Summary
Built in 1976, this earth dam stands at a height of 27 feet and spans 290 feet in length, with a storage capacity of 81 acre-feet. The primary purpose of this dam is for fire protection, stock, or as a small fish pond.
With a low hazard potential and a moderate risk assessment rating, Adams-Tocks Pond Dam 1 has a controlled spillway type with a width of 40 feet and uncontrolled outlet gates. The dam's normal storage capacity is 55 acre-feet, serving a drainage area of 0.15 square miles. While the condition assessment is currently not available, the last inspection in September 2014 reported no significant issues.
Water resource and climate enthusiasts may find Adams-Tocks Pond Dam 1 to be an intriguing structure for its design features, purpose, and regulatory oversight. As a key component in the management of water resources in the area, this dam plays a vital role in providing necessary services while maintaining a relatively low risk profile. Further monitoring and assessments will be crucial to ensure the continued safety and functionality of this important infrastructure.

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.
