Summary
Built in 1919, this earth dam stands at a height of 12 feet with a hydraulic height of 9.2 feet. Its primary purpose is to provide water supply for irrigation and other uses, with a storage capacity of 185 acre-feet. The dam spans 475 feet in length and covers a surface area of 42 acres, with a drainage area of 2 square miles.
Although Enquist has a low hazard potential and is considered to be in satisfactory condition as of the last assessment in September 2017, it is subject to state regulation, inspection, and enforcement by the California Department of Water Resources (DWR) under the Safety of Dams program. The dam is situated on Tr Olivers Can, a river or stream, and falls under the jurisdiction of the Sacramento District of the US Army Corps of Engineers. In case of emergencies, an Emergency Action Plan (EAP) may be prepared to ensure the safety of the surrounding community.
Enthusiasts of water resources and climate will find Enquist an intriguing example of early 20th-century dam engineering in California. As a vital water supply and irrigation infrastructure, it highlights the importance of maintaining and regulating dams to mitigate risks and ensure water security for local communities. With its historical significance and continued operational relevance, Enquist serves as a reminder of the intricate relationship between human infrastructure, environmental stewardship, and sustainable water management in the face of changing climate conditions.

Dam Data Reference
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.
