I live on a lake in the lovely Village of St. James. Never ever have I noticed an odor coming from the pond...lake...ocean.
.
However, there was a terrible odor coming from my neighbors who loved to smoke in their lanai. I no longer have to put up with that disgusting odor now that my lanai is enclosed.
No odor from the lake....beautiful views and free entertainment watching all the birds. Priceless!
