At least you missed the two green bouys in the dark. Sunday lunchtime an EA launch went the wrong side of the bouys in broad daylight.
Instructions on the lock operating pedestal tell you to close the gates & empty the lock end of story
Not true for all rivers either though.
The best bet is to follow local instructions on individual locks. Locks requiring gates and sluices to be left in a specific way often have a list of instructions adjacent to follow.
Canal locks are an easier affair, leave the gates you exit from open with the sluices on the gates closed, unless of course there are instructions that say otherwise.
Mike, of all the discussion and banter on this thread I find this argument of yours the most compelling. Many canals rely on on surface water drainage and have no natural flow to keep water levels high, particularly in times of drought. Witness the Basingstoke Canal which is usually closed throughout the peak summer months because there is just not enough water in the upper levels to sustain repeated lock movements.I agree that for other rivers, with proper gates.
BUT on the general canal system with a preponderance of LTTTs Best Practice is to leave all gates closed.
My take on the reason is that on a river there is always an amount of flow, so a small amount of leakage through a top gate is of no consequence.
However, on a canal with little or no flow (as when there is no traffic), then a series of leaky top gates can waste a lot of water.

To some extent, the Thames is also vulnerable during a drought such as we experienced fairly recently when lockings were restricted. In such circumstances leaving all gates and sluices closed is nothing more than responsible behaviour.
Situation isn't helped when the EA's own instructions and literature are at odds with each other and unlikely to see any reprints of The Users Guide To The River Thames in the foreseeable future with cash so tight.
