Lake Rooty Dam Reservoir Report
Nearby: Cox Road Dam Echo Dam
Last Updated: February 23, 2026
Lake Rooty Dam, also known as the Lower Dam at Innsbrook, is a private-owned structure located in Henrico, Virginia.
Summary
The dam is regulated by the Department of Conservation and Recreation and is subject to state permitting, inspection, and enforcement. Standing at a height of 22 feet with a length of 540 feet, the Earth-type dam controls Rooty Branch and provides a storage capacity of 142 acre-feet. Despite being classified as having a high hazard potential, the dam is currently in fair condition as of its last assessment in February 2018.
Given its strategic location and crucial role in water resource management, Lake Rooty Dam holds significant importance for the local community and the environment. The dam's primary purpose, along with its associated structures, contributes to flood control, water supply, and recreational opportunities in the area. With the dam being regulated by state agencies and inspected regularly, efforts are in place to ensure the safety and integrity of the structure. Climate and water resource enthusiasts will find Lake Rooty Dam to be a fascinating example of how human-made structures can harmonize with natural water systems to serve multiple purposes while maintaining environmental sustainability.

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.
