I am going to build a dam on my property. The dam will be located on a small creek bead. The creek bead is dry in the summer but in the winter it can flow a fair amount of water. When the dam is complete the resivor will be aprox 4 acres. The dam will be over 20'tall and 300' across . My question is how do I go about calculating the size for an emergncy spillway to be large enough to handle the largest storm the resivor could encounter.
