There was no dam 40. A Dam was planned between Markland and Louisville,
but
when Herbert Hoover, an engineer, and at the time, President, toured the river in October of 1929 to,
among other things, determine the need for an additional dam.
Water levels were high from rains, the market crashed 6 days later
starting the Great Depression,
and that was it for dam #40. |

At the left is an "out-of-the-water" view of one
of the early types of dams. Hydraulics opened and shut it
to control water height. |
Meldahl opened in 1962, and replaced dams #31 (Rome, Ohio, below
Vanceburg) and #32 (Portsmouth, Ohio). Meldahl lifts the river 30
feet; Markland lifts it 35. Markland opened in 1963. Both
Markland and Meldahl have two locks, one that's 110 x 600 feet, and one
that's 110 by 1200 feet. Markland is at the 531.5 mile marker from
Pittsburg; Meldahl at 436.2. |
