SPORTS clubs have to find a new home after a decision to close the National Water Sports Centre's sports hall.
The centre's new managers, Serco Leisure, have informed users of the hall that it will be closing at the end of July.
It is planned for the hall to be turned into offices as part of a wider multi-million pound redevelopment of the centre.
But club leaders say the decision could affect the teaching of grassroots sport in the area.
Rob Manning has held training sessions for South Notts Shotokan Karate Club at the sports hall for the last decade.
It currently has around 60 members.
He said: "The upshot of it all is the changes are involving some casualties, and they are grassroots sports clubs."
Notts County Council struck a deal in January with Serco Leisure to redevelop and run the site. The company took over managing and maintaining the centre in April and is planning a £6.7m redevelopment over the next 21 years.
It includes a £1.6 million contribution from the council.
New features planned include an outdoor laser tag game, Segway scooter hire and state-of-the-art gym facilities.
The 2,000 metre regatta lake, and slalom and rafting course, will be retained, while improved catering and conferencing facilities are planned.
Mr Manning said he is searching for a new home for his group, which he has run for 28 years. "We are trying to enhance the characters of youngsters and people of all ages. That is being sacrificed," he said..
Brian Taylor, chair of the Holme Pierrepont Leisure Trust, which operates the National Water Sports Centre, said: "We are committed to protecting and enhancing the National Water Sports Centre's superb facilities for both top athletes and the local community.
"While this is great news for the site and the region, unfortunately it also means that the small number of clubs who currently use the sports hall will need to find a new venue from August. Our management team has been in close contact with the affected clubs to provide advance warning of the change as well as help them find alternative accommodation locally."
