两个大湖位于阿尔巴尼亚东南部，靠近与前南斯拉夫的马其顿共和国（FYROM）的边界，Prespa湖海拔850米（a.s.l）， Ohrid湖海拔695米（a.s.l）。Mali Thate - Galichica山主要由碳酸盐岩溶地层构成，将它们分开。在位于阿尔巴尼亚- FYROM边界的Ohrid湖Tushemisht - Sveti Naum段，利用地下岩溶流对Prespa湖的大泉水进行补给，利用氘和18O的环境同位素数据确定了位于阿尔巴尼亚境内的Tushemisht泉补给的来源。研究结果表明，图什米什特山泉平均流量的52%由Prespa湖补给，48%的流量由Mali Thate - Galichica山降水入渗补给。
Two big lakes are located in southeastern Albania, near the border with Former Yugoslav Republic of Macedonia (FYROM), Prespa Lake at elevation 850 m above sea level (a.s.l.), and Ohrid Lake at elevation 695 m a.s.l. Mali Thate – Galichica Mountain, which is constructed mainly of carbonate karstfied formations, separates them. In the Tushemisht – Sveti Naum sector of Ohrid Lake, situated on both sites of Albanian – FYROM border, big springs issue that are supposed to be fed by Prespa Lake by the underground karst flow Environmental isotope data of Deuterium and 18O have been used to identify the origin of the recharge of Tushemisht springs situated in Albanian territory. The results of this study indicate that 52 % of the mean discharge of Tushemisht springs is recharged from Prespa Lake, and 48 % of their discharge is recharged from the infiltration of the precipitation in Mali Thate – Galichica Mountain.
