To estimate time and floods of the small reservoir (in Indonesian called embung) pursuant to data assumption knew il1l1pstreamneeded by a procedure flood routing. Floods which step into the reservoir will be continued through spillway experiencing change in the form of elementary lengthening or peak time, also degradation of peak flow. The aim of this study is redesign of wide ofspilhvay on Peneda Gandor Reservoir, East Lombok Regency, pursuant to observation of inflow and outflow vallie by flood routing. Flood routing by hydrologis its resolving is based on continuity principle, where inflow average value lessened by the change of storage is equal to outflow average value. Inflow of device is the flood design with return period 100 years, with the outflow to release through crest of spillway. For the same inflow, addition of spillway wide result the water high above of spillway crest is smaller. From result routing at spillway spannedly is beetwen wide 10,0 to 28,0 m, obtained by maximum inflow and maximum outflow value ofB = 10,00 m are I males 275,01 m³/det and Qmales = 205,63 m³/det obtained value ofHmalesis 4,51 m. This means that width B from spillway for Peneda Gandor Reservoir is 10,0 m. Suggested to get detail investigation about the relation between of hydraulic value and economic value at spillway of the reservoir.
