## Facts

- East Contra Costa Irrigation Company owned and operated a main irrigation canal that crossed Marsh Creek through a constructed syphon that carried canal water beneath the creek and back into the canal.
- The syphon entrance at the canal end was about four feet in diameter, unguarded, and lacked warning signs.
- The company built and maintained employee houses near the canal; the access road ran alongside the canal and Marsh Creek, separated from the canal only by a low concrete bulkhead.
- Arturo Sanchez, a company employee living in this housing, had a five-year-old son who played near the canal with other children.
- The canal contained about three feet of muddy water, which concealed the syphon entrance below the surface.
- The child fell into the canal while trying to wet a handkerchief and was drawn into the syphon; his body was recovered about fifteen feet inside.
- Sanchez sued for wrongful death, alleging negligent maintenance of a concealed, unguarded, and unmarked dangerous condition near residences and a roadway.

## Issues

1. Whether an irrigation company that owes no general duty to guard an ordinary open canal against children may be liable when it maintains a concealed, artificial danger (an unguarded syphon intake) near residences where children are foreseeably present.
2. Whether the concealed syphon intake constituted a trap or hidden peril imposing a duty to guard the condition or provide adequate warning.

## Decision

- The California Supreme Court affirmed the plaintiff’s $6,000 judgment.
- The court held that the general rule relieving canal owners from a duty to fence or guard open waterways did not control because the injury resulted from a concealed, artificial, and highly dangerous condition.
- Given the company’s placement of employee housing near the canal and the foreseeability of children in the area, the company owed a duty to use reasonable care to protect against or warn of the concealed syphon hazard.

## Legal Principles

- A landowner is not generally required to child-proof an ordinary open canal or other obvious body of water merely because children might drown.
- When a landowner creates or maintains a concealed, artificial, and unusually dangerous condition associated with a waterway, the landowner must exercise reasonable care to protect foreseeable victims, including children.
- Foreseeability is heightened where the landowner places residences or other invitees in close proximity to the concealed hazard and knows children are likely to be present.
- A hidden mechanism or condition that is not apparent to a child and creates an extraordinary risk may be treated as a trap, supporting liability for failure to guard or warn.

## Conclusion

The court upheld liability because the child’s death was not caused by the ordinary risk of open water, but by an unguarded syphon intake concealed under muddy water in an area where the defendant placed employee families and could foresee children’s presence, creating a duty to guard or warn against the hidden danger.
