This paper presents the results of the water audit of the Hadejia river sub-catchment of the
Komadugu Yobe River basin of Nigeria (KYB), available water was compared with existing and
potential water demand; results shows that about 2,619 million cubic meters (MCM) of surface water
is available annually upstream of Wudil (HS 1), 658 MCM is available between Wudil and Hadejia
(HS 2), while 905 MCM is available between Hadejia and Gashua (HS 3). Analysis of direct ground
water recharge revealed that 86mm, 94mm and 8mm of water is recharged to groundwater annually in
the three hydrological sections HS 1, HS 2 and HS 3 respectively. It is obvious that the least ground
water recharge takes place in the Hadjia - Nguru Wetlands which is natural flood plain renown for its
Analysis of water demand show that there is presently no water stress in the sub catchment
since the available water is in excess of demand, the potential water balance of the area shows that
about 75% of the available water between Wudil and Hadejia section would be used up by 2010 going
by the current development rate. Projections show that the water use rate will reach 100% by 2018. At
this time, water scarcity will be experienced in this sub catchment if urgent steps are not taken to
address the situation. Integrated water resources management (IWRM) strategies were advanced for
the sub catchment in order to avert the crisis.
