Information for boaters
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 details.
Other service updates (Updated 05 October 2022 at 1730)
Shiplake Lock - Shiplake's pump-out is out of service until further notice.
Sunbury Lock - The head gate on the towpath side does not fully open and care must be taken when entering and exiting the lock.
Hurley Lock - The public toilet facilities are currently unavaiable. Alternative toilets have been made available in Hurley Village car park. The closure is due to issues with safety accessing the toilet block.
Mapledurham Lock - The pump-out facilities are available during lock keepers hours. Tokens available from Whitchurch, Mapledurham and Caversham Locks.
Boulters Lock - The gates on the pedestal side open the majority of the way. Please be cautious when entering and exiting the lock.
Boveney Lock - The pump-out and Elsan facilities are out of service until further notice.
Marsh Head Horse Bridge - The towpath bridge upstream of Marsh Lock will be closed until further notice due to safety concerns. Our operational teams and framework specialists will be inspecting the bridge to determine necessary actions to safeguard bridge users. We apologise for any inconvenience this causes and will be working with the local authority to implement a footpath diversion as soon as possible.
Low flows and water safety
We are experiencing a period of drought. 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. Please comply with all instructions at lock sites.
Our water safety advice is available at Staying safe around water - GOV.UK (www.gov.uk)
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.

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.
