Do herons land on water

Some will try, but they have limits as to what they can do. One species of night heron has been observed "diving into the water" off a dock, but it was too buoyant to fully submerge. It caught a fish and then had to fly up off the surface of the water. (They can't "float" like ducks and sit on the surface of the water, though their feathers will keep them from sinking.) Most of the birds just get their heads or usually just their beaks wet. The heron isn't actually classified as a diving bird (they're wading birds). But don't tell the night heron.
