Magic by the lake / Eager, Edward

On a vacation with their mother and stepfather, Jane, Mark, Katharine, and Martha find themselves overwhelmed with a lake full of magical adventures after Mark captures an ancient turtle that seems to have extraordinary powers.

When wishing for magic, it's hard not ot wish for too much. If Jane, Mark, Katharine, and Martha had stopped to think-oh, if they had only stopped to think! They would have ordered magic by the pound, or by the day, or even by the halves as they had in Half Magic. But no, they asked for magic by the lake-and now they have to deal with a whole lakeful of enchantment! Soon the children are awash in magic. They find themselves cavorting with mermaids, outwitting pirates, and with the help of a cranky old turtle granting a little magical help to the one person who needs it most.
