Summary
This earth dam, completed in 1978 by the USDA NRCS, stands at a height of 24 feet and serves the primary purpose of flood risk reduction. With a storage capacity of 342 acre-feet and a drainage area of 0.6 square miles, the dam plays a crucial role in managing water levels during periods of high discharge.
Managed by the Pennsylvania Department of Environmental Protection, Thomas Creek is regulated, inspected, and enforced to ensure its structural integrity and functionality. Despite its high hazard potential, the condition assessment of the dam is reported as satisfactory, offering reassurance to local communities. The dam's location near Thomas Pond and its association with the Baltimore District emphasize its significance in safeguarding the surrounding environment and residents from potential flooding events.
As a key feature in the water management infrastructure, Thomas Creek (Rc & D-105) represents a proactive approach to mitigating flood risks in the region. With regular inspections and a history of effective flood risk reduction, this earth dam serves as a critical asset in preserving the safety and well-being of the local community and surrounding environment. Its strategic design and maintenance by the USDA NRCS highlight the importance of sustainable water resource management practices in addressing the challenges of climate change and ensuring the resilience of water infrastructure.

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.
