Open Water Swimming

2021 Open Water Swimming Sessions from May*

*dependent on water temperature being above 11 degrees Celsius, Covid restrictions and water quality testing.

We are hoping that we can return to swimming at Barton Marina from 1st May!

This is, of course, dependent on restrictions on Open air events being lifted (and remaining lifted) after 12th April.

Water Quality Report August 2020

Swimming at Barton is open to both club members and non-members but ALL swimmers must have read the Code of Conduct and hand in a signed copy of the Open Water Declaration form the first time they swim.

You can download the forms below.  Please print them off and bring them along to your first session.  There will be copies available at each session but completing them in advance will save you time.

No swimming is allowed outside of the Club sessions without the consent of the Site Owner.

Session Times

Wednesday 17:50-19:30

Saturday 08:00-10:30


Barton Marina, Barton Turn, Barton-Under-Needwood, Staffordshire, DE13 8DZ

Click here for map or scroll to bottom of the page.

As you enter Barton Marina the small lake is immediately on the right accessed through the small car park. From the car park keep the lake on you right and follow the path round to find the OW registration and water entry and exit point.

Click here for Water Quality Report.  Link disabled until April when we have tested the water quality.


Parking is free on the Barton Marina site.

The best place to park is in the small car park next to the lake but this can get very busy so the larger car park adjacent to the Marina complex can be used.

If you have bikes on the roof of the car please note there is a height restriction on the entry to the small car park.

The Lake

We swim in the small lake at Barton Marina.  The lake is clean and calm and follows a 500m buoy marked course anticlockwise around the island.  The lake is shallow around the edges although deeper by the island.  If necessary the water can be exited  from most of the shoreline and is therefore ideal for novice OW swimmers. Safety cover is provided on both sides of the lake.

Site Facilities

There are no changing facilities at Barton Marina. If you get changed by your car please respect that this site is open to the general public.

There are some toilets available for public use at the far end of the Marina Complex.


£5 (members and non-members)

Food & Drink

Within the Marina Complex there are several places to eat and drink.  For more information please visit the Marina website.

Safety Marshals

For every session we need a minimum of two marshals.

One of these will act as the Water Safety Officer to check people in and out of the water, and the other will need to be located on the other side of the island and act as Safety Marshal.

Marshaling is split into two shifts per session, the first shift includes set-up time and second shift includes packing away:

  • Wednesday 17:35-18:40 and 18:40-19:30
  • Saturday 07:45-09:15 and 09:15-10:30

Club members who are able to help out with OW Safety please sign up via the website – click here.

For any non-members who would like to help out please email

Coached Sessions

We have not yet made a decision on whether we will be operating open water coached sessions in 2021.
