Lake Jipe is a small, shallow lake (area 28 sq. km and average depth less than 3 m), lying astride the Kenya-Tanzania border, just to the east of the northern Pare Mountains of Tanzania (Mwanga district, in the Kilimanjaro region). 

It is 12 km long and 2.5 km wide, 12 square km belong to Tanzania and 14 square km to Kenya. Tsavo West National Park of Kenya borders the southern portion of the lake while Mt Kilimanjaro dominates the horizon some distance to the northwest.

Lake Jipe receives its main inflow from Mt 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, located 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 hippo and crocodile but there is also a small herd of zebras, To the northern end of the lake are also a few tiny villages whose inhabitants make a living from fishing.
