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.

15 feet
Dam height

Height of the dam is defined as the vertical distance between the lowest point on the crest of the dam and the lowest point in the original streambed.

15 feet
Structural height

Structural height of the dam is defined as the vertical distance from the lowest point of the excavated foundation to the top of the dam. Top of dam refers to the parapet wall and not the crest.

107,000 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.

1,200 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.

1,200 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.

85 acres
Surface area

Surface area, in acres, of the impoundment at its normal retention level.
