Lake Victoria is relatively shallow for its size: its average depth is about 40–41 meters (around 130 feet), and its maximum depth is about 80–84 meters (roughly 260–276 feet).

Quick Scoop: Lake Victoria Depth

Lake Victoria is Africa’s largest freshwater lake by surface area, but it sits in a shallow depression rather than a deep rift trench. That’s why its maximum depth is modest compared to its huge surface.

Key depth facts

  • Average depth: about 40–41 m (≈130 ft).
  • Maximum depth: roughly 80–84 m (≈260–276 ft), depending on the survey.
  • The deepest areas are toward the eastern part of the lake, closer to the Kenyan side, while western and southern shores are generally shallower.

Think of it this way: by area it rivals a small country, but by depth it’s more like a gently sunken plateau than a steep mountain valley lake.

Why different numbers exist

Over the years, surveys have reported slightly different maximum depths, usually in the 80–84 m range. Modern bathymetric mapping (tens of thousands of depth points) largely confirms this “around 80 m” picture, with small variations due to methods and reference levels.

So if you’re answering “how deep is Lake Victoria?” in one line, the most accurate short answer is:

Lake Victoria is about 40 m deep on average and around 80–84 m at its deepest point.
