Reservoir Hazard Map
About the Reservoir Hazard Map
The reservoir hazard map illustrates hypothetical flood zones in the event of a breach in a full reservoir, as well as evacuation sites and how long it would hypothetically take for the water to reach certain areas. The map was created to help raise awareness of disaster preparedness among local residents, as well as to help reduce the amount of damage in the case of a disaster through mobilizing residents for rapid and accurate evacuation. Please take time to talk as a family and as an area about what to do in the unlikely event of an emergency, and participate in evacuation drills.
The hazard map is still currently being created, and will be added to the page as sections are completed.
(Note) This hazard map hypothesizes water breaching a full reservoir due to an earthquake. However, there is a possibility that areas besides those marked on the map could become inundated due to rainfall, the reservoir’s water volume, the degree of damage to the dam body, land use of the surrounding area, etc. Please make preparations so that you will be able to evacuate quickly and at the appropriate time depending on the situation.
Standard for Selecting Agricultural Reservoirs Important to Disaster Preparedness
- Homes, public facilities, etc., are in the flood zone within 100 meters of the reservoir
- Homes, public facilities, etc., are in the flood zone 100~500 meters from the reservoir, and the reservoir has a max storage volume of at least 1000m3
- Homes, public facilities, etc., are in the flood zone 500+ meters from the reservoir, and the reservoir has a max storage volume of at least 5000m3
- Those that do not qualify by the standard listed above but have been deemed necessary by the prefecture or municipality due to the reservoir’s scale, structure, or topographical conditions, the positioning of houses, public facilities, etc., in regards to the reservoir, the conditions of its maintenance and management, the conditions of the region upstream from the reservoir, the soil quality and topography of landslide areas, etc.
