Finale is Dec 3rd @ Hoosier Theatre!!!

The Ohio River was once no more than large creek. Its natural depth varied from a mere 3 feet to 20 feet. In times of drought or deep freezes traversing would have been easy. So, stories have passed for decades about how people have waded or walked from the banks of one side to the other. Slaves have told stories about escaping capture by walking, wading or swimming across the Ohio to evade their captures.

Then the steamboats came ...

At their creation, steamboats were at the mercy of the Ohio's water levels. When challenge with low water levels or treacherous conditions, cargo and crew would simply disembark and start over down river. Their large hulls and heavy loads required deeper pools of water to navigate freely. So in 1910, Congress passed the Rivers and Harbors Act, authorizing the construction of 51 locks and dams along the Ohio River to increase the overall depth of the Ohio and improve commercial traffic. Switzerland County had one such lock designated as Lock No. 39.

Then the diesel engines came ...

As commercial traffic increased so did advancements in propulsion. The diesel engine enabled commercials boats to carry a lot more cargo. As cargo increased, the length of commercials ships began to increase, which posed a problem for current lock systems. They simply couldn't contain within the locks the capacity of the ships being created. Enter the Ohio River Navigation Modernization Program which replaced "outdated" wicket dams and locks. Goodbye Lock No. 39.

Markland Hydro Dam - Duke Energy Markland Hydro Dam - Duke Energy

The current iteration of the Markland Locks and Dam is a 1395 ft by 150 ft high stationary behemoth sitting at mile 531.5 of the Ohio River. It connects Gallatin County on the Kentucky side to Switzerland County on the Indiana side. Its primary purposes are to provide hydroelectric power, allow Ohio river traffic to pass and to allow vehicle traffic to travel from one state to the other.

Work began in 1956 by the Army Corps of Engineers. At its completion in 1967, it replaced 5 of the original wooden wicket dams that existed on the Ohio River.

The Markland Locks and Dam has provided power to thousands of homes through its hydroelectric generators. It was the first non-governmental hydro station on the Ohio River. With recent generator upgrades now complete, and at a cost of $152 million, it now can provide enough power to 52,000 homes.

From 1967 to 1978, the primary purpose of the Lock and Dam was to provide power and allow river traffic to pass. Since August of 1978 it has provided access for cars and trucks to travel from Switzerland County, Indiana to Gallatin County, Kentucky as well.

Here's where it becomes a gem for Switzerland County. The Markland Dam Park sits on the Indiana side of Markland Dam, just on the western edge. It was acquired by Switzerland County through a lease with the US Corp of Engineers in 1990. Through many volunteer hours, the land was developed provide shelter houses with picnic tables and grills, ample parking, full bathroom facilities, playgrounds, a basketball court and baseball diamonds. There are probably rules when it comes to camping and fire pits, but clearly over the years their have been a number of both of those seen over the years. Please contact the Parks and Recreation department to find out more.

At the Park

Along with all the built amenities at the Markland Dam Park, there are many other recreational activities available for you to enjoy.

  • bird watching
  • photography
  • videography
  • watch little league
  • picnics
  • barge watch
  • Near the water

    If you have the ability to walk down concrete steps without handrails, there are 2 accesses to the Ohio River. One is just south of the Markland Dam Park, the other can be accessed by entering Duke Energy by car and then walking down those designated steps. If the river isn't flooded, here's a list of wonderful activities closer to the water.

  • hike half-mile downriver
  • fish(with license)
  • look at some rocks
  • skip other rocks
  • search for washed up treasures
  • pick up trash
  • On the water

    If you have a boat and want to participate in some of the most interesting fishing, you might want to oar yourself close to the Dam. It has become quite the spot for Youtubers.

    One last item that needs to be shared. If you're ever in the area of the Markland Hydro Dam and hear in the far off distance a sound resembling that of a circus, get to the Kentucky side as quick as possible. Go to the observation deck of the Markland Dam. You'll get a close up look at the Belle of Louisville or Delta Queen. Well worth your time and there is no admission charge.

    So, we don't have the mountains of Colorado or beaches of Florida or California, but we have a remarkable few acres nestled along the Ohio River. Take a break, take it in, you won't be disappointed.


    Protected by a noble at zero and at forty-nine you see all. Look carefully at about forty, the key is very small.

    The Clue

    So "Duke" Energy became the "Noble" and at step 0, the dam is protecting you from the river. At step 49, you can see a great panorama of the Markland Hyrdro Dam and the Ohio Valley. I placed the key at about step 40. The background image was a screenshot of one of the scenes of "Fresh Horses" and would have helped you find Key #11.

    The Location

    The location of the key, was on the 40th step of the river access stairs, starting from the river. It was likely stepped over by anyone who was accessing the river.

    Nick Carfield shares his excitement for thinking he "solved" this clue. Amazingly, he did find a key, but not this one ... at least not right away. Nick stayed persistent and didn't let go of the "49". His eventual solve (at the end of the video) did land him Key #5.
