During a heatwave on August 5, 1917, two cousins, Robert Gisler’s daughter Elizabeth, 11, and Sam Gisler’s daughter Mabel, 10, went to the Santa Ana River with Elizabeth’s sister Lucile, 6, to play in the water.
The two older girls were wading in the shallows of the channel, laughing and playing, when they suddenly lost their footing and stepped into a large hole. They struggled to find a foothold in the deep drop-off, while their cries for help went unanswered. Young Lucile thought they were only playing.
When the girls disappeared under the water, Lucile ran for help, eventually finding a surf-fisherman on the beach 3/4 mile away. He and a 13-year-old boy managed to recover the girls, who by that point had been in the water between 45 minutes and an hour.
Every effort was made to revive them. An electric car was flagged down, and a Pulmotor resuscitator was sent from Santa Ana. But it was too late. At the time of the accident, Sam and Robert were in Seal Beach, where they received the sad news.
