“I am devastated by this tragedy,” said Commissioner Dan Ryan, who oversees the bureau. “I know that the community and everyone within PP&R grieves as well.”

Parks director Adena Long said her staff will partner with other city officials “to participate in an investigation to see what we can learn from this tragic incident.”

The parks bureau’s “goal is to provide the safest environment possible for the community,” Long said.

No one has drowned at a Portland swimming pool since at least 1985, the parks bureau told The Oregonian/OregonLive last year.

Several children have survived close calls in more recent years, including a 13-year-old girl and 6-year-old boy at what was then Wilson pool in 2012 and 2002, respectively, and a 7-year-old boy at Peninsula Park pool in 2009.

Montavilla lifeguards had performed the third highest number of swimming rescues — 75 — among Portland’s 12 indoor and outdoor pools between 2017 and May 2022, a newsroom analysis found.

All of Portland’s outdoor pools closed for the season on Sunday, a week before Labor Day, the traditional end of summer.
