Summary
This private-owned Earth dam stands at a height of 15 feet and spans 1000 feet along Nanny Branch. With a storage capacity of 90 acre-feet, the dam serves as a vital resource for the local community. Despite being unregulated by the state, the dam undergoes regular inspections and maintenance to ensure its structural integrity and reliability.
The dam, with a hazard potential rated as "Not Available" and a risk assessment of "High (2)", is equipped with a single outlet gate and lacks a spillway. While the condition assessment is listed as "Not Rated", it is clear that the dam plays a crucial role in managing water resources in the region. The risk management measures and emergency preparedness plans for Highway Lake Dam are currently undocumented, highlighting the need for ongoing monitoring and coordination among stakeholders to mitigate potential hazards and safeguard water security in the area.
As water resource and climate enthusiasts, it is important for us to recognize the significance of infrastructure like Highway Lake Dam in ensuring water supply and sustainability. By staying informed about the condition and management of dams like this one, we can contribute to the responsible stewardship of our natural resources and the resilience of our communities in the face of changing environmental conditions.

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.
