Summary
Constructed in 1962 by Easton Utilities Com., this earth dam structure stands at a height of 15 feet and spans 4800 feet in length, offering a storage capacity of 388 acre-feet. The lagoon has a low hazard potential and has not been rated for its condition, but it is regularly inspected and regulated by the Maryland Dam Safety agency.
Situated near the Choptank River in Lloyds Landing, Easton Primary Sewage Lagoon plays a vital role in managing drainage and maintaining a controlled spillway system with a maximum discharge capacity of 20 cubic feet per second. Despite its critical function, the lagoon's risk assessment indicates a very high risk level, emphasizing the need for effective risk management measures to ensure its structural integrity and environmental impact mitigation. While the dam has not been modified in recent years, its emergency action plan status and inundation mapping readiness remain unspecified.
With a surface area of 45 acres and a normal storage capacity of 144 acre-feet, Easton Primary Sewage Lagoon serves as a key resource for water management in the region. Governed by local regulators and regularly inspected for compliance with state regulations, this vital infrastructure plays a significant role in supporting the local ecosystem and protecting water resources in the surrounding area. Despite its age, the lagoon continues to play a crucial role in water resource management and environmental conservation efforts in Talbot County.

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.
