The Tondano river located in special economic growth area between three towns that is which lies Tomohon as, an agricultural and tourism town Bitung as a port and industrial town and Manado as a commercial town, what recognized as KAPET TOBIMA. The Tondano river is the only outlet from lake Tondano having total width 466,4 km2 flows along the length of 44,4 Kms having estuary in Manado bay. The Tondano river is one of potencial water resource which now exploited for drinking water. The prediction of increasing wwater need especially in domestic, municipal and industrial ( DMI) and Energy in the future comes with the decrease of water resource, hence need some anticipative effort since early dayswith water resources management and government strategy, so that we can exploited it in an optimal way. The yearly Rainfall in this area has ranges from 778 mm up to 5238 mm, and by using water availability analysis method like Water Balance, FJ. Mock and NRECA, these methods will simulate the monthly equilibrium water at one particular catchment area which will be posed at calculating total run-off by using monthly rainfall, evapotranspiration, humidity of soil, and ground water supply. The average water availability of this area per year is 6.17 M3/sec, whereas the water demand for projection until the year of 2025 is 2.13 M3/sec, indicating there is still having surplus of water. In allocation of water for intermediate term and long term is required an effort of water resources development for accomplishment the requirement of intermediate term and long term, where need to be allowed for building an reservoir for PLTA.
