In Texas we call them ponds.
People love ponds. One of the most frequently asked questions I get on land/farm and
ranch listings is "Does it have a pond?"
I have been told that they are called different things in other parts of the country.
When conducting my MLS searches for properties with ponds I have noticed that in the
comment sections some of my fellow realtors will state things like, "Good place for a pond"
etc. It makes in come up in our searches if a keyword search has pond in them. HMMMMM.
Food for thought.
