Summary
Constructed in 1991 by the USDA NRCS, this earth dam stands at a height of 29 feet and spans 470 feet in length, serving primarily for flood risk reduction along the TR-East Locust Creek. With a storage capacity of 143 acre-feet and a drainage area of 259.84 square miles, the dam plays a key role in managing water flow and protecting the surrounding area from potential inundation.
The dam features an uncontrolled spillway with a width of 48 feet and has a low hazard potential, rated as "Not Rated" in terms of condition assessment. Despite not being state-regulated, the site is inspected at a frequency of 0, with the last inspection conducted in September 1991. While the emergency action plan status and risk assessment remain unclear, the structure is considered to have moderate risk management measures in place. With its strategic location and design, East Locust Creek Watershed Dam E-59 stands as an essential element in the region's water resource management and climate resilience efforts.

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.
