Summary

With a height of 23 feet and a length of 230 feet, the dam has a storage capacity of 92.6 acre-feet and serves as an important resource for the local community. The dam is regulated by the NHDES DAM BUREAU and undergoes regular inspections to ensure its safety and functionality.

While the dam has a low hazard potential and is currently in satisfactory condition, a moderate risk assessment indicates the need for continued monitoring and risk management measures. The dam's spillway, with a width of 5 feet, is uncontrolled, allowing for a maximum discharge of 644 cubic feet per second. The surrounding area, including Mill Brook, benefits from the dam's presence, providing vital water resources for wildlife and mitigating the risk of flooding in the region.

Water resource and climate enthusiasts can appreciate Davison Wildlife Pond Dam for its role in fire protection, stock, and as a habitat for small fish. As part of the larger ecosystem in Sullivan County, New Hampshire, the dam contributes to the sustainable management of water resources and supports the diverse wildlife in the area. With its regulated status and regular inspections, the dam exemplifies responsible stewardship of water infrastructure in rural settings, showcasing the intersection of human development and environmental conservation.

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.
