    Abstract: The yield and the reservoir capacity of River Owena in Ondo State were estimated using a combination of the Rippl`s mass curve and the Loucks Sequent Peak Procedure. The yield was found to be 299.99x10<SUP>6</SUP>m<SUP>3</SUP>. However, the reservoir capacity obtained from the mass curve was 125x10<SUP>6</SUP>m<SUP>3</SUP>. This is lower than the yield value and if used for the dam design, there will be a danger of the reservoir capacity not being able to meet the expected demand. Further analysis was done using the Loucks Sequent Peak Procedure. The value from this procedure was 3.30x10<SUP>9</SUP>m<SUP>3</SUP>. This capacity is safe and reliable and will ultimately meet the water demand of the people in the coverage area.
