And you think you had problems spelling your city! From childhood I've had fun just pronouncing the name of this lake. It's in Webster, Massachusetts, and some people cheat and call it Lake Webster, Lake Manchaugg, or locals often just call it The Lake.
The name, as many name places, came from an Indian language. It's said to mean
You fish on your side, I'll fish on my side, and nobody fishes in the middle.
