Lower Saint Anthony Falls Lock & Dam is a lessor known structure
in the Twin Cities area. The structure itself is closed to the public,
so there is no observation deck, and even the entry road is posted.
The river makes a sweeping turn, so you cannot see the dam by looking up-
river. Hills on both sides of the river hide the structure. The best
view is from I-35W, but that is a very busy highway, and it is not possible
to stop to take a photograph.
Despite not being well known, the dam is still a fairly large structure.
It has a 24-foot head. While there is no hydro-power at this dam today,
we can expect to see it in the future.
The photo above is taken from the east side river flats. This area is
open to people who have business at the University of Minnesota Tandem
Accelerator Lab. This is the only legal spot I could find to take a
photo of the downstream side of the Lock & Dam.
The photo above is another view of the downstream side of the Lower Falls
structure. It was taken from the 10th Avenue Bridge. This photo is only
possible with the collapse of the I-35W bridge, which would normally
block the view of the lock & dam from the 10th Avenue Bridge. Note
the nice view of the Stone Arch Bridge and the 3rd Avenue Bridge in
the background. The lock and this section of the Mississippi River was
closed from August 1, 2007 to October 5, 2007 following the
I-35W bridge disaster.
The photo below is the upstream side of the dam from the west side of
the river. The entrance to the locks is in the center right side
of the photo, while the spillway is on the left side. This photo
is taken from the parking lot at the Mill Ruins Park. Notice the
green metal structure of the old I-35W bridge in the background
spaning from the edge of photo across to the trees on the right.
Another view from upstream of the dam structure. This photo was taken
from the Stone Arch Bridge. The photo below was taken from below
the dam from the parking lot at the Tandem Accelerator Lab. The downtown
skyline is visible in the background.
The photo above is the University of Minnesota steam plant. It is
used to heat most of the Minneapolis campus. While this structure
is built right on the river, it is not a hydro power plant. It was
hoped that this building would be removed when it became obsolete
in the 1980's. Instead, the University invested millions to rebuild
the plant. This rules out using much of the east bank of the river
for parkland. Fans of the rock bank Pink Floyd think of the album
Animals when they see this building. While it resembles the powerplant
on the cover of Animals, that power plant is the Battersea Power Station
on the River Thames.
The photo below shows a patch of empty land between the U of M Steam
Plant and the Lock & Dam spillway. This is the location of the
former Xcel Energy hydro power station. The power plant suffered
scour (being undercut by water) leading to the building collapsing.
It was removed in 1988 and the area filled in. There are proposals
for future use of this land. The most popular seems to be a whitewater
rapids park.
