Summary
This earth dam stands at a height of 26 feet, with a structural height of 30 feet and a length of 520 feet. It has a storage capacity of 111 acre-feet and a drainage area of 140.16 square miles, making it a vital component in managing water resources in the region.
With a spillway width of 20 feet and a maximum discharge of 158 cubic feet per second, this dam plays a crucial role in mitigating potential flooding risks. Despite being classified as having a low hazard potential and not yet rated for condition assessment, the dam is strategically designed to safeguard the surrounding area from inundation. While it has not undergone recent inspections, the structure remains an essential asset in the overall water management system of the locality.
Managed by the local government and situated in a picturesque landscape, East Locust Creek Watershed Dam E-11 exemplifies the harmonious balance between environmental conservation and flood protection. As climate change continues to impact water resources, the presence of such infrastructure becomes increasingly crucial in safeguarding communities and ecosystems from potential risks. With its moderate risk assessment and design primarily focused on flood risk reduction, this dam stands as a testament to the proactive measures taken to address climate challenges 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.
