Summary
Managed by the Pennsylvania Department of Environmental Protection, this earth dam serves primarily for irrigation purposes along the TR Coal Lick Run river. With a height of 14 feet and a length of 300 feet, Rohanna has a storage capacity of 33.6 acre-feet and a drainage area of 0.89 square miles.
Despite being classified as having a significant hazard potential, Rohanna is currently in fair condition as per its last inspection in November 2017. The dam has a scheduled inspection frequency of every two years to ensure its structural integrity and safety. While no emergency action plan or risk assessment has been reported to date, the dam remains under the jurisdiction and regulatory oversight of the state of Pennsylvania.
Enthusiasts of water resources and climate will find Rohanna to be an intriguing case study in the management of private dams for agricultural purposes. With its location in a rural area and its vital role in providing irrigation water, Rohanna showcases the intersection of human infrastructure with natural water systems. Monitoring its condition and hazard potential will be crucial for ensuring the safety of surrounding communities and the sustainability of water resources in the region.

Dam Data Reference
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.
