Information for boaters
Low flows and water safety
We are experiencing an extended period of very dry weather. We need your help to try and minimise the effects of this dry weather by making sure all locks are as full as possible when used to save water. Some parts of the upper Thames are already experiencing very low flows, especially in backwaters and tributaries. To try and maintain flows and levels as best we can, to protect wildlife, reduce more serious impacts for navigation and maintain levels for public water supply, we may need to close locks outside of normal lock-keeper hours of duty. This could affect any of our sites along the length of the Thames. Should that be necessary, we will let you know at the earliest possible opportunity.
During periods of hot weather we see an increase in the number of people swimming in the river, including near vessels, and even jumping off bridges. Please be aware of this. We are working with partners to limit and prevent this. Our water safety advice is available at Staying safe around water - GOV.UK (www.gov.uk)
Coronavirus information
Please find the latest guidance for all boaters on Environment Agency managed waterways here: Environment Agency waterways: Coronavirus (COVID-19) updates.
Lock keepers’ hours of duty
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.
Our Lock Service Rota can be found here: River Thames: lock keeper service.
- 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 except at Teddington Lock and the beam locks upstream of Oxford, 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.
The levels of service will be reviewed regularly. Our staffing levels are currently reduced as a result of coronavirus and long term sickness absence.

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 shoals and tree debris collecting and some shallows forming.
24hr and Lock Moorings
Transiant moorings are now managed by Environment Agency Lock and Weir Keepers. Notices are posted on sites and boaters should report to lock keeper on arrival to report their stay.
