Overnight lock closures for water loss tests on the K&A

Increased pressures on the water resources of the canal network through climate change, tougher environmental legislation and increased usage are likely — and a Water Resources Plan for the Kennet & Avon Canal is being produced so that the demands of future canal use can be met. 

'Stilling tests' in the pounds have to be done to estimate losses in the canal and to do this locks have to be closed overnight.

Stilling Tests
During the trials lock gates will be sealed with ash and padlocked to prevent them being used and water coming into the canal will also be controlled. The level in the canal will be monitored and BW staff will walk the pounds to identify areas of loss. 

Following the test a volume calculation will be made and a leakage rate determined. Because the stilling tests take place overnight there should be little inconvenience to boat users.

The locks involved in this test are Bath Top Lock (13) and Buckley's Lock (15) and Barratt's Lock (16) at Semington. They will be locked at 3.30pm on Wednesday 9 March 30 and re-opened at 8am on Thursday 10 March 2011.
