Summary
This earth dam, standing at 12 feet tall and 180 feet long, impounds the Smith River to create Kilton Pond. With a storage capacity of 407 acre-feet and a surface area of 68 acres, the dam serves as a popular recreational spot for water resource and climate enthusiasts to enjoy activities such as fishing, boating, and wildlife viewing.
Managed by the New Hampshire Department of Environmental Services Dam Bureau, Kilton Pond Dam has a low hazard potential and is currently assessed to be in fair condition. The dam has a spillway width of 34 feet and a maximum discharge of 2,583 cubic feet per second. Despite its moderate risk assessment, the structure has not undergone any recent modifications and its emergency action plan status is unlisted. The last inspection in November 2016 determined that the dam meets state regulatory standards and is safe for public use, further solidifying its importance as a recreational resource in the region.
For water resource and climate enthusiasts, Kilton Pond Dam offers a unique opportunity to experience the intersection of human infrastructure and natural beauty. With its picturesque setting along the Smith River and ample recreational activities available, this state-regulated earth dam provides a valuable resource for both locals and visitors alike. As efforts continue to maintain and monitor its condition, Kilton Pond Dam remains a focal point for those interested in understanding the role of dams in managing water resources and adapting to changing climate 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.
