Summary
Constructed in 1971, this private earth dam stands at a height of 25 feet and has a storage capacity of 134 acre-feet. With a normal storage of 27 acre-feet and a surface area of 10 acres, the dam plays a crucial role in managing water resources in the area.
Despite being categorized as having a low hazard potential, Pollock Lake Dam has not been rated for its condition assessment. With no state regulatory oversight, the dam has not been inspected or assessed in recent years. While it may not pose an immediate threat, the lack of maintenance and inspection raises concerns about its long-term reliability and safety. Water resource and climate enthusiasts in the area may want to advocate for increased oversight and monitoring of Pollock Lake Dam to ensure its continued functionality.
Overall, Pollock Lake Dam presents an intriguing case study for water resource and climate enthusiasts, highlighting the importance of proper maintenance and regulation for dams, especially those serving multiple purposes. As a privately owned structure without state jurisdiction, the dam's condition and safety standards remain uncertain. Advocating for regular inspections and potential upgrades could help mitigate risks and ensure the sustainability of water resources in the region.

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.
