10 injuries were recorded in the one month the flumes were open at the NSC in Douglas.
That's according to figures published in response to a freedom of information request to the Department of Education, Sport and Culture.
The flumes - which had been shut for more than three years for a multi-million pound revamp re-opened at the end of November last year.
However, by January 1 this year - one had closed.
Government said the closure followed concerns just before Christmas that 'the swimmer's exit from the flume wasn't always as smooth as it should be.'
A subsequent statement said the 'exact cause of the problem was yet to be established', but the observations of staff and users’ experience on the flume have been sent to the contractor that installed the facility.
According to officials - the contractor is due back in the Island early in the New Year, and has been asked to investigate and rectify the problem.
The other flume, splash zones and pools will remain open as normal.
