Premise: Pleasant Lake is a 479 acre lake located in Rockingham County in central New Hampshire, United States, in the town of Deerfield. The eastern shore of the lake forms the boundary between Deerfield and the town of Northwood. Water from Pleasant Lake flows north to Northwood Lake, then west via the Little Suncook River to the Suncook River, a tributary of the Merrimack River.
Hypothesis: The eastern shore of Pleasant Lake, located in Rockingham County, divides two different towns one of which is the town of Deerfield
