New Pond, Summer 07
Digging the hole |
|
A
boat has been described as "a hole in the water into which you pour
money." A pond might be thought of in a similar fashion – except that
it can't, in the end, sink. And, of course, the object is to pour in
water. |
It's a good idea
to find a contractor who's dug a pond before, who likes doing it, and
who knows local conditions. The shape you're after is often artistically
irregular to imitate a "natural" farm pond. |
Digging a pond is
similar to other earth-moving projects in that you can only guess what
you're going to encounter once you start scraping away the soil. |
Our contractor,
Kent, not only loves digging ponds, he lives a mile from here. He knows
only too well that we farm on top of a pile of big rocks. When he saw
the rocks that came out of the minor excavation for the barn, he expressed
concern there might not be enough dirt to complete the dam. In the
end there was enough but he wasn't far off. |
Of course, the contractor
is only in evidence at the beginning and end of the project. The real
artist is the equipment operator. Tom told me he has been operating
track hoes and the like for 28 years. It showed. He used the hoe to
pull the rocks, load them into a rubber-tired loader, and to rough-out
the hole. Then he used the blade to shape the bottom and to push the
spoils up the sides. |
Working his way
around the hole he built up the dam and shaped the inside topography.
Up and down, up and down. He could tip the ungainly machine over the
edge of the dam so gently you’d think it was level ground. Then he
shaped the top of the dam by driving around it with the blade angled
to push dirt to the outside. |
He stopped after
each sequence to check his elevations with a laser level. The hole
gradually got deeper, the dam higher, the substrate got finer, and
the shape more artful: consistent slope inside and out, rounded inside
corners, level and flat dam, smooth dirt surface. It was engrossing
to watch the fine and delicate touch he could command from the huge,
awkward machine. |
It is a beautiful
work of art! |
Lining the pond |
|
The pond liner followed. |
A single huge piece (15,000 square feet) of heavy duty (36 mil) reinforced polypropylene. It was unrolled and dragged into place by hand, with the help of a skid-steer, by a team of laborers. |
The movement was
accomplished inch-by-inch by shaking it like a rug to capture air under
it. The bottom of the hole was akin to Death Valley in the relentless
blazing sun and temperature near-100 degrees. |
The black plastic
quickly became too hot to handle with bare hands. |
And yet the sweating
workers deployed it in good humor. |
The edges wrap
over the sides of the excavation, are trimmed and tucked into a trench,
and buried in soil. |
And there, finally, was our new farm pond, ready for water. |
The very next day high winds threatened to billow the liner into Kansas so I hurriedly began filling it. |
Our pond holds about
425,000 gallons (1.3 acre-feet) of water and covers an area of about
a third of an acre. |
The primary purpose
is for irrigation water storage but there’s no rule against swimming! |
