Washouts, Bottlenecks Slow Race Flow
MAP OF MIURACE: BEGINNING EO END
1. Beginning of outlet pipe under highway.
2. Culvert under Franklin Boulevard.
3. Railroad diversion dam.
4. Location of Physical Plant.
5. Site of Anchorage boathouse.
6. Break in Millrace wall.
7. Intake dam near Judkins Point.
5 — Next Fall: Canoes, Boathouse
ROOM FOR ABOUT 20 CANOES will be provided in this boat
house, which is planned for a site east of the physical plant.
Subject only to the approval of the budget board, it will be operat
ing with canoes by fail term. The Student Union wu< operate the
canoe rentals. This is just one facility of u larger project “The
Anchorage," which Is planned for the future. The larger unit
will include dining, dancing and other recreation fucilites.
1 - The Plug
THLS IS THE LOWER OUTLET of the Mlllrace, after the
stream has flowed past all the Mlllrace houses. From this point,
the water flows through a SO Inch pipe for about 2000 feet under
neath the highway, before finally emptying into the river again.
3 — The Outlet?

THIS DAM WHICH ALLOWS water to overflow the ’race Into
a channel which heads to the river, could be re-built, In order to
provide for a much greater flow out of the millrace. Since engi
neers do not consider the outlet pictured at the left to be adequate
If the flow would be greatly niereased, this site would probably
be used to get the water out of the millrace. Althiugh It would
not Increase the flow past the Millrace houses, It would never
theless provide a sanitary flow.
7-The Dam Ain't Long Enough
THIS VKItlAI. PHOTO shows clearly two of the problems fared
In restoration of the mlllmee. Arrow 7 points to the dam, show
ing how the river has waahed a round the north end. The city
attempted to stop this had flow hy dumping rock and gravel
from the north bank out to the dam. This did not stop the washing
out, however, and now the river has gouged a large hole out of
the north hank of the river, carrying away almost three acres
oi city owned land. In addition to washing out the north hank,
thi*. current is directed to the south bank, where it is under
mining the unprotected hank of the Miilrace. Arrow 6 points
to the break in the miilrace canal which occurred in the 1940's.
The canal was dammed up on both sides of the break, and a pipe
carries the water from one side to the other.
6 —The Bottleneck; Fore and Aft
Till" TWO PICTURES ABOVE are different shots of the same
site. The photo oil the left gives a view of the washout from
downstream; tin' right photo gives the upstream view. When the
wull was wushed out in the HMD's, tlit* 'Race was dammed up oil
both sides of the break, and uu underground pipe was installed to
carry water from one side of the break to the other. The (frill
lr the lox-'r left hand corner of the right picture shows where
the water enters the pipe. This pipe controls the flow of the
inillrace, since all millraee water must pass through it.
