The proposed dam is located at Crocodile Jaws site approximately 18km from Oldonyiro shopping centre and on the border of Isiolo and Laikipia counties. The proposed dam is intended to regulate the flows of the Ewaso Nyiro River, supply water to Isiolo town, the proposed Isiolo resort city and rural areas of Isiolo, Laikipia and Samburu counties. The project will also generate 16MW of hydropower.
The project will serve a population of about 220,726 people in the initial year 2020, 343,560 people in the future year 2030 and 564,819 in the ultimate year 2040. The projected water demand is 7,894m3/day for the initial year 2020, 18,957m3/day in the future year 2030 and 60,000m3/day in the ultimate year 2040.
