This source specifies 154' (47m) as the height of the dam.
This was the first concrete dam that was taller than 95' (29m). The construction of this dam included the invention of steam-powered machines to mix the concrete.

asce
As with most dams in California, this one was built to provide a water supply. In this case, for San Francisco. Chief Engineer Hermann Schussler advised the board of the Spring Valley Water Co. to buy the land of the 23,000-acre San Andreas Valley watershed, which they did.

asce
Hermann was aware that concrete shrank and became hot as it cured, so he built the dam as a series of interlocking blocks. The first set of blocks in a layer would be built like a checkerboard. Then the empty spaces would be filled in. The center of a block of the next layer would be built over the intersection of four blocks in the previous layer. And this photo shows that the blocks where keyed into the adjacent blocks. This created a dam that was strong enough to survive the 1906 and 1989 earthquakes without any significant damage even though it is only 1,100' (335m) east of to the San Andreas Fault.

asce
The dam is 600' (183m) long and contains 157,000 cu. yd. of concrete. It has a total capacity of 19 billion gallons. A 44" (1.1m) wrought iron pipeline that is 89,500' (27.3km, 17miles) long delivered the water via gravity to a terminal reservoir in San Francisco. "The pipeline performed well for many years before being replaced."

In 1985, Captain Ed Barnaby had nine tugboats in his yard. Business was already half of what it was two years earlier when they moved 4,000 barges on the lake. In 1985, only one of his tugs was working. [ChicagoTribune]

They have a crawler crane and a floating drydock.

Another view of the crane and of part of the drydock. The towboat is Tanner. There is also an interesting trailer to the right of the crane.

Obviously, this photo was taken from a semi-truck on the Skyway Bridge.

I wonder why they rented a mobile crane since they own a crawler crane. Or did they get rid of that crane?

Oakton Avenue: (no Archived Bridge Hunter; Satellite)

Building bridges across the channel had to be a significant fraction of the cost of digging the North Shore Channel.

Victor StLawrence What is the average depth of the channel?
The North Shore Channel is generally between 5 - 7 feet deep when the Chicago Area Waterway System (CAWS) is at it’s typical operating height. At some points, it can go as deep as 10 feet and as shallow as 3 feet. You may learn more about the CAWS here: https://mwrd.org/chicago-area-waterway-system

Dennis DeBruler commented on Hilary's comment
As MWRD mentioned, Northeast. The railroad tracks in the right background were C&NW, and the water towers in the left background were in Weber Yard. 1953/55 Evanston Quad @ 24,000

When I looked at a satellite image, I noticed that the bridge is significantly wider than the street. I presume that is to have more lanes of traffic crossing McCormick Blvd. during a green light. If I ever get up that way again, I need to use the rowing dock to get a photo of the underside of the bridge. I'm currently guessing that I should use the label "bridgeGirderConcrete" instead of "bridgeGirderSteel".

Historic Chicago River Mouth and Harbor

(Satellite)

These notes cover the time period when sails and steam powered the ships and tugs. For later views of the Chicago River mouth, see S-curve and Chicago River Controlling Works.
The Illinois Central Grain Elevator notes also have some images of old ships.

Some sources consider the entire river to be a harbor.

Between 1816 and 1834 the sandbar at the mouth was channelized.

This amazing vintage gatefold woodcut engraving arrived this week.  It is an original two page fold-out illustration from Harper's Weekly dated June 1884 and is nearly 140 years old.
It shows a birds-eye view of an extremely busy Chicago harbor mouth and is lavishly detailed.  It gives an excellent feel for the hustle and bustle of a large early Great Lakes port, capturing the smoke, soot and general congestion of the river mouth.
There is a lot to unpack in this image, with many interesting vessels, including the sidewheeler Chicago, a fully rigged barkentine and several other interesting vessels.  The Life Saving Station is visible at the pierhead and a great deal of Chicago's early waterfront is rendered with excellent detail.
This image was too big to scan so I photographed the page, which reduced the resolution and introduced some coloration.  It was made from the top of the lighthouse at the harbor entrance and was likely adapted from an original photograph, which no longer exits.

Chicago River Mouth in June 1884

When I glanced at this image, I knew it was old because:
  • black smoke was still condered a sign of prosperity
  • the Illinois Central still had both of its grain elevators
  • the Interstate Exposition Building (the one with three domes) is still standing
  • some of the ships have sails
  • the lumber trade is at the mouth rather than down by Lumber Street on the South Branch
  • there is no fill east of the IC trestle along the lakefront
  • there is a railroad bridge connecting IC and C&NW's Navy Pier line

This excellent early Chicago stereoview arrived today.  It shows a scene on the Chicago River looking east out the harbor mouth at Lake Michigan.
The card was made about 1882 and is a republication made by the Chicago stereoview publisher George F. Gates.  The original image is a bit earlier, dating from about 1880.

This imperial size stereoview card of Chicago Harbor arrived today. It was published in 1885 by Woodward Stereoscopic Company of Rochester, New York as part of their Chicago, Ill and Vicinity series.
It is titled Chicago Harbor from Lake Street Bridge and shows a harbor tug working on a large schooner with a grain elevator in the background. When I bought the view, I was pretty sure I saw a nameboard on the schooner, but unfortunately, it was just one of the scuppers. Additionally, much of the view is obscured by the tug's steam, and the exposure is also somewhat uneven.
The tug is a bit more interesting. She bears an ornate V.O.T.C on her bow, signifying the Vessel Owners Towing Company of Chicago. They owned about a dozen tugs, but only a few at Chicago during this period. Based on the date of the view, which is known with some accuracy, she might be the tug Thomas Hood, but I'd welcome other opinions.

It's been a good week for new acquisitions.  This stereoview of the Chicago River arrived today.  I believe it shows the Clark Street Bridge in the distance as a tug brings a three-masted schooner up the river on the right and a large passenger steamer approaches on the left.
The card was extremely dirty when I received it with the vessels being mostly obscured.  I cleaned it gently with a damp cloth and distilled water, which removed a surprising amount of dirt and grime.  The cloth was black when I was done.
This is a view I've never seen before and appears to be a 1880s or 1890s reproduction of an earlier original as evidenced by the single panel that comprises both the left and right images.  The actual image looks to be from the 1870s.  No names are visible on the vessels but the flag on the stern of the steamer is nearly legible.

Terry Gregory: Very interesting. My GGGF was a well known Chicago Shipbuilder from 1855-1884. I’ve been researching his boats for 20 years. Here is my research (also a Chicago Historian).

Brendon Baillod: Terry Gregory That's an excellent piece of research! Thanks for sharing. I come across John Gregory regularly in my research and have researched or own images of many of the vessels he owned. I see them regularly in vessel enrollments, news micros, USLSS Annual Reports, MVUS registers and Inland Lloyds/BLU registers.

In the background on the right is the steamer Iowa. On the left side of the image is the schooner W. O. Goodman of Chicago. The freighter Syracuse of the “New York Central & Hudson River R.R. Line” is in the background on the left side of the river. 
In the foreground on the left is the tug Harry C. Lydon towing a barge. The wording “Chicago & Great Lakes D.&D. Co.” appears on the vessel’s bow. In the background on the right is the tug A.B. Ward which appears to have towed a barge of coal to alongside the Virginia for fueling.

Here's a rare, early Great Lakes nautical woodcut I picked up last week.  This view of Chicago harbor dates from 1885 and was published in Frank Leslie's Illustrated Newspaper of January 16, 1886.
It shows an extremely busy Chicago harbor with a great deal of intermodal transportation.  The railyards near the waterfront were immense even in 1886, while the harbor traffic includes schooners, tugs, a sidewheel steamer (probably the Sheboygan or Muskegon) and a large number of steam dredges actively engaged in deepening the basin south of the harbor pier.
This woodcut is relatively uncommon and this is the first time I've seen it on the market.  This is a photographic view as it was too large for my scanner bed.  Thus, the uneven lighting.

North Damen Avenue over North Branch Chicago River

Source from Library of Congress North Damen Avenue Bascule Bridge was replaced crossing the North Branch Chicago River in Chicago, IL is identical to the 18th Street Bridge crossing the South Branch Chicago River.

It is rare for Chicago to use a single-leaf trunnion bridge.

Since the Grebe Shipyard closed, many of the bridges on the North Branch no longer need to be movable.
