Summary
Built in 1998 by the USDA NRCS, this dam stands at a height of 27 feet and spans 420 feet in length. With a storage capacity of 112 acre-feet and serving a drainage area of 120.32 square miles, the primary purpose of this dam is flood risk reduction. The dam is situated on a tributary of East Locust Creek and is classified as having a low hazard potential.
Despite being unregulated by the state, East Locust Creek Watershed Dam E-18 plays a crucial role in managing flood risks in the area and providing additional benefits such as fire protection and wildlife habitat. With a moderate risk rating, this dam has not been formally assessed for its condition, but it has not shown any signs of distress. The dam features an uncontrolled spillway with a width of 40 feet and no outlet gates, ensuring that excess water can safely flow out during periods of high discharge. Overall, this dam serves as an essential infrastructure for the community of BIYNTON and contributes to the overall water resource management in the region.

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.
