Summary

Owned privately, this earth dam stands at a structural height of 20 feet, offering a storage capacity of 66 acre-feet. Despite being non-regulated by the state, the dam is inspected regularly to ensure its safety and integrity.

The significant hazard potential of Glaxo Dam underscores its importance in mitigating flood risks in the area. While its condition assessment remains unrated, the dam's emergency action plan was last revised in 2015, indicating a commitment to preparedness. With no associated structures, this dam primarily focuses on its flood risk reduction purpose, reflecting its crucial role in protecting the surrounding community.

As water resource and climate enthusiasts, the data on Glaxo Dam provides valuable insights into its design, purpose, and storage capacity. The dam's location, ownership, and hazard potential highlight its importance in managing flood risks along the Northeast Creek. By prioritizing regular inspections and emergency preparedness, Glaxo Dam plays a vital role in safeguarding the community and the environment from potential flooding events.

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.
