The council has revealed a soon-to-be scrapped underwater dive unit was forecast to cost more than £100,000 this year.
Norfolk Fire and Rescue Service confirmed last month that its underwater search and recovery team is to close after funding was cut.
Set up in 2012, the unit helped police in the recovery of evidence from water.
But fire service union representatives labelled the scheme as a 'vanity project', adding that the money could have been spent elsewhere.
In the past two years, the unit was called out just 16 times.
Latest figures from Norfolk County Council show it was forecast to cost £102,000 in 2016/17. Meanwhile, the income was forecast to be £24,000.
The county's chief fire officer David Ashworth said the team will close in the spring following a reduction in the National Resilience grant.
