The Aqueduct, Part 4: Fine Tuning

July 22nd, 2013 | 2 Comments »

Plugging The Leak is not really fine tuning, but before we can fine tune — or indeed, before we can do anything more on The Aqueduct — we have to do it.

We thought the problem was the drain that enters the small holding pond below the driveway. We dug up a section along the edge of the drive, removed some perforated plastic drain pipe and backfilled with heavy clay soil. It wasn’t a big job and it took only a few hours. But it didn’t work.

We thought again. Could the cascade pond be leaking? (The cascade pond is the one surrounded by spirea. I showed a photo of it in The Aqueduct, Part 2: Building It )  We built the pond almost 15 years ago and it has worked perfectly ever since. Still, we could see that water was pooling on the driveway near the pond so we decided to investigate.

We drained the pond and dug out the big clump of iris pseudocarpus growing on the edge. Removing them was easy: the roots were so tangled that the plants came out in a single scoop.
These yellow flag iris came out in a single clump. We’ll replant some here by the cascade,
and put others in wet areas near the Skating Pond in the upper field.
That is, if we can pry the clump into smaller pieces!
When we built the cascade pond, we put an enormous rock on one side, as a sort of viewing platform. Removing that big rock wasn’t easy but once some of the smaller rocks were out of the way, it didn’t take too long. And it is one BIG rock. Ken, standing next to it, is over 6 ft tall. That means the rock is about four feet tall. And heavy.
Moving the rock away from the pond was hard.
Putting it back in place will be harder still.
With the rock out of the way, we could dig down, remove all the rough rocks under the drive, until we came to clay. We dumped in a lot more clay to make sure water couldn’t seep out of the pond and into the drains under the driveway.
We repacked the edge of the pond with clay to prevent water backing up
into the drain under the driveway.

Unfortunately, this didn’t correct the problem either.

Resolving it is absolutely necessary. If we don’t, water will continue to run down the steps that lead to the front door. Not a good idea in summer, and potentially fatal in winter when frozen water would transform the steps into a ski slope.

Plus the excess water is killing my special plant, Jeffersonia diphylla. Losing this plant would create a gap in my heart that would be very hard to fill.

My one Jeffersonia diphylla is not looking happy.
So neither am I.

I’m not sure what we’ll do next. This is discouraging because instead of enjoying The Aqueduct all summer, it is becoming a headache.

I won’t write about The Aqueduct again until we have solved the problem. I hope you will join me next week when I’ll write about England and some of the magnificent gardens we visited there.

Spring in Quebec comes late. It was mid-May before the ground was dry enough for trucks to cross the lawn. And we needed trucks to complete The Aqueduct. The Aqueduct on April 6. Snow still lingers in shady areas and everything is a mess. The reflecting pool went in -- first concrete blocks, then steel plates to cover them. Inside the pool we added a square box with a perforated bottom. Water would drop into the box and seep out into the pool itself, eliminating splashing and keeping the water in

In my last blog post, I wrote about why we decided to build The Aqueduct (The Aqueduct, Part I: Why We Built It). I explained that we wanted to see and hear the stream that ran down the hill near the house, to replace some dangerous steps, and to create a water feature that harmoniously linked disparate elements in the house and landscape around it. I started planning this project in April 2011, but for various reasons the shovel didn't go into the ground until September 2012, almost a year

When my husband and I bought Glen Villa in 1996, we moved from a little lakefront cottage into the house next door. We acquired a property that had been loved and looked after beautifully. We counted ourselves lucky indeed. We often sat on the deck looking out towards the magnificent linden tree at the end of the big lawn. We ate breakfast and lunch there, entertained friends, enjoyed the view. Sometimes, in the background, we could hear water trickling over rocks, but we couldn't see the water. And most of
