The water entering the reservoir varies according to the intensity of the rain. If the intensity of the rain increases, it can cause a rapid rise of water level of the reservoir. To anticipate fluctuations in the water level of the reservoir quickly, adequate spillway capacity is required to channel the inflow discharge with different re-divergence. However, with the increased rainfall intensity, the capacity of the existing spillway is less than satisfactory, so that the water level rise is faster than expected. To anticipate the rapid increase in the spillway capacity check with flood discharge. The research was conducted using curved data of reservoir capacity and flood discharge 2, 5, 10, 25, 50,100, 200, 100, PMF. Based on the calculation results that have been done, spillway capacity operating by 1 door can not flow the maximum flood discharge or Probable Maximum Flood (PMF), thus exceeding the existing reservoir reservoir capacity of 1,236,568,655 m³ and is in elevation 267, an alternative solution that can be taken is an emergency spillway planning that can flow a probable maximum flood (PMF) flood of 1500 m³ / sec which is planned to be 137, 46 m wide, 3 m high and proposed emergency spillway planning location is located on the left side of the main dam} }
