Bren said >please tell me from where one obtains a permit for QMR? <

I get mine from :-
Senior Warden, Thames Water, Farmoor Reservoir, Farmoor, Oxon, OX2 9NS. I
believe they still cost £8 and you will need a small passport photo to go in
it, Bren.

But please only show it to Thames water staff. If you ever show it to the
birds, we will never see any at QMR again!!

Best Regards
Brian Clews

 

It was pointed out later in this exchange that this permit did not give permission to walk around the basin and only allowed access to the car park area!

It was also pointed out that " ...but TW reservoir manager at Staines does
not agree there is any access being extended to the site ..."

So, who knows?
