Summary
Built in 1959, this earth dam reaches a hydraulic height of 13 feet and a structural height of 16 feet, with a length of 275 feet. The dam provides a storage capacity of 100 acre-feet, supporting the irrigation needs of the surrounding area.
Despite its age, Hancock Lake Dam has been inspected for safety and remains in a significant hazard potential category. While not currently rated for condition, the dam has not undergone any modifications since its last inspection in 2003. With a normal storage capacity of 83 acre-feet and a drainage area of 5,907 acres, the dam plays a crucial role in managing water resources in the region.
Owned privately, Hancock Lake Dam serves as a reminder of the importance of maintaining and monitoring critical infrastructure for water management and climate resilience. As water resource and climate enthusiasts, understanding the role of dams like Hancock Lake in supporting irrigation and water supply is essential for sustainable development and environmental stewardship in the face of changing climate conditions.

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.
