In this study, the quantitative effects of the construction of Seymareh Dam in the Karst site of this structure on the fluctuations of groundwater level and discharge of springs have been investigated. According to 10-year measurements in the network of observation wells and springs in this area, it was found that there is a direct hydraulic relationship between the water level of the dam reservoir and the water level of the observation wells. The results revealed a significant difference in the amount of water level of the North Edge wells compared to the South Edge wells, especially in the right abutment and the right abutment wells compared to the left abutment can be seen, respectively, the evidence and confirmation of an Asmari core with Low permeability is along the axis of the anticline and also more efficiency of the sealing curtain on the right side is another reason for this difference. Flow changes in most springs are directly related to changes in reservoir water level and there is a high correlation between those. Changes in the total discharge of the total springs measured on both banks (right and left) have a similar trend to the changes in the discharge of the left bank springs, which is due to the more discharge of the left abutment springs. The results showed that with increasing the water level of the reservoir to 660 meters, the amount of discharge of springs in the region reached 1400 liters per second, and with decreasing the level of reservoir water in the next year this amount decreased and again with increasing level to 704 meters, the amount of discharge to 1800 Liters per second has increased.
