Summary
Built in 1957, this private-owned earth dam stands at a structural height of 19 feet with a hydraulic height of 14 feet. With a storage capacity of 150 acre-feet and a normal storage level of 132 acre-feet, the dam plays a crucial role in maintaining water resources in the area.
Despite being classified as having a low hazard potential and not being regulated by the state, Hamme Lake Dam is subject to regular inspections to ensure its structural integrity and safety. The last inspection took place in April 2002, with its condition rated as "Not Rated". With a maximum discharge capacity of 165 cubic feet per second, the dam provides a reliable source of water for the surrounding Gibbs Creek-Tr area.
Although not under the jurisdiction of state regulatory agencies, Hamme Lake Dam remains a significant feature in the local water infrastructure. Its role in water management and conservation underscores the importance of sustainable practices in maintaining climate resilience for the future.

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.
