Enquist is a privately owned dam located in Modoc, California, near the city of Goose Lake. 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.
