Dam length

Length of the dam is defined as the length along the top of the dam. This also includes the spillway, powerplant, navigation lock, fish pass, etc., where these form part of the length of the dam. If detached from the dam, these structures should not be included.

12 feet
Hydraulic height

Hydraulic height of the dam is defined as the vertical difference between the maximum design water level and the lowest point in the original streambed.

203 cubic feet per second
Max discharge

Number of cubic feet per second the spillway is capable of discharging when the reservoir is at its maximum designed water surface elevation.

263 acre feet
Max storage

Maximum storage is defined as the total storage space in a reservoir below the maximum attainable water surface elevation, including any surcharge storage.

205 acre feet
Normal storage

Normal storage is defined as the total storage space in a reservoir below the normal retention level, including dead and inactive storage and excluding any flood control or surcharge storage. For normally dry flood control dams, the normal storage will be a zero value.
