Summary
Standing at a height of 30 feet, the dam was completed in 1965 and has a storage capacity of 80 acre-feet. With a normal storage capacity of 44 acre-feet, the dam sits on the TR Charrette Creek and covers a surface area of 5 acres within a drainage area of 35 square miles.
Despite being privately owned, Siegmund Lake Dam has a high hazard potential and is classified as not rated in terms of condition assessment. The last inspection of the dam was conducted in December 1980, with no recent updates on its emergency action plan or risk assessment. The dam does not fall under state regulation or inspection, raising concerns about its maintenance and safety standards in the face of potential climate-related challenges.
For water resource and climate enthusiasts, Siegmund Lake Dam presents an intriguing case study of a privately owned recreational structure with significant storage capacity but limited oversight and maintenance. With its proximity to TR Charrette Creek and the potential risks posed by its high hazard potential, the dam serves as a reminder of the importance of proactive monitoring and management of water infrastructure in the face of changing environmental conditions.

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.
