On 6 October 1993, His Majesty the King gave an initiative to representatives of various government agencies including the Commander-General, 1st Army Area Command, the Director-General, Royal Irrigation Department, the National Park, the Director-General, Wildlife and Plant Conservation Department, the Governor of Prachuap Khiri Khan Province as well as the Secretary-General of the Royal Development Projects Board concerning the enhancement of the water storage capacity of Yang Chum Reservoir in Kui Buri District of Prachuap Khiri Khan Province. The initiative stated that the agencies considered building check dams in the areas above Yang Chum Reservoir to store water for uses which will help retard the water flow to prevent flooding, to maintain soil moisture and to provide water for elephants. The construction of check dams could be done at intervals or of a shape of a water pond or a skull connected with a pipeline system to disperse water and create moisture to the forest which will continue to serve as a food source for the elephants.
