ABSTRACT
Water resource management
includes the optimization of the uses of a dam reservoir for various human
benefits. This study attempts to contribute to a better understanding of the
smallholder irrigation sub-sector by evaluating the water resources and
irrigation potential of Oyun Dam in Offa, North Central Nigeria. The water
resources potential for the dam was analysed by considering the rainfall,
evaporation, population and sedimentation and the irrigation potential by
considering the irrigation command area, using the sequent peak analysis and
the flow duration curve. The potential of using the irrigated land for rice was
also investigated. Rice was used as a preferred crop because it has a high
water requirement. The study revealed that apart from fulfilling its primary
function of water supply, the Oyun dam reservoir has an excess available water
of 2.04*106m3. This is exclusive of all losses based on
reservoir storage capacity, therefore there is an irrigation command area potential
of up to 160 hectares.
Keywords: Irrigation Potential, Oyun dam, Reservoir, Rice production
