Surface water in Ward 7, Nkandla
In 2025, Ward 7, Nkandla had 0.03 km² of open water on average, none of it nearly all year. The wettest year since 1984 was 1994 (0.15 km²); the driest 2003 (none).
Open water seen on the ground from space: dams, lakes, rivers wide enough to see, pans, wetlands with open water and flooded fields. Each year, the Landsat satellites look at every 30 m spot many times; where the sky is clear, each look says water or not. The average water area counts each spot for the share of its clear looks that were wet. Permanent water was wet in more than 80% of the clear looks; seasonal water was wet at least once but less often than that.
What it isn’t: not how full a dam is (that is the Department of Water and Sanitation’s weekly level, by volume), not groundwater, not rain, and not water in pipes or tanks. Narrow rivers, water under trees or bridges and anything smaller than about 30 m are missed. A year with few clear looks (cloud, or the early years when fewer satellites flew) is less sure, and 1988 is missing everywhere because Digital Earth Africa does not have it: a missing year is left out, never counted as dry.

Among the 40 years in which at least 90% as much of the place was seen as in its best year (1 less well seen year is left out), so a cloudy year cannot pass for a dry one.

A year missing from the table is one Digital Earth Africa does not have for this place (1988 everywhere, 1985 in some places).
