Summary
Completed in 1994, this earth dam stands at a height of 26.5 feet and has a maximum storage capacity of 52 acre-feet. With a drainage area of 172.8 square miles, the dam plays a crucial role in managing water flow and reducing the risk of flooding in the region.
Despite being classified as having a low hazard potential, East Locust Creek Watershed Dam E-27 is considered to have a moderate risk level, indicating the importance of ongoing monitoring and maintenance. The dam features an uncontrolled spillway with a width of 20 feet and is primarily used for flood risk reduction. With a structural height of 34 feet and a normal storage capacity of 16 acre-feet, the dam serves as a key infrastructure for water resource management in the area.
Owned by the local government and operated by the Natural Resources Conservation Service, East Locust Creek Watershed Dam E-27 exemplifies collaborative efforts to safeguard communities from the impacts of extreme weather events. Its strategic location and design, coupled with regular risk assessments, ensure that the dam continues to fulfill its purpose effectively. For water resource and climate enthusiasts, this dam serves as a beacon of resilience and preparedness in the face of environmental challenges.

Dam Data Reference
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.
