Flood Check
Nairobi flood, 5 to 8 Mar 2026
Grogon: how deep did the water get?
In the Flood Check model of the Nairobi flood of 5 to 8 March 2026, the wettest tenth of Grogon had 82 cm of water or more (thigh deep), with the most water at Sun 8 Mar, 04:00. Most of the area stayed under 10 cm.
The model has no river channels: water that reaches a river valley stays there, so depths beside the Nairobi, Mathare and Ngong rivers are higher than the real water was. It has no blocked drains either. Check the exact street.
