- GENERAL INFORMATION
Lake Naivasha which is a freshwater lake in a complex geological combination of volcanic rocks and sedimentary deposits from a larger Pleistocene era lake. It is on the floor of the East African Rift Valley; it is at an altitude of more than 1,800 m. Birdlife is particularly abundant (over 460 species). Crescent Island in Lake Naivasha is part of the rim of submerged volcano whose crater forms the deepest part of the Lake. Apart from transient streams, the lake is fed by the perennial Malewa and Gilgil rivers. There is no visible outlet, but since the lake water is relatively fresh it is assumed to have an underground outflow The lake and its surrounds are rich in natural bounty, and the fertile soils and water supply have made this one of Kenya’s prime agricultural regions. Lake area varies greatly according to rainfall, with an average range between 114 and 991 sq kms. At the beginning of the 20th Century, Naivasha completely dried up and effectively disappeared. The resulting open land was farmed, until heavy rains a few years later caused the lake to return to existence, swallowing up the newly established estates.
Naivasha has a tropical savannah climate with one distinct and one less distinct rainy period. In between these two periods there still is a chance of reasonable amounts of precipitation. Because of the altitude temperatures are slightly lower on average; nights may be cold.
The lakeshore retains some patches of fairly unspoilt savanna and woodland Much of the lake is surrounded by forests of the yellow barked Acacia Xanthophlea, known as the yellow fever tree.
It is a breeding ground for cormorants all year round. You might see pelicans and spoonbills perched on the dead trees and almost certainly the fish eagle. There are two species of fish breeding in this fresh water lake, black bass and tilapia. The tilapias are ‘mouth breeders’, the various species of fresh water mouth breeders are known as “tilapia”. Large and small frogs are abundant, from the bull frog to the tiny tree toad. Other birds are Black Herons , Grey-backed fiscal., Black-lored Babbler, Fischer’s and the Yellow-Collared Lovebird. The lake edge supports dense vegetation which, in turn, supports a thriving bird population including the Grey-capped Warbler, Spectacled Weaver, Brimstone Canary and Red-billed Fire finch.
Lake Naivasha is home to larger grazers such as zebra, impala, giraffe and hippos.
