In 1901-1912 the Americans captured Barangay Supang. A US reservation camp known as Camp Jossman was established. It was composed of regiment of American soldiers and two (2) battalions of the Philippine Scouts. They were responsible for the construction of Sto. Rosario Wharf, Gen. Douglas MacArthur then fresh from US Military School made Supang as their headquarters. Many recreation centers were established in this place. However, in 1912, an order from the US high command came to vacate Camp Jossman and return to the US; all the structures then that were established during the stay of the American soldiers were all demolished.
It is now being used by Water District of Buenavista as water reservoir.
