Summary

Situated on the Roanoke River-Tr, this earth dam has a hydraulic height of 17 feet and a structural height of 20 feet, with a maximum storage capacity of 115 acre-feet and a normal storage level of 95 acre-feet. The dam spans 200 feet in length and covers a surface area of 7 acres, providing a picturesque setting for water enthusiasts to enjoy various recreational activities.

Despite being privately owned, Morris Lake Dam is inspected by state authorities, with the last inspection conducted in June 1993, revealing a low hazard potential and a condition assessment of "Not Rated". While the dam does not fall under state jurisdiction or regulatory oversight, it operates with a commitment to safety and emergency preparedness. Although details on emergency action plans and risk assessments are not provided, the dam's maintenance and management are essential for ensuring the safety of surrounding communities and preserving the recreational value of the reservoir.

For water resource and climate enthusiasts, Morris Lake Dam serves as a fascinating case study of a privately owned structure that balances recreation and water supply needs. With its scenic location and modest storage capacity, this dam highlights the importance of proper monitoring and maintenance to mitigate risks and ensure the continued enjoyment of water-based activities in the area. As climate change impacts water resources, understanding the resilience of dams like Morris Lake Dam becomes increasingly crucial in safeguarding communities and ecosystems from potential hazards.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
