Not to mention the skeeters! You would have to have a special sealed viewing room to keep stuff from getting into the rest of the house. You would probably be better off with a porch or deck off of the house over the pond.
Note a local fancy hotel (Woodcliff) has an indoor/outdoor pool which at the interface has a plexiglass divider that is from the ceiling down to just below the water surface so the indoors can be conditioned while the outside is, well, the outside. No critters to worry about, and the outside of the pool is fenced to keep the casual human invader out.
