Summary
The dam, primarily owned by the local government, stands at a height of 67 feet and has a storage capacity of 860 acre-feet. Situated on Yankee Doodle Creek, the dam plays a vital role in providing water to the surrounding community, with a normal storage capacity of 686 acre-feet and a maximum discharge of 1370 cubic feet per second.
Despite its important role in water supply, Moulton Creek Dam #1 poses a high hazard potential and has been assessed to be in poor condition as of March 2021. The dam is subject to regular inspections, with the last inspection conducted in May 2020 and scheduled at a frequency of every 5 years. While the dam is state regulated and permitted, with enforcement and inspection measures in place, its condition and hazard potential highlight the need for ongoing monitoring and potential risk management measures to ensure the safety and stability of the structure and its surrounding area.
As water resource and climate enthusiasts, the data on Moulton Creek Dam #1 underscores the importance of maintaining and safeguarding critical infrastructure for water supply in the face of potential hazards and changing environmental conditions. The dam serves as a reminder of the essential role these structures play in supporting communities and the need for continued vigilance and investment in their upkeep to ensure the resilience and sustainability of water resources in the region.

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.
