The purpose of this webpage is to communicate to the public and Mekong water users the work of the MRC in implementing the Procedures for the Maintenance of Flow on the Mainstream (PMFM) of the Mekong River. It displays daily water flows during the wet and dry seasons at each of the selected 9 hydrological stations along the mainstream. It is part of an information system for flood and drought monitoring and the implementation of actions related to emerging flow situations that are critical.
The intent of the 1995 Mekong Agreement of the four lower Mekong countries is to promote cooperation on the sustainable development and management of the Mekong River Basin’s water and related resources. The intent of the PMFM is to cooperate on the maintenance of a mutually acceptable hydrological flow regime on the mainstream to optimize the multiple uses and mutual benefits of all riparian countries and to minimize the harmful effects.
To cooperate in the maintenance of the flows on the mainstream from diversions, storage releases, or other actions of a permanent nature; expect in the cases of historically severe droughts and/or floods:
The Joint Committee shall adopt guidelines for the locations and levels of the flow, and monitor and taken action necessary for their maintenance as provided in Article 26.

The PMFM for planning purposes by undertaking assessments of future developments (scenarios or projects) to predict whether those future developments would result in mainstream flow conditions that are within the agreed acceptable limits.
The PMFM for monitoring purposes, is directed at:
