There has been a bit of a mix up with the lake owner resulting in the access code already having been changed to next seasons code.
It could possibly be changed back again untill the 31st May but the advice is that if the existing code doesn't work then use the new one. Also try this on your way out in case the owner changes it during the day and its different to when you arrived (as happened this morning). Apologies for any confusion / inconvenience caused.
so we could have been locked in
What is new code please
