Summary
This privately owned earth dam has a height of 13 feet and a length of 1100 feet, with a maximum storage capacity of 221 acre-feet. While the dam is primarily used for water supply, it also plays a role in flood control and irrigation in the area.
With a high hazard potential rating of 2, the Killam Lake No 1 Dam is closely monitored and inspected by the state regulatory agency. Despite not being state-regulated, the dam undergoes regular inspections and maintenance to ensure its structural integrity. The dam lacks a spillway and has no associated locks, indicating its design for water storage rather than navigation purposes.
While the dam's condition is currently not rated, its risk assessment is deemed high. The lack of an emergency action plan and inundation maps raises concerns about the potential consequences of a dam failure. As water resource and climate enthusiasts, it is important to recognize the significance of infrastructure like the Killam Lake No 1 Dam in sustaining water supply and managing risks associated with dam operations.

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.
