They are the 22 pupils on a camping trip who fell into Sungai Kampar when the suspension bridge they were crossing broke near Kuala Dipang, Kampar, at about 10pm on Monday.
The dead girl was identified as Dina Deve Nathan, 11, from SK Tamil Mambang Diawan. Rescuers found her at Kampung Pasir, about 2km downstream from the broken bridge, at about 8.40am Tuesday. Her body was sent to the Kampar Hospital.
Police said twenty other pupils, who were not on the bridge, escaped unscathed.
According to one of the survivors, Mohd Azid Teng, 12, from SKJC Bemban near Kampar, the pupils had had supper at SK Kuala Dipang and were crossing the bridge to get to the camping site when a few of the pupils started jumping and shaking the bridge.
The bridge then gave way and he found himself falling into the river along with the other screaming pupils.
Fortunately, he fell into shallow waters and waded out.
They were among 298 students from 60 primary schools from Kampar, Tronoh and Batu Gajah who were attending a co-curriculum activity organised by the Kinta Selatan district education office.
Search and rescue is ongoing.
