The Feasibility study potential of small dams in Semarang District has identified 8 (eight) urgent potential small dams. These potential dams must be constructed within 5 (five) years in order to overcome the problem of water shortage in the district. However, the government has limited funding source. It is necessary to select the more urgent small dams to be constructed within that limited budget. The purpose of the research is determining the priority of small dams’ construction in Semarang District under limited budget condition. The method used in this study is Cluster Analysis, AHP and Weighted Average Method. The criteria used to determine the priority in this study consist of: vegetation cover in the inundated area, volume of embankment, land acquisition area, useful storage, reservoir's life time, water cost/ m3, access road to the dam site, land status at abutment and inundated area, construction cost, operation and maintenance cost, irrigation service area and raw water benefit. Based on results of Cluster Analysis Method, AHP Method and Weighted Average Method can be concluded that the priority, therefore the sequences, of small dams construction are: 1) Mluweh Dam (0,165), 2) Pakis Dam (0,142), 3) Lebak Dam (0,134), 4) Dadapayam Dam (0,128), 5) Gogodalem Dam (0,119), 6) Kandangan Dam (0,114), 7) Ngrawan Dam(0,102) and 8) Jatikurung Dam (0,096). Based on analysis of the order of priority of 3 (three) method showed that AHP Method is more suitable than Cluster Analysis and Weighted Average Methods, because the result of AHP Method is closer to the conditions of each dam in the field.
