A raindrop falling in New London, N.H. flows west to the Connecticut River and down to Long Island Sound. If it fell a few miles east in Warner, it would flow east to the Merrimack River and down to the Gulf of Maine.
How do I know this? Because of a very cool visualization tool called River Runner Global put together by a guy named Sam Lerner. Well worth playing with!
This is a very cool visualization but it is incorrect. If a raindrop falls on my farm, it goes into the Oyster River not the Pawtuckaway. Sam Lerner is brilliant but he doesn’t understand the Great Bay Water system.
