Members of the South Cambs Turtles swimming team took the plunge at Royston Leisure Centre to raise money for families in need.
The team, which was made up of parish, district and county councillors and their families, swam in aid of Home-Start Royston, Buntingford and South Cambs.
Team captain Susan van de Ven, county councillor for Melbourn and Bassingbourn and district councillor for Bassingbourn and Litlington, said: "Home-Start provides support to young families, at a time of life that can be unexpected and overwhelming.
"I first became aware of Home-Start when our twins were born a few weeks early. We had moved to England and South Cambs not long before and had no family network to call on.

"Our health visitor put us in touch with Home-Start. Straight away a little bit of practical help made a huge difference in finding our way.
"It also taught me that it’s OK to ask!"
The fundraising page is open until the end of May. Search 'Home-Start Turtles Aquathon' to donate.
