Chatham was given the name East Hampton, which is said to have been selected by some of it's first settlers who had previously lived in Eastham, Mass. The first settlers were attracted there by the fine mill site, or water privilege, at the outlet of Lake Pocotopaug, where a forge had been erected in 1743. Lake Pocotopaug is about nine miles in circumference, averaging about ten feet in depth, has two charming islands, and is fed by springs entirely. Rain storms have very little effect in changing its depth. There is evidence that the land and its islands were favorite places of resort for the native Indians, probably of the Mattabessett tribe. It has always been a favorite resort for fishing, and summer vacations. There is a legend connected with the lake which passed from the aborigines to the white settlers hereabout, and handed down from generation to generation, to the effect that a beautiful Indian maiden sacrificed herself here by direction of the Great Spirit, on the promise to her that no persons should ever be drowned in its waters.
