在北美,水库大都修建在湖泊稀少地区,主要分布于美国的中西部、东南部和西南部,例如,俄克拉何马州有67座平均面积超过200公顷的水库,总面积为139.2万公顷。而在明尼苏达只有12座大型水库,总面积为15.5万公顷。这些水库大都较浅且处于温暖气候地带,它们的地理分布与它们的生物学是相关的。这些水库的 In North America, reservoirs are mostly built in sparsely populated lakes, mainly in the Midwest, southeastern and southwestern parts of the United States. For example, Oklahoma has 67 reservoirs with an average area of ​​more than 200 hectares with a total area of ​​1,392,000 hectares. In Minnesota, there are only 12 large reservoirs with a total area of ​​155,000 hectares. These reservoirs are mostly shallow and in warm climates, and their geographical distribution is related to their biology. These reservoirs
