dams are 15 meters or more in height. Dams that are between 10 and 15 meters in height are treated as large dams if they present special design example, an unusually large flood-handling requirement, location in a zone of high seismicity, foundations that are complex and difficult to prepare, or retention of toxic materials. Dams under 10 meters in height are treated as large dams if they are expected to become large dams during the operation of the facility. Information in this guide concerns small dams that do not meet the ICOLD (1974) definition of a large dam given above. It does not provide guidance for excavated ponds as they do not represent a safety concern and they generally do not have an embankment associated with them. Dam Management in In , the Ministry of Natural Resources (MINIRENA) is in charge of water resources. It defines national water policy and establishes a national master plan and management of water resources. The Ministry of Agriculture and Animal Resources (MINAGRI) and the Ministry of Infrastructures (MININFRA) are the main institutions using water resources. MINAGRI, is responsible for the planning and design of dams for Agriculture purposes while MININFRA is responsible for the planning and design of dams for Water Supply and Hydropower purposes. However some dams are planned as multipurpose in both Ministries. During the design phase, the Ministries usually adopt industry accepted standards of dam design. No formal guideline/document has been prepared about how dams are designed, operated and maintained. For the dams under MINAGRI, operations of schemes and maintenance of irrigation infrastructures are planned to be handled by the farmers through Water Users Associations (WUAs). Minor maintenance works such as removal of silt and weeds from canals and rebuilding of temporary diversion structures are done by the users’ own initiatives at the beginning of the irrigation season. Major maintenance works that require input of experts and materials are handled by MINAGRI. In 2010, the Irrigation and Mechanization Task Force was established under MINAGRI to carry out the operation and maintenance of water and irrigation infrastructures among other duties. Dam ownership Dam owners are responsible for the safety and the liability of the dam and for financing its upkeep, upgrade, and repair. The common legal understanding is that the dam owner is the developer of the dam, and is therefore responsible for the potential impacts, which the impoundment of water may have on upstream or downstream life, property and environment.
