Summary
With a structural height of 21.5 feet and a length of 450 feet, this lagoon has a storage capacity of 40 acre-feet and a surface area of 5 acres. Despite not being regulated by the state, it is subjected to inspections to ensure safety.
The dam at Hollow Farm Lagoon poses a significant hazard potential, although its condition has not been formally rated. The last inspection was conducted in April 2003, highlighting the need for regular monitoring and maintenance. The dam does not have an Emergency Action Plan prepared, raising concerns about its preparedness in case of emergencies.
For water resource and climate enthusiasts, Hollow Farm Lagoon serves as a crucial case study for understanding the management of private earth dam structures. The dam's location on the Devils Cradle river and its significant hazard potential underscore the importance of monitoring and maintaining such structures to mitigate risks and ensure environmental safety. Ongoing inspections and potential improvements in emergency preparedness are essential to safeguard the surrounding area and water resources.

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.
