Rising Waters Swamp Lake Naivasha
Lake Naivasha in Kenya's Great Rift Valley has experienced a rapid rise in water levels over the past decade, increasing by about 7 meters and expanding its surface area by roughly 40 percent. The flooding has inundated homes, flower farms, and infrastructure, and has caused the nearby Lake Oloidien to merge with Naivasha, introducing more saline water into the system. Scientists attribute the changes to persistent rains and monitor the situation using satellite altimetry and Landsat imagery.
- ▪Satellite measurements show Lake Naivasha’s depth rose about 7 meters (23 feet) between 2010 and 2026.
- ▪Landsat images reveal a 40 percent increase in the lake’s area, adding roughly 50 square kilometers of water.
- ▪Flooding has damaged residential neighborhoods, flower farms, roads, and utilities around the lake’s southwestern shore.
- ▪Lake Oloidien has merged with Naivasha, bringing saline, alkaline water into the previously freshwater lake.
- ▪Hydrologist Mathew Herrnegger notes the rising waters are displacing people and threatening the region’s flower trade.
