Caland Ore Co., Steep Rock Lake, Ontario, 1954-56
Dan Moziar says: " I worked two summers (1955 & 1956) for the dredging firm
Construction Aggregates Corp. (CAC) of Chicago. There were two suction dredges in operation -- The Joseph L. Block and
the Clarence B. Randall, both (named after) senior executives with Inland Steel and Caland Ore. The dredges were
powered by 10,000 H.P. electric motors and each pump line had two more 10,000 H.P. motors on shore to help push the
dredged overburden over the land divide.
" I worked in the engineering office of CAC and the operation was headed up by
"Boots" Davis and Norman Proehl, two American engineers . . . .
Both of these men were football players and I believe that Boots Davis had been an All-American. Recently there was a
player with the name of Proehl playing for a ranked team (Notre Dame?) and I suspect that he was the grandson of
" I worked for an American civil engineer named Auggie Stoeffler from New Jersey, and I
believe his family owned a firm call the Stoeffler Knitting Mills. He was a great man to work for and I learned a lot
about engineering from him.
" I was an engineering assistant and dredge statistician, and we kept track of how much
overburden the dredges removed each month as CAC was compensated by progress payments. It was an interesting job for
an undergraduate engineering student. "
May 15, 1954: Taken from the Office looking south towards the work area
-- electric, mechanical and welding shops. Water elevation 1130.9.
June 26, 1954: 42 inch pipeline to discharge in Marmion Lake.
Undated photo of the tug Manistique. Probably taken in June 1954.
Aug. 7, 1954: One of the 10,000 HP electric motors probably for the dredge Joseph L. Block.
Dec. 4, 1954: Last dredge spud arrives by Kenilworth truck. I do not recall the name of the truck
driver, but he was a great driver. I believe he was entered in the Canadian Truck Drivers Rodeo event in 1954 or 1955
and I think he was in the top three in Canada. This spud was probably for the dredge Joseph L. Block.
Another picture of the spud being delivered in Dec. 1954. Not much snow!
Mar. 15, 1955: Earlier picture of Dredge Randall port quarter. Note the port stud is down and the
starboard spud is up, which is how the dredge "walked" into the cut.
Mar. 15, 1955: Pipeline discharge into Marmion Lake. Note the water is clear which probably means
a startup after a shutdown of the dredge and/or the pipeline for maintenance.
April 10, 1955: Derrick barge #1 used to service the dredges and monitors.
July 3, 1955: Picture of monitor barge Indiana Harbor after a landslide. Note the watergun on
deck. The monitor was used to undercut any large cliff banks to create small landslides and not put the
dredges in jeopardy. Obviously not successfull for the monitor this time.
July 1955: Engineering assistant and dredge statistician Dan Moziar checking the rate of flow at
the discharge end into Marmion Lake. Several times a day Dan had to drive to the discharge end of the pipeline and
measure the rate of flow (CFS) and also take a silt sample to calculate the average daily removal of the overburden.
The results of the several daily readings were then averaged and a production volume was calculated.
This volume was then averaged with two other calculations to produce a daily production figure. The dredging company
CAC of Chicago received progress payments based on the daily production calculations.
July 1955: Dan Moziar taking a silt sample for calculating daily dredge production.
Jan. 21, 1956: View of the dredge Clarence B. Randall pumping silt from Falls Bay.
