Information for boaters
Coronavirus information
Please find the latest guidance for all boaters on Environment Agency managed waterways here: https://www.gov.uk/government/publications/environment-agency-waterways-coronavirus-covid-19-update.
In line with the current government Covid-19 restrictions we are taking the following approach to operating all of our lock and weir sites on the River Thames:
We aim to offer assisted passage to our boating customers during the boating season from 1 April to 30 September. We will also provide assisted passage during the Easter bank holiday weekend and spring and autumn half terms where these fall outside the season. Each lock will be manned by a resident, relief or seasonal Lock Keeper and/or volunteers, as appropriate and, wherever possible, to provide cover for staff breaks, weir work and maintenance. There may be occasions when we are unable to achieve this due to circumstances outside of our control such as staff illness.
Out of season between the 1 October and 31 March assisted passage may be available but cannot be guaranteed
Lock keepers’ hours of duty
- July and August: 9am to 6:30pm
- May, June and September: 9am to 6pm
- April and October: 9am to 5pm
- November to March: 9:15am to 4pm
One hour lunch break taken between 1pm and 2pm when cover unavailable.
Public power to be provided at all locks where available when assisted passage is not being offered by a Lock Keeper or volunteer, unless we are unable to do so due to circumstances outside of our control such as power outage or breakdown.
All of our sites accept card payments only.
Teddington Lock also has special arrangements in place. You can find more detail on our River Thames restrictions and closures page.
From 13 April until 17 May 2021
- Passage through Teddington Lock will be available from 6am to 10pm. Tidal transits and general assisted passage will be available between these times.
- Visiting licences will be available at the lock. Please follow social distancing guidance at the site when purchasing.
- As the self-service facility is not possible at Teddington, transit will not be possible through the night and from 10pm until 6am, the lock will be closed to traffic.
From 18 May
- Full 24 hour service will resume including purchasing of licences and journey advice by calling 020 8940 8723.
The levels of service will be reviewed regularly. Our staffing levels are currently reduced as a result of coronavirus.
Service announcements:
Some of our services are restricted due to the impact of the coronavirus (COVID-19) emergency. Go to locks and facilities for boaters for more detail.
- Culham Lock is open and operational. Please be careful when entering the Lock site and do not enter the fenced area.
- Mapledurham Lock sewage pump-out is unavailable.
- Iffley Lock - Hand wind only out of hours due to a fault with the public power.
- Cookham Lock electric charging point at the short stay moorings is unavailable. The next electric charging points are upstream Shiplake.
- Old Windsor electric charging point is currently unavailable.
Navigation Markers:
- When travelling upstream keep red obstruction marker buoys on your left, and green buoys on your right.
- When travelling downstream, keep red buoys on your right, and green buoys on your left.
- Single yellow marker buoys can be passed on either side.
In all cases, pass well clear of marker buoys, and take care. You should also be careful in the margins of the river, and around bends, where river and weather conditions have resulted in tree debris collecting and some shallows forming.
Key
- Caution strong stream
- We advise users of all boats not to navigate because the strong flows make it difficult and dangerous.
- Caution stream increasing
- We advise users of all unpowered boats not to navigate and users of powered boats to find a safe mooring. This is because river flows are likely to strengthen and red boards could be displayed very soon and without warning.
- Caution stream decreasing
- We advise users of all unpowered boats not to navigate and users of powered boats to navigate with caution.
