In this week's great flood, eerie reminders of Johnstown 1889.
Knocks on the doors in the middle of the night rousted some 2200
people from their homes in Montgomery County, just north of the
District of Columbia. A "mandatory evacuation," said the knockers.
"The dam is leaking."
The dam in this case is an earthen pile that forms a lake called
"Needwood," and if it gives way a lot more than 2200 people will
need wood with paddles and motors and in a hurry. The Needwood
threat is but one of the horror stories of the persistent storms
that dumped more than a foot of rain on the hapless Eastern states
in a couple of days. But there is a lesson in Needwood as well as a
strange mathematical coincidence.
Twenty-two hundred happens to be the number dead and missing in
what we call the Johnstown Flood of Pennsylvania in June 1889.
Then, the South Fork Dam on the Little Conemaugh River burst and
sent an estimated 20 million gallons of water pounding through the
town of 30,000 people. It was, and is, one of America's memorable
natural disasters.
But was it natural, really? The area around the dam was owned by
the elite members of the South Fork Fishing and Hunting Club whose
rolls included some of the titans of early American industry. It
was suggested later that the dam had not been maintained, but
nothing came of these claims. The salient fact was and is that
people chose to live in what could become and did become a
sluiceway authored by a dam.
It has been part of the American heritage to build dams, to
wrestle nature to its knees, to conquer the natural bent of flowing
water. Recently there have been regrets. Notably some dams deemed
useless on waterways in the northeast have been taken down, it
having been discovered that species of salmon and anadromous fish
were disappearing, unable to reach their reproducing grounds. More
so-called "fish ladders" are being installed to avert similar
situations around dams of the great western rivers.
Nobody, not the most imbued environmentalist, expects to take
down some structures. Hoover Dam and its Lake Mead are there to
stay. (Remember the attempt to call it "Boulder Dam" when a
succession of FDR Democrats came to power during its construction?
Probably not.) Grand Coulee isn't coming down soon, either.
There is another place with a name more evocative than Needwood.
It is Great Falls, the city on the Missouri in Montana. Great Falls
is at the head of five "former waterfalls," the first of which was
first seen by Meriwether Lewis on June 13, 1805. The Indians knew
of the falls, told Lewis and Clark of their approximate
whereabouts. But it was Lewis who, forging ahead, at first heard
and then saw "the grandest sight ever beheld." Three hundred yards
of river falling over a precipice of 80 or 90 feet. Lewis regretted
his limits of description, "that I might be enabled to give to the
enlightened world some just idea of this truly magnificent and
sublimely grand object." Tough, enlightened world, a dam now sits
astride this first falls, and four more concrete creations bestride
the four that lie up stream. One falls, named for Colter, explorer
of Yellowstone Park, now lies submerged in the bay formed by
another of the dams, which corral the water and send it shunting
through generators at the sides and base of the dams.
A chronicler of the expedition, the late Stephen Ambrose, urged
in speeches late in life that Great Falls give thought to
reclaiming this lost beauty, asserting that the dams obscure one of
the wonders of the western world. At the least, Great Falls might
consider a more descriptive name -- Great Dams ?
But back to Needwood. It wasn't until late Thursday night that
officials told the 2200 evacuees that they might safely return to
their abandoned homes -- this time.
