Lekopancing Dam is an infrastructure that has the function of providing water supply for irrigation demand. To prevent a water availability deficit, a water balance analysis is conducted. This analysis will compare the need and availability of water, especially for irrigation. The purpose of this study is to analyze and determine the level of water availability at Lekopancing Dam for agricultural purposes in Maros Regency. Analysis of water availability with the water balance method is based on effective rainfall data, actual evapotranspiration, potential evapotranspiration, mainstay discharge, NFR of rice fields and irrigation water needs in the range of 2013-2022. The results showed that water availability in the December to July period I, tended to be greater than water demand, with the highest water availability of 22.02 m3/s. The highest water demand occurs in the August-November range and a deficit of 11.35 m3/ s. The potential availability of water for irrigation needs at Lekopancing Dam is quite large because the water deficit is small and occurs at the end of the growth period or entering the harvest period.
