FERNBANK DAM
Before dams were built on the Ohio you could walk across the entire width of the river in periods of dry weather, obviously traffic by boat would be impossible. Congress authorized the canalization of the Ohio in 1878. There were a total of 49 of these dams and they raised the level of the river to 9'. Fern Bank was dam #37 and dam #36 was constructed in the Coney Island area. Its strange but I have never seen a postcard of the Coney Island Dam. Has anybody else? Fern Bank was constructed in 1911 and lasted until 1963 when a new group of 19 new dams were built which raised the level to 25' which allowed the passage of the bigger tows that were beginning to be used. The non-postcard image below demonstrates the plight of the Ohio river boat in times of very low river depths before the construction of the dams. This photo was taken in the 1880's with the L & N bridge in the distance.
These dams were called "wicket" dams. The dam itself was 900' long consisting of 225 wickets each one 16'11" in length, 3'9" wide, and 12" thick at the lower end and 8" thick at the top. There was a 3" gap between them. They were oak and steel barriers that could be raised or lowered depending on the height of the river. When lowered they would lie flat on the river bed. The lock was on the Ohio side and was only used when the wickets were up in low water conditions. The locks were only used about 5 months each year. It took about 10 minutes to lock a boat thru the dam. On the Kentucky side were 3 discharge gates that were called bear traps. The bear trap dams were formed by four concrete piers 80' apart. Compressed air from the power house was used to raise the leaves of the dams. The name comes from the appearance of the trap when it is up. It forms an A - like structure which was supposed to look like the deadfall used in trapping bears. These gates would allow excess water to pass without lowering the wickets. It also allowed the passage of drift wood and ice buildup in winter. The wickets were raised and lowered by a man using an iron hook riding in a maneuver boat you will see in many of these cards. The force of the water was used to help raise the wickets. Below is a wicket on land in an open position. The 2nd image is a model of the next dam downriver from Fernbank, dam 38, at Maxville, Indiana. It was built by the lockmaster there.
On the Ohio side at the highest known flood stage were built in a row, the office building, the power house, a warehouse and four lock tender's homes. At the start of WWII fences were put up around all the dams to help prevent sabotage. After the war locks 36 and 38 fences were removed but Fernbank's were retained. Apparently the Lock Master (James Stutzman) considered the grounds to be his personal domain, and would prevent people from entering for reasons known only to him. The area is now a park.

A note of interest: any boat that is an official carrier of the mail gets priority preference over any other boat waiting to lock thru.

The First Day Cover above was issued for the Ohio River Canalization issue on October 19, 1929. This cover has a cachet of the Emsworth Dam, not Fernbank. Emsworth is in the Pittsburgh area.
Anderson Ferry is the only ferry in the Cincinnati area still in existence (it's not too far away from Fern Bank). Records show that there has been a ferry at this location since 1817. Confederate General Morgan first crossed the Ohio here in 1863. The Kottmyer family has been operating this ferry since before the Civil War. Back then it was called a "Horse operated" treadmill ferry boat. Both of the cards below show the Boone #5 ferry. That means this ferry is the 5th one operated by the Kottmyer family. For reference in 1949 the ferry was called Boone #7.

The next section show the Marine Dry Docks which were located across the river from Dayton KY. in Fulton Ohio at the bend in the river. Cincinnati first started to build steamboats in 1816. By 1826 57 had been completed. From the late 30's the boat yards launched 30 steamboats a year over a 20 year period. By the 1880's nearly 1000 boats were built here.
The images below are not postcards.

The Marine Railway Company was not only the largest but it was also the longest lasting boatyard in the Cincinnati area starting in 1847 and lasting until November of 1919. The five images above give you a pretty good view of how the boats were raised and lowered. Heavy timbers laid out in pairs, and securely anchored in position, extended from the top of the river bank down to below water level, these were called ways. There were eight pairs of ways in each group. On each pair of ways was a sliding cradle that were connected to heavy chains that ran up the hill to large winding drums. These drums were connected by a long shaft that was driven by a powerful steam engine, with clutches operating through nine sets of gearing. These clutches allowed any or all the cradles to be raised or lowered simultaneously on the ways. The bottom of the cradles rested on the ways while the top part was horizontal to hold the boat level. To raise a boat for repairs the cradles would be lowered into the river, the boat would be floated onto the cradles and would then be lifted up the riverbank to the desired position. The boat would then be supported by a system of blocking. The cradles could then be lowered to raise another boat.
