Summary
Constructed in 1963 by the Natural Resources Conservation Service, this dam serves the primary purpose of flood risk reduction along Fourmile Creek. With a height of 39 feet and a length of 252 feet, the dam has a storage capacity of 402 acre-feet, providing protection to a drainage area of 981 acres.
Despite being classified as having a low hazard potential, Long Swamp Creek WS Str # 18 has a moderate risk assessment due to its age and the lack of recent condition assessments. The dam has not been rated for its current condition, and the last inspection conducted was in June 2016, with an inspection frequency of every 5 years. While the dam is currently listed as not having an Emergency Action Plan (EAP) in place, it is crucial for stakeholders to prioritize the implementation of risk management measures to ensure the safety and integrity of this structure in the face of potential climate change impacts.
As water resource and climate enthusiasts monitor Long Swamp Creek WS Str # 18, it is essential for state agencies and regulators to address the need for updated inspections and assessments to determine the dam's current condition and potential vulnerabilities. With its strategic location and critical role in flood risk reduction, proactive measures should be taken to mitigate any risks associated with this dam and ensure its continued effectiveness in protecting the surrounding community and ecosystem from the impacts of extreme weather events.

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.
