The classification of dams by size is as follows: The size classification is determined by either the maximum storage capacity or the height, whichever gives the larger size category.
SIZE | STORAGE CAPACITY | HEIGHT |

Small | 50 to 1000 | 25 to 40 |
Intermediate | 1001 to 50,000 | 41 to 100 |
Large | greater than 50,000 | greater than 100 |
