Davit Kecils Dam is an irrigation area that located in Ulu Maras Village, East Jemaja District, Kepulauan Anambas Regency, Kepulauan Riau Province. The need of geotechnical study is important to determine the soil properties and soil stability of the study area. Methods used are field study by taking soil samples and laboratorium test such as atterberg limits analysis, sieve analysis and direct shear stress that useful for soil resistence identification. Based on laboratorium test result, the range of Wl value is 49,28 - 95,55%, range of Wp value is 26,19 - 33,79% and range of Ip value is 20,21 - 58,76%. in the other hand, Hb.2, Hb.3, Hb.6 and Hb.7 are non plastic soils. The range of direct shear stress (phi) obtained are 25,33 - 34,33. Soil grain size identified from sieve analysis is gravel - clay. Based on the analysis result, stability of davit kecils dam that was observed from normal water condition and flood water condition are categorized into strong-safe dam characterized by sufficient eccentricity an bearing capacity control. In addition, the dam is withstand rolling and sliding.
