Summary

This private earth dam on TR-ARMSTRONG CREEK stands at a height of 29 feet with a hydraulic height matching that figure. With a length of 1070 feet, the dam boasts a maximum storage capacity of 380 acre-feet, making it an essential water source for the region.

Over the years, Camp Hobilitzelle Lake Dam has undergone modifications in 1982 and 1987 to enhance its hydraulic and structural components. The dam features an uncontrolled spillway with a width of 38 feet and three uncontrolled outlet gates. Although it presents a moderate risk, with a hazard potential not available and a condition assessment not rated, the dam remains a key asset for recreation and water resource management in the area.

Despite being privately owned and not regulated by the state, Camp Hobilitzelle Lake Dam continues to provide vital services for the community, with a focus on recreation. Its historical significance and ongoing maintenance efforts make it a noteworthy structure for water resource and climate enthusiasts to monitor and appreciate.

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.
