Most abandoned mining ponds are suitable as retention or detention ponds. The pond chosen in this study satisfies the characteristics to be used as retention or detention pond. Shown by it locality, capacity, inlet and outlet facilities for the catchments considered in the study. The design rainfall was obtained from MASMA manual IDF curves using Bagan Scrai town design storm coefficients. Time-series rainfall data which was obtained from Jabatan Pengairan dan Saliran (JPS) is analyze to obtained new rainfall intensity. The design discharges for inflow and outflow from the pond was obtained by using manual and computer modeling methods. The result shows that the design rainfall intensity is more conservative than that observed data. The result from the two methods used for design discharge was compared and analyze. It was found that the abandoned mining pond volume is adequate to cater stormwater management. The volume of retention pond given by MIDUSS modeling is higher compare to the manual calculation. Abandoned mining pond has yet to be looked at positively, with proper planning and political will it has the potential to be developed into prime real estate in the future.
