hi, i was at llanberis yesterday 16/7/09 hopeing to sail my new fishing boat . but there are signs all round saying dont enter the lake as it has blue-green algie and not to use any form of sailing ie. canoes, swiming, animals, and model boats i persume, i hope i am not speaking out of line but when all you chaps and ladies, comeing from any distance can any body clarify if it can still be used on the 15and 16 of august. in the toilets there are signs with 3 levels and red is showing as highly dangerous . may be by the time it could be clear.
