The River Lumi (also Lomi or Luffu) is located in Rombo District, Kilimanjaro in northereast Tanzania and a small part in southern Kenya in Coast Province. It originates on the east side of Mawenzi peak on the east side of (Mount Kilimanjaro), and flows so close to the River Rombo as almost to form a fork. The Lumi, however, maintains its southerly direction, and may thus be said to represent the upper course of the Ruvu, one of tho two main sources of the Pangani River. It flows around the Lake Chala and the Taveta town in the west and empties into the Lake Jipe. [1] The fish species Barbus sp. 'Pangani' has only been found in the river's N'joro Springs, situated in the upper Pangani River drainage basin.

Wetland management

Most water taken from the Lumi is from the section that flows through Kenya. [2] After the building of several dams along the Kenyan side of the Lumi, and with several periods of reduced rainfall, the dry up of Lake Jipe became a concern, necessitating wetland management programs. [3] During the period of 2004-2006, the United Nations Development Programme GEF Small Grants Programme and the Biodiversity Conservation Programme of the European Union have completed a de-siltation and restoration project of the river's original course.

Africa is a continent comprising 63 political territories, representing the largest of the great southward projections from the main mass of Earth's surface. Within its regular outline, it comprises an area of 30,368,609 km2 (11,725,385 sq mi), excluding adjacent islands. Its highest mountain is Mount Kilimanjaro, its largest lake is Lake Victoria.

Nile Major river in northeastern Africa

The Nile is a major north-flowing river in northeastern Africa. It flows into the Mediterranean Sea. The longest river in Africa, it has historically been considered the longest river in the world, though this has been contested by research suggesting that the Amazon River is slightly longer. The Nile is amongst the smallest of the major world rivers by measure of cubic metres flowing annually. About 6,650 km (4,130 mi) long, its drainage basin covers eleven countries: Tanzania, Uganda, Rwanda, Burundi, the Democratic Republic of the Congo, Kenya, Ethiopia, Eritrea, South Sudan, Republic of the Sudan, and Egypt. In particular, the Nile is the primary water source of Egypt, Sudan and South Sudan. Additionally, the Nile is an important economic river, supporting agriculture and fishing.

Nyumba ya Mungu Dam is a Tanzanian, hydroelectric dam located in Mwanga District, Kilimanjaro Region. It was built in the late 1960s and is Kilimanjaro regions largest artificial water body. Nyumba ya Mungu Reservoir. Nyumba ya Mungu means 'House of God'. Its installed capacity is 8 megawatts (11,000 hp).

Ewaso Ngiro

Ewaso Ng'iro is a river in Kenya which rises on the west side of Mount Kenya and flows north then east and finally south-east, passing through Somalia where it joins the Jubba River. The upper basin of the Ewaso Ng'iro River is 15,200-square-kilometre (5,900 sq mi). The river has a continuous water supply due to the glaciers on Mount Kenya. Ewaso Ng'iro feeds into Lake Ol Bolossat, the only lake in Nyandarua county and the larger Central Kenya. Ewaso Ng'iro crosses seven arid to semi-arid landscapes. It is characterized by vastly different physiographic features and species and has become a fundamental component to the survival of the wildlife, as well as the expansion of human population and socio-economic developments. Water, the limited land resource provided by the Ewaso Ng’iro watershed is unevenly distributed throughout the higher and lower regions of the catchment due to the large percentage necessary to maintain agricultural practices and climatic changes.

Barbus sp. 'Pangani' is an undescribed but distinct freshwater fish species in the family Cyprinidae. Apparently a close relative of the East African red-finned barb, it is currently under study for its formal description. Until then, this small African barb is provisionally assigned to the genus Barbus, but probably belongs – like "B." apleurogramma – in another genus.

The Pangani suckermouth is a species of upside-down catfish native to Kenya and Tanzania. This species grows to a length of 7 centimetres (2.8 in) SL.

<i>Ctenochromis pectoralis</i> Species of fish

Ctenochromis pectoralis, the Pangani haplo, is a species of fish in the family Cichlidae. It was originally characterized in the Pangani River of Tanzania, and may also be present in Kenya. It is listed as extinct by IUCN as a result of a 1996 evaluation, but this appears to be incorrect. A more recent IUCN publication stated that this species is not endangered in any way.

Oreochromis esculentus, the Singida tilapia or Graham's tilapia, is a critically endangered species of cichlid endemic to the Lake Victoria basin, including some of its satellite lakes such as Kyoga, in Tanzania, Uganda, and Kenya. Its common name refers to Lake Singida, but this population is the result of an introduction that happened in the 1950s. This fish is highly valued by local fishermen, who know it as ngege.

Oreochromis jipe, the Jipe tilapia, is a critically endangered species of cichlid fish native to Kenya and Tanzania, where it is restricted to Lake Jipe and the Pangani River. The population in the Pangani River shows some morphological differences compared to the population in Lake Jipe, and it is sometimes recognized as a separate species, the Pangani tilapia. Whether regarded as one or two species, the Jipe–Pangani tilapia forms a species flock with the threatened Lake Chala tilapia from the same general region of Kenya and Tanzania.

The Pangani robber is a species of fish in the family Alestidae. It is found in the Tanga and Pangani River drainages, including Lake Jipe, in Tanzania and Kenya. Its natural habitats are rivers and lagoons.

Lake Jipe Lake in Kilimajaro Region, Tanzania and Kenya.

Lake Jipe is an inter-territorial lake straddling the borders of Kenya and Tanzania. On the Kenyan side, it is located south of the village of Nghonji while on the Tanzanian side, it is situated within Mwanga District, in Kilimanjaro Region. The lake is fed mainly by the Lumi River, which descends from Mount Kilimanjaro, as well as streams from the North Pare Mountains, being on the leeward side. The lake's outlet forms the Ruvu River. Kenya's unfenced Tsavo West National Park protects part of the lake's northern shore, while on the Tanzania side Mkomazi Game Reserve is nearby. The lake is known for its endemic fish, as well as water birds, mammals, wetland plants and lake-edge swamps, which can extend 2 kilometres (1.2 mi) from Jipe's shore.

Pangani River River located in northeastern Tanzania

The Pangani River (pin-gi'nee) is a major river of northeastern Tanzania. It has two main sources: the Ruvu, which rises as Lumi at Kilimanjaro, passes through Lake Jipe, and empties into the Nyumba ya Mungu Reservoir, and the Kikuletwa, coming from the west and mainly fed by Mount Meru in Arusha Region, which also enters into the Nyumba ya Mungu Reservoir in Kilimanjaro Region. Just after leaving the reservoir the stream becomes the main Pangani, which empties into the Indian Ocean in Tanga Region at the Tangan port town of Pangani.

Yala River

The Yala River is a river of western Kenya, a tributary of Lake Victoria. It generally flows fast over a rocky bed through a wide valley before joining the Nzoia River to form the Yala Swamp on the border of Lake Victoria. The land along its course is mostly cultivated or used for grazing, with relatively few remnants of the original forest. Soil erosion is visible throughout the river basin, particularly in the lower parts. Projects are underway to exploit the river for hydroelectricity.
