Summary

Designed by USDA NRCS and completed in 1999, this earth dam stands at a height of 23 feet and spans 540 feet in length, with a max storage capacity of 65 acre-feet. Despite its low hazard potential, the dam plays a crucial role in managing water flow and protecting the surrounding area from potential flooding events.

With a drainage area of 160 square miles and a normal storage capacity of 25 acre-feet, this dam is a key component in the overall water resource management strategy for the region. Although not state-regulated, the dam's design and construction were overseen by the Natural Resources Conservation Service, ensuring its structural integrity and effectiveness in flood control. The dam's spillway, with a width of 30 feet, helps manage excess water flow during peak discharge events, safeguarding downstream communities and infrastructure.

Even though East Locust Creek Watershed Dam E-60 has not been rated for its condition assessment, its risk assessment is moderate, indicating the need for ongoing monitoring and maintenance. The dam's emergency action plan status and risk management measures are currently not available, highlighting the potential for further improvements in disaster preparedness. As a critical piece of infrastructure in the area, this dam serves as a valuable asset for water resource and climate enthusiasts interested in sustainable flood risk reduction practices.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
