This paperIn this study, we evaluated the suitability of the location of small reservoirs in the Bodri-Kuto watershed using the monthly standardized precipitation index (SPI). In the Bodri-Kuto watershed there are 33 small reservoirs (10 are already in operation and another 23 are under design and construction). The study of the impact of these site changes on the location suitability of small reservoirs in the Bodri-Kuto watershed has been studied by [3], showing that small indicated their low suitability [3].
3] used SPI to evaluate the correlation between the drought area and the location of small reservoir construction in Indonesia's Bodri-Kuto basin. In this analysis we use the driest three months, i.e. the month: July, August and September. Frequency of rain stations with moderately dry or worse conditions in the Bodri-Kuto watershed.
Monthly SPI in the driest months of July, August and September in Bodri‐Kuto. The spatial distribution of monthly drought in the Bodri-Kuto watershed during July, August and September is presented in Figure 8.

AUTHORS' RESPONSES TO REVIEWER'S COMMENTS (REVIEWER 1)
In hilly areas, such as those in the middle and upper reaches of the Bodri-Kuto watershed, variations in monthly rainfall can be large. Therefore, the use of monthly SPI in an area of highly variable precipitation may still be relevant even at a short distance. Figure 9 shows two types of reservoirs, namely those already built (10 reservoirs) and those still in operation (23 reservoirs).
10 Sidokumpul is inside the constructed tank, the location of which is barely in the middle of the Figure (see the sign: black dot in the small circle to build), the upper side of the text "Patean Curug". While tank number 15 and 17 located in the upper left part of the picture is inside the tanks in progress (see the sign: white cross inside the small black circle).

Title Site suitability for small reservoirs in the Bodri-Kuto catchment area based on spatial monthly SPI. Summary Despite efforts to develop and conserve water resources, some areas in Indonesia's Central Java province still experience water shortages almost every year during the dry season, especially in rural villages. The government of Central Java has committed to implement a program of building 1,000 small reservoirs by 2020 to overcome water shortages.
However, the technically ideal sites are mostly privately owned, which requires long and expensive land acquisition. To avoid the uncertainty of land acquisition, some small reservoirs were placed on government-owned land, which did not require land acquisition. The shift from technically ideal sites to available state-owned land for the construction of small reservoirs has called into question the siting suitability of those reservoirs.
In this study, we assessed the suitability of the location of small reservoirs in the Bodri-Kuto Watershed using the standardized monthly precipitation index (SPI). We used the rainfall data of 25 stations in the watershed from 2000 to 2016 and analyzed the annual and monthly rainfall data. Annual analysis shows that dry conditions (SPI < -0.5) from 2005 to 2009 affected more than half of the rainfall stations (>50%), while rainfall stations that experienced drier years included Kedung Wungu, Babadan, Bojong , Ketapang, Sekopek and Podovaras (more than 9 out of 17 years).
The monthly SPI shows that all rain stations experience moderately dry or worse conditions in July, August and September (SPI < −0.50). Overlaying the spatial distribution of arid conditions with the location of small reservoirs can be used to evaluate the suitability of small reservoir sites. The findings indicate that the spatial distribution of SPI can be used as an additional criterion for evaluating the suitability of small reservoir sites, should technically ideal sites not be available.
REVIEW REPORT FORM
The subject of this study is to suggest the reservoir location suitability through SPI analysis. In the case of the drought index, various indices are currently proposed, and in addition to the SPI, using the drought index considering the amount of evapotranspiration in the target region is also worth proposing. The conclusions must be described specifically in this study for uncertainties and new findings.

ROUND 2
The only thing that I think would improve the paper is, as requested during the original review, a map, accompanying Figure 1, to show the area of study on a larger scale. In the second revised article I already give the figure on a larger scale with the previous figure 1.
