Something for the lake

We had a day off today and went to a large market being held in a town about 40 minutes away. Apart from the food and wine it mostly sold crap stuff that you would not want to buy! However we did come away with a coupe of things for the chateau lake - no idea how we are going to get on with them but have been googling like crazy to find out what we should do to introduce them to their new lake home!!
