HOW SHALLOW WAS THE OHIO RIVER BACK IN 1905

July 7, 2026

Back in 1905 the Ohio River was not a single “shallow” or “deep” number—its depth varied wildly by season, place, and by whether you were looking at floods or droughts. But in the normal, non-flood season it was often only a few feet deep in many stretches, with some sections down to just 1–3 feet.

What the 1905 numbers actually say

The National Weather Service’s Ohio River history table for Cincinnati shows:

Low in 1905: 6.5 feet (recorded in October)
High in 1905: 48.3 feet (recorded in March)

Those are river levels relative to a reference, not direct depth in feet of water, but they tell us:

In the fall of 1905 the river was at a very low stage , close to what would historically be considered a “shallow” condition.
In the spring of 1905 it was at a high stage , close to flood territory.

In other parts of the river, especially upstream near Pittsburgh and in some bends and sandbars, depths at low water could be much less than 6 feet , sometimes just 1–3 feet in places.

How shallow did it get in bad years?

Even though 1905 was not the absolute worst drought year, historical descriptions of the Ohio help set expectations:

During severe droughts, the Ohio has been reported as “only one to two feet deep” in some stretches, enough to wade across.

In the early 1800s, the Ohio at Cincinnati was recorded at 11 inches (less than 1 foot) in very low conditions.

So while 1905 did not hit that extreme, it was still a river that could be very shallow in places during low-water periods.

Why the Ohio feels “shallow”

Several factors make the Ohio’s shallow reaches notable:

Natural variability: The river’s natural depth varies from about 3 feet to 40 feet in different sections, depending on season and location.

Dams and locks: Modern navigation relies on a series of dams that raise water levels in shallow stretches; without them, many parts would be too shallow for commercial boats, especially in late summer and fall.

Sandbars and bends: The river has many shallow sandbars and twisted bends where local depth can be just a foot or two, even when the overall “average” is deeper.

So, how shallow was it in 1905?

Putting it together:

In normal low-water conditions in 1905, many sections of the Ohio were likely 1–4 feet deep , with occasional places even shallower.
The October 1905 low at Cincinnati corresponds to a very low stage (6.5 feet on the gauge), which historically would mean noticeably shallow navigation and exposed sandbars in many stretches.

It was not uniformly across-the-board “barely a stream,” but it was definitely a river that could and did become quite shallow in places, especially in late summer and fall.

In short: in 1905 the Ohio River was often only a few feet deep at low water, and in some spots as shallow as 1–3 feet, making it a genuinely shallow river in many places during dry seasons.
