西湖水库

西湖水库,位于内蒙古自治区通辽市奈曼旗,现已干涸。

简介

西湖水库位于科尔沁沙地中的奈曼旗大沁他拉镇西北约5公里处。地理坐标为北纬42°51′至42°53′,东经120°31′20″至120°36′12″。原为一天然泡子,形成于元朝。1962年,在工程庙泡子的基础上,为拦蓄孟可河、荷叶乌丹以下区间洪水并作为舍力虎水库的泄洪区,发展渔业,保护下游奈曼旗人民政府所在地,建成西湖水库。西湖水库南北最宽处约10公里,东西长15公里,水库平面呈瘦椭圆状。水库面积25平方公里,设计总库容5120万立方米。西湖水库水草丰美,特产鲤鱼,鸥鸟纷飞。后来,因为教来河、孟可河长年断水,加上水库渗漏、蒸发,水库水位自1995年起开始下降,于2001年5月完全干涸。此后,湖心开荒种地,湖区风沙强烈。西湖水库干枯后10年的年降水量减少率18.1%,年大雨日数减少率18%。[1][2]
