Abstract: In a complex karst area,the leakage and evaluation about construction conditions of reservoir are the key of the preliminary prospecting to build a reservoir. The karst leakages in Saihai Lake reservoir are very developed. Based on the serious analysis and evaluations of the hydrogeological and engineering geological conditions in project area,the authors carried out a series of tracer tests,found the main channel of karst leakages;then,determined the water balance calcula-tion area,established the water balance calculation model,calculated the reservoir leakage under current conditions,and estimated the possible leakage of reservoir after water storage. After all,the authors pointed out that the reservoir leakages were very serious in the front of the reservoir where must take large-scale steps to prevent it happening,and to meet the design requirement.
