Summary

Completed in 1998, this earth dam stands at 17 feet tall and serves primarily for irrigation purposes. With a storage capacity of 47 acre-feet and covering a surface area of 3.5 acres, Scotch Valley plays a crucial role in flood risk reduction and water resource management in the region.

Located in Frankstown Township along the TR New Creek, Scotch Valley is a significant structure with a hazard potential that is closely monitored through regular inspections. The dam has undergone modifications in 2006 to enhance its hydraulic capabilities, ensuring its effectiveness in mitigating potential risks. In case of emergencies, the dam's emergency action plan is yet to be prepared, highlighting the importance of proactive risk management and preparedness in safeguarding the surrounding community and environment.

As water resource and climate enthusiasts, understanding the vital role of structures like Scotch Valley in water management and conservation is essential. By recognizing the significance of dams like Scotch Valley in balancing irrigation needs, flood protection, and environmental sustainability, we can appreciate the intricate interplay between water resources, infrastructure, and climate resilience in ensuring a secure and sustainable future for all.

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.
