Summary
Constructed in 1994 by the USDA NRCS, this earth dam stands at a height of 27.8 feet, with a hydraulic height of 27 feet and a structural height of 31 feet. With a storage capacity of 84 acre-feet and a drainage area of 192 square miles, the dam plays a significant role in managing water flow and protecting the surrounding areas from potential flooding.
The dam features an uncontrolled spillway with a width of 20 feet and is primarily built with stone core and soil foundation. Despite being classified as having a low hazard potential, its risk assessment remains moderate. The condition assessment is currently not rated, highlighting the need for regular inspections and maintenance to ensure its effectiveness in flood control. Although the dam does not have outlet gates, its design and purpose underscore the importance of water resource management in mitigating climate-related risks in the region.
East Locust Creek Watershed Dam E-74 is a testament to the collaborative efforts of local government and the Natural Resources Conservation Service in safeguarding the community against floods. As water resource and climate enthusiasts monitor its condition and risk management measures, the dam continues to stand as a vital infrastructure for flood risk reduction in the area. Its strategic location and design highlight the importance of sustainable water management practices in ensuring the resilience of communities against changing climate patterns.

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.
