It's not a big lake, but big enough, yes. It's not too far from WHA, but you need a car to get there. That or get prepared for a very~long walk.
The lake is a rather small-to-medium-sized lake, since we all know how big lakes can get. The outer rims are, of course, sand, but there is grass too, and trees. Plenty of them. Quite a nature place.
At one side of the lake there's a very tall, formidable water slide, and at the other side there are little boats that you can cycle/row/canoe/etc.
Fishing is not allowed in this lake as it can hurt people who swim in there. Besides, there aren't fish in the lake. At least I hope so.
Any roleplays that take place in the lake must be set at summertime. Any other time is unacceptable, as the lake is closed at any other season. Lake is open from dawn to sunset, though students are allowed to camp there, as long as they have at least one teacher with them.
