There are about a thousand lakes in New Hampshire, and about 100-thousand registered boats.
Throw in another 30-thousand that don't have to be registered here, some sunny summer weather, and it adds up to a lot of people on the water.
Some say, too many people, and it's cause for concern.
The New Hampshire Lakes Association is holding a conference over the weekend to talk about how much use the lakes can take before they start to show signs of stress.
It's part of an effort to bring people together and make plans for lake protection, before the state has to make laws.
