Summary

Built in 1930, this earth dam stands at 15 feet high and spans 200 feet in length, serving primarily for hydroelectric and water supply purposes. With a storage capacity of 7,339 acre-feet and a surface area of 340 acres, this dam plays a crucial role in managing water resources in the region.

Managed by the Federal Energy Regulatory Commission, Moshier South Dike has a low hazard potential but is considered to have a high risk level. While information on its condition assessment is not available, regular inspections are conducted to ensure its safety. Despite not having a spillway, this dam remains a key structure for water management and energy production in Herkimer County, New York.

For water resource and climate enthusiasts, Moshier South Dike represents a fascinating example of early 20th-century engineering for harnessing hydroelectric power and ensuring water supply in the region. As part of the larger water infrastructure network in New York, this dam serves as a reminder of the importance of maintaining and monitoring such structures to mitigate risks and ensure sustainable water management practices for the future.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
