Plaintiff had a verdict for $8,500 in damages for the death by drowning of his son in an artificial reservoir maintained by the city and county in the area of Golden Gate Park. This reservoir was located on Strawberry Hill which is an island-lilce body of land in the middle of Stow Lake. It was designed to provide an artificial waterfall for the pleasure of the public on Sundays *702 and holidays and also for purposes of irrigating some of the lower areas. It was completely surrounded by a 4% or 5-foot picket fence in good condition. At one end two pipes or cement openings werе maintained—one for pumping water into the reservoir and one for drawing it out. From the pipe or hood through which the water was spilled intо the reservoir ran a cement spillway at a steep slant into the body of the reservoir. On the day of the accident this spillway had become slippery from moss and water.
Plaintiff’s son was 7 years old. He was playing about the reservoir with another boy of about the same age. When they decided to get a drink of water out of the pipe where the water was thrown upon the spillway they climbed over the picket fence and descended the side of the reservoir. The deceased went first and, while trying to drink out of the pipe, lost his footing and slipped into the water. His companion tried to rescue him but he also slipped on the mossy spillway and both boys were drowned.
Over defendant’s objection the plaintiff was permitted to show that an 8-year-old boy was drowned in the same reservoir about one year previous to this incidеnt. The defendant objected to this evidence on the ground that the Public Liability Act of 1923 (now Gov. Code, § 53051) was not involved. Objection is now made to thе admission of this evidence and to the instruction applying the .statute. Plaintiff put his case mainly on the attractive nuisance doctrine and thе trial court submitted that issue to the jury on instructions tendered by plaintiff. The defendant on this appeal makes the contention that the attractive nuisance doctrine was not applicable under the facts as a matter of law.

*703
App. 624, 634 [
Respondеnt’s effort to distinguish these cases on the basis of the “hidden or concealed” danger theory is not effective. It is a matter of common knоwledge among children and adults that wet concrete is slippery and that, when on a slanting incline as is so prevalent on the streets and sidewalks of San Francisco, it does not provide a safe footing. In surrounding the reservoir by a substantial fence the city gave to all persоns young and old sufficient notice that this reservoir was not a place of public recreation and that it was certainly not a place which the public could use for drinking water. The so-called hidden danger in the concrete intake was to the contrary a natural contrivance for carrying the water into the lake, and, when used as a footpath, was an open and obvious source of danger.
Appellant also contends that it was error to submit to the
*704
jury the question of the liability of the city under the Public Liability Act. A persuasive argument is made that such act applies only when the injured party was using the publiс property, or facility, in the ordinary and usual manner for which the property was maintained. Respondent relies on the opinion of thе Supreme Court in
Gibson
v.
County of Mendocino,
The applicable rule is well stated in
Beeson
v.
City of Los Angeles,
A different question arises when public property is being used by a trespasser for a forbidden private purpose. Thus, if an adult finds a reservоir completely surrounded by a protecting fence as a warning to all to keep out but he, in disregard of the warning, scales the fencе and enters the reservoir to take a swim, or to try for fish, he is making use of the reservoir for a use for which it was not maintained by the public. In such a сase it would seem clear that he would not come under the terms of the Public Liability Act.
Judgment reversed.
Goodell, J., and Patterson, J. pro tern., concurred.
A petition for a rehearing was denied February 15, 1952, and respondent’s petition for a hearing by the Supreme Court was denied March 13, 1952. Gibson, C. J., and Carter, J., were of the opinion that the petition should be granted.
