Summary
Fish and Wildlife Service. Constructed in 1958, this Earth-type dam serves as a Fish and Wildlife Pond along Lake Creek. With a height of 11 feet and a length of 730 feet, the dam has a storage capacity of 70 acre-feet and a surface area of 6.4 acres. Despite its low hazard potential, the dam's condition assessment in 2016 was marked as poor, indicating a need for maintenance and rehabilitation to ensure its long-term functionality.
The dam features an uncontrolled spillway with a width of 306 feet and has a moderate risk assessment level. While it has not undergone any modifications since its completion, regular inspections are conducted every five years to assess its structural integrity and overall condition. The surrounding area, including the drainage area of 11.2 square miles, relies on the dam for water storage and wildlife habitat preservation. With its historical significance and ecological importance, Beaver Pond Dam serves as a vital resource for the local ecosystem and climate enthusiasts seeking to understand the intersection of water management and environmental conservation.

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.
