On the cold and cloudy day of December 11, 2010, we went to Millstone Aqueduct in Princeton/Plainsboro,
New Jersey, USA of the Delaware & Raritan (D&R) Canal State Park for bird watching. The D&R Canal is in
parallel with the large body of water of Lake Carnegie  in Princeton. We saw this great blue heron and mallard
on the icy cold water.
Three of many colorful mallards in the park.
Another great blue heron in flight over the icy surface.
That great blue heron was flying toward the tree.
The towpath along the D&R Canal provides very nice hiking trail for bird watching and hiking. In warmer
seasons, this hiking trail is very beautiful as shown near the end of my web page at:


The "D&R" Canal State Park is a continuous 35-mile greenway that extends from Trenton to New Brunswick in
New Jersey. Bicyclists and pedestrians can travel from Port Mercer to New Brunswick along the canal
towpath, and canoes can navigate the entire length of the park with a minimum of portages. The Princeton
segment is about 6 miles long.

Carnegie Lake is a prominent and attractive feature of this Princeton segment of the D & R Canal State Park.
Owned by Princeton University, Carnegie Lake was built in 1906 with funds donated by steel industrialist and
philanthropist Andrew Carnegie to provide a rowing course for Princeton University rowing and water sport
teams. It was created by the construction of a 650-feet long dam at Kingston that impounded the confluence of
Stony Brook and the Millstone River. The lake is three and half mile long between Princeton and Kingston and
from 500 to 1,000 feet wide. Princeton University allows public access of Lake Carnegie for fishing, ice skating,
and lakeside enjoyment from the D&R Canal towpath. The towpath, which includes the Millstone Aqueduct and
Footbridge, runs along eastern shore of Carnegie Lake, and visitors can walk, run, or bike the length of it.
Three more views of the adult great blue heron with long shaggy feather on the neck.
Many more mallards standing at the edge of the ice sheet on the lake, one is in the water on the left side.
That great blue heron was landing on a tree branch.
Many red berries along the D&R Canal and along the lake shore of Lake Carnegie .  
Shortly after turning right from U.S. Route 1 (Southbound) into Mapleton Road in Princeton/Plainsboro, one
sees this sign of road junction. Continue on Mapleton Road for about 0.3 miles to reach the sign, the parking lot
and the Trail Head of Millstone Aqueduct - D&R Canal State Park.

This is where the Millstone River meets Carnegie Lake and D&R Canal. It is called Millstone Aqueduct after the
aqueduct that allowed the Millstone River to flow under the D&R Canal. The D&R Canal and Millstone River are
flowing at 90 degree crossing eacher, but at different heights. There are three footbridges here for visitors to
cross over the canal and over the Millstone River.

Zoom in for a closer view of the head of one of several great blue herons that we saw in this park. I was using
my new compact super-zoom camera, Canon PowerShot SX30 IS, with 35X optical zoom.
The colorful male mallard was walking on the ice. It had been quite cold in last few days such that most of the
water surfaces in this park were frozen. But there were still some open water surfaces.
Many Canada geese, some were in the water while others were standing on the ice.
More Canada geese standing on the ice. Behind the tree line at the far end of the Millstone River/Lake is the
Lower Harrison Street intersecting U.S. Route 1 in Princeton/Plainsboro.
Front view of the great blue heron standing on the ice.

I visited this location again in the summer season on July 17, 2011 to take pictures of the River-Over-River in
Princeton. This picture shows the D&R canal in an aqueduct which is above the Millstone River which is flowing
under this aqueduct and into the Lake Carnegie on the far side of this picture.
This picture shows some people in a canoe in D&R Canal and the footbridge across the D&R Canal. On the
right edge of this picture is another footbridge in parallel with D&R Canal across the Millstone River.
This picture shows the two footbridges on both sides of the aqueduct/canal. The Millstone River flows
underneath this aqueduct and the two footbridge into the Lake Carnegie which is on the left side of this picture.
