Cause
Water from the river broke through at a fault the workings had not found.
Contributing factors
The fault had not been found and, a coal owner told the Select Committee, had probably not been looked for.
What happened
The colliery lay on both sides of the Manchester, Bolton and Bury Canal near where the Croal meets the Irwell, and the geology of the valley made its pits prone to flooding. Robert Grundy, a Manchester coal owner, described the disaster to the Select Committee on Accidents in Mines that year.
