∙ 9y agoOne use of a dam is to hold back water and control the flow so that lands downstream do not become flooded. A misuse of a dam would be to open the floodgates too wide so that lands are flooded. Another misuse of a dam might be blocking water flow by a landowner that does not want water to flow downstream.
