Summary
This earth dam, with a height of 18 feet and a hydraulic height of 34.5 feet, provides a storage capacity of 458 acre-feet and covers a surface area of 23 acres. Despite being privately owned and not state regulated, the dam is inspected every 5 years to ensure its structural integrity.
With a low hazard potential and a moderate risk assessment, Hobby Lake Dam plays a crucial role in the local community's water resource management. While its spillway is uncontrolled and outlet gates are also uncontrolled, the dam has not been modified in recent years and its condition remains unrated. The surrounding area, including Turner County, benefits from the dam's water storage capacity and contributes to the region's climate resilience and sustainability efforts.
As a key feature in the water infrastructure of Turner County, Hobby Lake Dam stands as a testament to the importance of private ownership in maintaining critical water resources. Its strategic location and multi-purpose design make it a valuable asset for fire protection, stock management, and small fish pond operations. The dam's risk assessment and inspection frequency ensure the safety and functionality of the structure, highlighting the ongoing commitment to water resource management and climate adaptation in the region.

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.
