Reservoirs
Reservoirs = artificial water bodies
The data show the change in area of reservoirs surface water. Change in reservoir area is represented as either gain arrow_drop_up or loss arrow_drop_down measured as a percentage
and km2 units. Total change in extent is calculated by comparing the most recent annual data to a five year (2000-2004) baseline. The minimum reservoir extent corresponds to the minimum surface area of the reservoir that is continuously
observed as water throughout the whole year. This minimum extent varies from one year to another and is related to the balance between the reservoir's water input (rainfall, glacier melting) and output (water consumption). The minimum
extent of each reservoir is continuously monitored with data updated annually. The maximum reservoir extent corresponds to the highest observed extent a reservoir reaches. The maximum extent also varies from one year to another. The maximum
extent of each reservoir is continuously monitored and updated annually. The difference between the minimum and maximum extent for a specific year corresponds to the seasonally flooded extent, occurring due to seasonal water level oscillations.
