|Lake Victoria is the most important natural resource in the Sub-Saharan region of Africa. It is the
second biggest fresh water lake in the world, and has a surface area of approximately 69.500 km2 (26.800 square
miles) with an adjoining catchments area measuring 184.000 km2. The
Kenyan share of the Lake is 6% while Uganda has 45% and Tanzania 49%. The surrounding lake communities in the riparian states
(Tanzania, Uganda and Kenya) is approximately 30 million, with a large proportion being totally dependent on the lake for
water, food and economic empowerment.
The Source of the Nile.
Despite it’s vast size, Lake Victoria, remained one of the last physical
features in Africa to be discovered by the 19th century explorers from Europe. The early charts of Ptolemy delineate
a vague patch of water lying to and east of the “Mountains of the Moon”, but it was not until August 1858 that
Mr. Speke and Mr. Burton stumbled to its southern shore near Mwanza. Mr. Speke later wrote that he felt no doubt that the
lake he had stumbled upon gave birth to that interesting river, the source of which had been the subject of so much speculation,
and the object of so many explorers. He further wrote; the lake at my feet is the most elusive of all explorers’ dreams,
the source of the legendary Nile.
Depth, Water Temperature and
Lake Victoria is relatively shallow and has a gentle slope on the shores hence
any slight change in Lake Level “affects a considerably large land area”.
The lake has a mean depth of about 40 meters, with the deepest part at 82 meters. The range in water temperature in
the Lake lies within the range in air temperature during a significant portion of the year. it is important to note that the
water balance in Lake Victoria is dominated by evaporation and rainfall in the lake; with minor contributions from river inflow
and outflow. The outflow of water, into the River Nile through the Owen Falls Dam, account for only 20 per cent of water loss
from the lake. The remaining 80 per cent is taken by evaporation. Similarly, the inflow through the many rivers from the catchments
area only contributes 15 - 20% while rainfall on the lake accounts for 80 - 85%. Of the inlets, the River Kagera, which flows
from Rwanda, contributes about 46%, Kenya’s River Nzoia and Sondu/Miriu River about 15% (Top of Page)
The wide variety of fish in Lake Victoria is
an interesting evolutionary phenomenon – more than 200 species of haplochrominas has evolved in the lake. Scientifically,
it is puzzling that so many diverse species unique to these waters could evolve in so uniform an environment. Evolutionary
biologists speculate that, hundreds of thousands of years ago, the lake may have dried into a series of smaller lakes causing
these brilliantly coloured cichlids to evolve differently. These fish are greatly sought after for aquariums. One unique characteristic
for which cichlids (tilapia being the best known) are noted for is the female’s habit of nursing its fertilized eggs
and young in its mouth. To the people of Lake Victoria, the cichlids have been their livelihood – the catch, preparation
(sun-drying) and sale of these fish fit well within the resources available to them.
"The Ecological Disaster".
Lake Victoria appears to be a classic case of wrecking an ecological
community by introducing a predator – the Nile perch. The perch was introduced into the lake some 20 years ago, probably
for sport, and has come to dominate the lake. Although people argue how the voracious Nile perch came to be there, most believe
that it has been an ecological disaster eating most of the smaller native fish. However, some scientists and biologists now
have evidence that the perch is not wholly responsible for the rapid decline of the number of the smaller fish. A survey has
shown that in most places the biologists found few cichlids and many Nile perch. But in some places they caught hundreds of
specimens of many species, not only cichlids but also other species believed to be in decline. Nile perch were present in
the same catches, often in large numbers. The areas that were rich in cichlids were all reserves, where fishing is banned.
Close by, where fishing is allowed, the cichlids were rare. This evidence suggests that over-fishing with fine-meshed nets
is partly to blame for the “ecological disaster” in Lake Victoria.
WOOWW!, WHAT A WONDERFULL SITE YOU WILL SEE ...WELCOME

a light in Mbita our small Town on the shores of Lake Victoria, go through the cause way and reach Udogo youth development
group on the other side of the Island.
magnificent lake is not only the source of the Nile, but is also the largest body of fresh water in Africa, and second largest
in the world after Lake
Superior. It is bigger than many countries.
Uganda and Tanzania
all border the lake with only 5of it being Kenyan territory. Trade is carried out across the water, often in traditional dhows
- which don't always look seaworthy! However, these craft have carried people and commodities up and down this lake for hundreds
Visiting one of the offshore islands is a truly wonderful way to relax in between game-watching safaris.
A light breeze keeps most biting insects away and blows gently through the simple stone or wooden waterfront cottages.
Island and Mfangano Island have enchanting peaceful camps right on the water's edge and both are most often accessed by a
half-hour light aircraft flight from the Masai Mara, Wilson Airport in Nairobi and other destinations which can bring you
to the islands.
people come here for some relaxing fishing, but it can become quite a fight when you have a Giant Nile Perch on the end of
your rod. Casting from the shore at dusk for much smaller Tilapia is a more composed affair. Both can be cooked for a delicious
dinner by your lodge chef. Locals fish at night with lanterns to attract the tiny silver Kapenta sardines, which are brought
back early in the morning and laid out in the hot sun to dry.
the ornithologist or anyone who loves to hear the distinctive cry of Fish Eagles, Lake Victoria's
birdlife is staggering. There are huge nesting colonies of egrets, gannets and cormorants, and pairs of vocal Fish Eagle who
patrol their territories every 100 meters especially when you float near mbasa
Islands Towards Takawiri.
visit to Lake Victoria is highly recommended towards the end of a Masai Mara safari, Ruma
National park and other Kenyan National parks. It will refresh you and
give you the energy you need for more early morning game drives. Udogo group members can be of good guide to your travels
and visiting times.
