Summary
Built in 1983 by the US Army Corps of Engineers, this gravity dam stands at a structural height of 55 feet and has a hydraulic height of 48 feet. With a controlled spillway width of 495 feet, the dam has a maximum discharge capacity of 204,300 cubic feet per second, making it a crucial component for managing water levels in the area.
This significant dam has a very high hazard potential, as noted by the risk assessment rating of 1. The US Army Corps of Engineers actively manages flood risks associated with the dam by continuously monitoring its condition, prioritizing necessary actions, and collaborating with local emergency managers to ensure preparedness in case of a dam-related emergency. An Emergency Action Plan (EAP) has been prepared and updated regularly, with inundation maps in place to mitigate risks. The dam plays a crucial role in water resource management and flood control efforts in the region, highlighting the importance of ongoing maintenance and risk management measures.
As climate change brings unpredictable weather patterns and increased water flow, the Glover Wilkins Lock and Dam - Spillway serves as a critical infrastructure for maintaining water levels and protecting downstream areas. With its strategic location and functionality, the dam exemplifies the dedication of the US Army Corps of Engineers in safeguarding communities and water resources against potential hazards. Ongoing efforts to enhance risk management strategies and emergency preparedness further demonstrate the commitment to ensuring the safety and resilience of the dam and surrounding areas.

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.
