Police-led searches have recommenced today (Thursday) and efforts are continuing in an effort to locate two missing people.
Of the six adults involved in the boat capsize, two people were removed from the water and taken to Derriford Hospital, Plymouth, for treatment. One person has since been discharged and one person remains in hospital in a critical condition.
Two other people were removed from the water and checked by ambulance teams before being discharged at the scene.
The lake will remain closed for public access for the foreseeable future and localised road closures remain in place at the activity centre to allow access for the relevant emergency services.
A police update on the latest situation is expected this lunchtime.
