The Delaware & Raritan, or D&R, Canal, is a basically 40-mile-long pond. The water flows very slowly from west to east; it is essentially still. Access points generally coincide with bridges or locks.

The map above shows a nice put-in in northern Piscataway. This spot has floating dock, and is convenient to Route 287. The river is tidal at this point, and the flow will depend on that, and the season. If you go upstream from here, you may quickly run out of water! I made it to Bound Brook one day, but only by hiking through the ankle-deep riffles, towing the boat behind me. ( Which is why you should always have a piece of rope with you. Ahem - line! )

Lake Carnegie is a reservoir that straddles the borders of the towns of Princeton, West Windsor, Plainsboro and South Brunswick in Mercer and Middlesex counties in central New Jersey. The lake was created by construction of a dam along the Millstone River, though the lower portion of the lake actually follows the valley of its largest tributary, the Stony Brook, while the Millstone River crossed under the D&R Canal to the south. The lake is about three miles long, but only about 800 feet wide.
