Suspected guerillas and owners of the pistols guns were also detained in this place tables and fruit trees. Truck buyers can easily buy their products. Some of the lands are not cultivated because most of the people living in this barrio are laborers, laundry women and employees.
