Studies on the ecology of Lake Sare (Kenya) were carried out to provide baseline information on the ecological conditions before a major wetland reclamation project was started upstream of the lake. Results indicated that maximum depth had decreased by 0.9 m while Secchi depth readings had decreased by 0.1 m compared to historical values. This implies that the lake was undergoing siltation. pH values had increased from 6.80 to 7.58 reflecting increased primary production. Conductivity had increased from 106 – 137 2 ~kS/cm. NO3- N and PO4-P had significantly increased from 0.8~kg N l-1 and 0.14 ~kg P l-1 to 23.90.8~kg N l-1 and 34.80.8~kg P l-1 respectively while chlorophyll a values reached 34.8 ~kgl-1. The macrophyte environment was dominated by Cyperus papyrus, Eichhornia crassipes, Phragmites australis, Cyperus papyrus, Eichhornia crassipes, Phragmites australis. The invasion of the lake by Eichhornia crassipes is reported here for the first time. The study further observed macrophy.....
