Summary
Its primary purpose is flood risk reduction, featuring a controlled spillway with a width of 4 feet and a hydraulic height of 23 feet. The dam stands at 34 feet tall, with a length of 10630 feet and a storage capacity of 196,000 acre-feet.
With a hazard potential rated as low and a very high risk assessment score of 1, East Dike plays a crucial role in managing flood risk in the region. Despite not being state-regulated, the dam is under federal ownership and jurisdiction. Although its condition is currently not rated, the dam has been inspected at a frequency of 5 years, with the last inspection dating back to January 1, 1980.
For water resource and climate enthusiasts, East Dike offers a fascinating glimpse into the intricate network of infrastructure designed to protect communities from the impacts of flooding. Its strategic location and design elements, such as the valve outlet gates and stone core type, showcase the innovative engineering techniques utilized to mitigate flood risks in the area. As a key player in flood risk reduction, East Dike stands as a testament to the ongoing efforts to safeguard water resources and adapt to the challenges posed by a changing climate.

Condition Assessment
SatisfactoryNo existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
