Summary
This private dam has a primary purpose of "Other" and is classified as an Earth dam with a structural height of 25 feet. With a storage capacity of 94 acre-feet and a drainage area of 30 square miles, the dam plays a crucial role in managing water flow in the TR-BIRKHEAD BR BOBS CR stream.
Despite its low hazard potential, Ross-Mulvehill Lake Dam has not been rated for its condition assessment. The dam has not undergone recent inspections, and its emergency action plan status is unknown. The dam's risk assessment, risk management measures, and inundation maps prepared are also not specified in the data. This lack of updated information highlights the importance of regular maintenance and monitoring of dam infrastructure to ensure public safety and water resource sustainability in the face of changing climate conditions.
While Ross-Mulvehill Lake Dam may not currently pose a significant risk, it is essential for stakeholders to prioritize the assessment and maintenance of this critical infrastructure. With its strategic location and role in water management, the dam's condition and emergency preparedness should be regularly evaluated to safeguard against potential hazards and ensure the long-term sustainability of water resources in the region. For water resource and climate enthusiasts, staying informed about the state of dams like Ross-Mulvehill Lake Dam is crucial for effective water resource management and climate adaptation efforts.

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.
