Amwell Lake Wildlife Management Area
East Amwell Township, Hunterdon County, NJ


Located off Route 31 east of Linvale (southeast of Ringoes).

It can be reached from Trenton or Pennington by driving north on Route 31 to the Harbourton turn-off; then proceed about a quarter of a mile to access road on right.

Approaching from the north on Route 31, the access road is on the left about one quarter of a mile before the Harbourton turn-off.

(For maps see:

The picturesque lake is surrounded by rolling farmland at the foot of the Sourland Mountains in southern Hunterdon County.

Parking for about 50 cars. Access to portions of the shoreline is difficult because of marshy conditions. The lake is at the headwaters of the Stony Brook-Millstone river system

Karl Anderson reported that this is not much of a place for botanists. He said to take it off my list.  But I took a look anyway and it is not so bad. I was able, with some difficulty to walk around the lake. There is a good cattail and other type marsh here.

Counted 109 Canada geese on the lake.
