Millstone
River for smallmouth bass, northern pike
The Millstone River originates in
western Monmouth County, flows through a section of Middlesex County into
Mercer County and Princeton, and enters Carnegie Lake near the mid-point. The
water spilling over the lake’s dam and flowing north and east is the Millstone
River, although Stony Brook is a sizeable small river where it enters the
lake’s head. The Millstone begins and ends as a Piedmont Plain, mostly mud bottomed
river, but Stony Brook is the state’s southernmost predominantly freestone
stream. Three miles further south, the Shipietaukin Creek runs over gravelly
slates and broken rock for a mile or two of its longer length, yet most of
Stony Brook flows through the hilly region of Mercer, and the swift water
flowing over rocks at least used to hold excellent smallmouth bass populations.
Virtually none of these bass make
their way into Carnegie Lake (good for largemouths). But the Millstone has
smallmouths despite lack of many rocks and gravel. The bass both run upstream
from the Raritan River and make their way from Beden’s Brook—another Mercer
County freestone stream—which flows into the Millstone at Rocky Hill. From what I understand years after I posted this article, northern pike are no longer stocked by the state, but pickerel may seem more common than smallmouths, largemouths too, but one
spot in particular used to hold a number of smallmouths willing to hit on a given
afternoon.
This is the first time I’ve divulged
a very specific location in more than three years’ column writing. I hope I didn't burn anyone else’s favorite spot and don’t believe I did, since I passed over the Wilhousky Street Bridge every other day for almost six years. In all that time, I never saw anyone fishing the Weston Causeway Dam
race in clear view as I passed over. Since those years of working as a courier, the Weston Causeway Dam was removed.
My son, Matt, was seven when we
parked near the Manville bridge in Somerset County to fish the area of the dam.
That was August 2006, and for a couple of months Matt had been excited about
fishing this piece of the Millstone for muskies. I had read and discussed with
him a peculiar article I liked in The Fisherman
magazine which recommends this spot for just that species, and while it isn’t
impossible—muskies are stocked in the Delaware and Raritan Canal and find their
way into the Raritan River and then into the Millstone—northern pike are much
more likely caught, since thousands have been stocked in the Millstone by the
state over the years. Oddly though, I've heard of no one actually catching pike in the Millstone. By comparison, Passaic River pike thrive, but I don't know why a discrepancy has existed. I have heard of a pike caught in the Raritan River, obviously having washed down, and a pike caught in the canal, possibly because of a floodwater transfer from the Millstone. One other unlikely catch is walleye. The same article
featured a photograph of a walleye apparently caught in the Millstone at
Wilhousky. They’re not stocked in the canal or the river. They make their way
into the Raritan from the Delaware, by way of the canal. State Department of Environmental Protection Division of
Fish and Game personnel reportedly tallied electroshock recovery samples from
the Millstone last year, and these included one large walleye.
Of course, Matt and I caught no
muskies or walleyes. We caught no northern pike or largemouth bass either, but
I was pleasantly surprised to experience catching three smallmouth bass, which
slammed our small spinnerbaits as the blades pulsed through the fast water
below the dam. Two bass were very good size, weighing more than a pound-and-a-half. Obviously, a little fast water combined with rock-like concrete is a
smallmouth bass magnet. I suppose any walleye in the area would frequent the
fast water also. Walleye have been caught on occasion in the canal for
decades—always at any one of the nine locks in fast water. You may have to fish
all nine locks at least nine times each to hook a walleye, but these are the
places where they take residence. Smallmouths at Wilhousky are an
easier catch.
They won’t be for long, since the
Weston Causeway Dam is slated for removal soon, probably next summer. This is
why I can tell you about this spot in good conscience. It deserves some honor.
Dams are removed for good reason,
since rivers liberated improve ecologically and fisheries increase. Once the two
Millstone dams go, shad and herring may swim as far upstream as Carnegie Lake
dam. More smallmouth bass will rise from the Raritan too, since at present the
Weston Causeway Dam stops bass from swimming further, although some fishermen
surely release bass on the upstream side.
I guess an interesting project for
the Millstone would be the introduction of tons of rock and gravel on the
stream bed, but I’m only dreaming. Besides, it’s got current sluices, eddies,
and especially downed trees and brush making excellent pike, pickerel, and
largemouth habitat. It’s a river for kayakers and canoers, and will be safer
without temptation to go over a dam and get submerged in the circular current
below.
