Summary
Built in 1963 by the USDA NRCS, this earth dam stands at a height of 32.4 feet and serves the primary purpose of flood risk reduction along the Hubbard Creek. With a storage capacity of 1663.8 acre-feet and a drainage area of 3.26 square miles, this dam plays a crucial role in managing water resources in the region.
Despite its satisfactory condition assessment as of January 2016, Hubbard Murphee Structure Y-17a-73 Dam is classified as having a high hazard potential. This designation underscores the importance of regular inspections, which take place every five years, to ensure the structural integrity of the dam. The risk assessment for this dam is rated as moderate, indicating a need for ongoing risk management measures to prevent potential disasters and protect the surrounding communities.
With a history of serving as a vital tool for flood risk reduction in the area, Hubbard Murphee Structure Y-17a-73 Dam stands as a testament to the importance of sustainable water resource management in the face of changing climate patterns. As enthusiasts of water resources and climate resilience, it is crucial to monitor and support structures like this dam to safeguard communities and ecosystems from the impacts of extreme weather events.

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.
