Pond v. Lake

One of the most common questions to the DEP or IFW biologist is what makes a Pond or Lake. Here are some comments from ME DEP/IFW - sunlight goes to the bottom of ponds; its the area or size; is it a kettle pond; truly some ponds are lakes and in Maine there is no Technical difference between the two. In fact some have the word lake before the name and some after.

In England they are called Lochs; out west everything is a lake, but in New England there is no standard.

Some thoughts across the country to decide - oh by the way no one I can find has a definition. Pond man or beaver made; lake made by creator; pond is filled by rain or stream - lake has stream and springs; its size; its depth; is the current in the body of water; its how clear it is; there is no standard; inlet v outlet; water temp on surface is difference than bottom; desolved oxygen at bottom; ph level; plants in the middle or a lot of alage; waves more than 12 inches; made by a glacier. These are just a few offered by biologists around the country. I say it should be depth, over 20 feet and greater than 10 acres is a lake. What do you think.
