Summary

Completed in 1973, this dam stands at a height of 120 feet and has a length of 3840 feet, with a storage capacity of 1300 acre-feet. The dam is situated on Dry Run, within the Washington County of Pennsylvania, and is regulated by the Pennsylvania Department of Environmental Protection.

Despite its satisfactory condition assessment, Maple Creek Slurry Pond 1 poses a high hazard potential due to its location and design. The dam has a drainage area of 0.2 square miles and covers a surface area of 60 acres. Although it has not been modified in recent years, regular inspections are conducted to ensure its structural integrity and compliance with state regulations. The emergency action plan for this dam is yet to be prepared, indicating a potential area for improvement in risk management measures.

With its impressive structure and significant storage capacity, Maple Creek Slurry Pond 1 serves as a vital component of the local water resource infrastructure. The dam's presence on Dry Run highlights its importance in managing water flow and storage in the region. As climate change continues to impact water resources, monitoring and maintaining structures like Maple Creek Slurry Pond 1 will be crucial to ensuring the safety and sustainability of water management systems in Pennsylvania.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
