云洲水库坐落在河北省赤城县县城以北20公里处。是北京白河上游两支流间筑坝形成的,水库呈V形,四面环山。水面面积略比十三陵水库大些,深浅不一,水草较少。其东南面紧邻公路(石子路),有漫坡,钓者多在此安营扎寨。因地处偏僻,故钓者较少,且多是当地爱好者。水库形成年代不详,但库中鱼类较多,而且没有污染。但不知何故,库中多是鲤鱼和白条,没见过大众 Cloud Island Reservoir is located in Chicheng County, Hebei Province, 20 kilometers north of the county. It is formed by dam formation between the two streams in the upper reaches of Beijing’s Baihe River. The reservoir is V-shaped and surrounded by mountains. Water area slightly larger than the Ming Tombs Reservoir, varying shades, less water plants.
