Drought in some regencies of Central Java Province in 2015had disrupted the role of Central Java as a national rice buffer. Theimplementation of reservoir construction program is often constrained onland status issues so that construction implementation takes precedenceover locations that are state land. As directed by WMO to apply the SPImethod in monitoring the drought level worldwide, this study conductdrought index analysis point in Bodri Kuto Watershed using 25 rainfallstations. Drought distribution and drought-vulnerability mapping locationsare implemented by spatial interpolation. The result shows that the peak ofdrought occurred in 2006-2007 and 2015 with an average SPI value of -1.04 to 0.4 (dry - normal). The wet years occurred in 2001 and 2010-2011with an average SPI range of -0.72 to 2.93 (slightly dry - very wet). Theresult of the suitability assessment of the location of the existing andplanned reservoir shows that out of 33 reservoirs there is 6 reservoir (18%)which is highly suitable, 6 reservoirs (18%) ‘suitable’ while 21 otherreservoirs (64%) less suitable. The planned reservoir-construction programneeds to adjust the priority sequence of handling by considering suitabilityto drought-vulnerability locations in addition to criteria.
