Summary
With a primary purpose of recreation, the dam also provides water supply for the area. Situated on Doctors Creek, this earth dam stands at a height of 18 feet and has a maximum storage capacity of 400 acre-feet.
Despite its age, Old Water Supply Lake Dam remains in significant condition and has a hazard potential that is rated as significant. The dam has not been inspected since 1995, but it is reassuring to note that it meets regulatory guidelines and has emergency action plans in place. With a surface area of 75 acres and a drainage area of 0.7 square miles, this dam plays a crucial role in managing water resources in Franklin County.
As water resource and climate enthusiasts, it is important to recognize the significance of infrastructure like Old Water Supply Lake Dam in ensuring the sustainability of our water supply. With its historical importance and continued relevance in the community, this dam serves as a reminder of the interconnectedness of water resources and the need for proper maintenance and oversight to mitigate potential risks.

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.
