Lake Jipe is a small, shallow lake lying astride the Tanzania – Kenya borders, just to the east of the northern Pare Mountains of Tanzania in Mwanga district, in the Kilimanjaro region. It is 12 km long and 2.5 km wide, 12 sq. km belong to Tanzania and 14 sq. km to Kenya. Tsavo West National Park of Kenya borders the southern part of the lake while Mount Kilimanjaro dominates the horizon some distance to the northwest. 

Lake Jipe receives its main inflow from Mount Kilimanjaro in Tanzania via River Lumi passing through Kenya. The other main inflow is via River Muvulani from the Pare Mountains. Several temporary streams, mainly from the Pare Mountains, also drain into Lake Jipe. The lake has one outflow, the River Ruvu, found in Tanzania to the south of River Lumi, the main inflow.

Jipe is a shallow backwater of the Lumi river, which afterwards becomes the Ruvu River, and enters in the Nyumba ya Mungu Reservoir. After joining there with the Kikuletwa the stream flows as Pangani River in the Indian Ocean at Pangani.

As for wildlife, Lake Jipe not only offers an abundance of crocodile and hippo but there is also a small herd of zebras.
