Summary
This privately-owned dam has a primary purpose of providing essential services while also offering recreational opportunities. With a structural height of 18 feet and a hydraulic height of 14 feet, the dam spans 575 feet in length and has a maximum storage capacity of 88 acre-feet.
The dam, situated on Moro Creek-OS, has a low hazard potential and is currently rated as "Not Rated" in terms of its condition assessment. Despite not being regulated by the state, Harrell Lake Dam remains an important asset for water resource management in the area. With a surface area of 8.5 acres and a drainage area of 0.15 square miles, the dam plays a crucial role in managing water flow and providing recreational opportunities for the community.
Even though the dam has not been inspected recently and lacks certain emergency preparedness measures, it continues to fulfill its purpose effectively. Harrell Lake Dam stands as a testament to the importance of maintaining and managing water resources in a sustainable manner, especially in the face of changing climate conditions. For water resource and climate enthusiasts, this dam serves as a valuable case study in the intersection of human infrastructure and environmental stewardship.

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.
