Summary
Built in 1836, this Earth-type dam stands at a height of 15 feet and has a length of 830 feet, with a storage capacity of 3170 acre-feet. The dam serves multiple purposes including recreation and water resource management for the TR-CHENANGO RIVER, with a significant hazard potential and fair condition assessment.
Despite its age, Leland Pond Dam has undergone regular state inspections, with the last assessment conducted in March 2019. The dam's spillway type is classified as uncontrolled with a width of 10 feet, capable of handling a maximum discharge of 170 cfs. The surrounding area covers a surface area of 96 acres with a drainage area of 5.25 square miles, making it an essential component of the local water infrastructure.
With its historical significance and ongoing maintenance, Leland Pond Dam stands as a vital resource for the community, providing both recreational opportunities and critical water management functions. Enthusiasts of water resources and climate will appreciate the dam's role in balancing the needs of the TR-CHENANGO RIVER ecosystem while ensuring the safety and well-being of the surrounding area.

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.
