Summary
Built in 1974, this earth dam stands at 21 feet high and spans 286 feet in length, with a primary purpose of recreation. With a storage capacity of 70 acre-feet and a drainage area of 0.85 square miles, Ross provides essential water resource management in the region.
Despite its fair condition assessment, Ross poses a significant hazard potential, requiring regular inspections and maintenance to ensure public safety. Owned privately, the dam falls under the regulatory jurisdiction of the Pennsylvania Department of Environmental Protection, which oversees permitting, inspection, and enforcement activities. With its recreational benefits and importance in water resource management, Ross serves as a vital structure in the Susquehanna County landscape.
As climate change continues to impact water resources, the maintenance and management of dams like Ross become increasingly crucial. By staying informed about the condition and regulatory oversight of structures like Ross, water resource and climate enthusiasts can advocate for sustainable practices and policies to safeguard these vital components of our natural environment.

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.
