So we have this beautiful, mostly open meadow towards the eastern edge of our property which, judging by the number of stumps, used to be a mixed grove of conifers and oaks, all burned down by the big fire which swept through about 40 years ago.
Something about the meadow caught my attention. First, I noticed a few oaks at the edges of the meadow which were pretty mature, and probably started growing soon after the fire, but were dwarfish, standing only 4 or 5 feet high. Then I noticed a couple of large, bunchy cluster of willow like bushes in the middle of the meadow.
It became clear the aquifer came close to ground level in the meadow, which was drowning the dwarf oaks and the reason why the meadow stayed green pretty far into the summer.
Over the course of a few years, I dug some test holes and finally settled on the most likely spot and starting with a post hole digger, and then a shovel, dug a bowl shaped hole a few feet down. I didn’t hit water, but watched the hole off and on for another year, and observed the clay at the bottom of the hole stayed moist into summer.
The next step was to acquire a hand well auger and a couple sections of extension pipe. The auger is pretty much what it sounds like, you turn the handle and it acts like a big drill in the dirt and you pull out the dirt one auger load at a time.
I was able to get down another 5 or 6 feet, for a total combined depth of 8 or 9 feet and though the material pulled up by the auger was moist, still no water.
I waited for winter to observe the test hole and see what would happen when the water table raised from the rain and snow.
Bingo.
So I started digging out a pond. After digging up a couple dozen wheelbarrows of clay and dirt, it became clear that I would not in fact be digging out this pond.
The pond became part of a larger project which included first hiring a crew with a masticator to clear the old road leading to the meadow, and then arranging for an excavator to come out and properly dig the pond.
Nathan from MTC Construction showed up with the excavator, and after leading him to the meadow and discussing the project, he started in.
After a few hours, he’d scraped out the general bowl shape in the general diameter and then, still not hitting water, tenaciously kept digging down until… water!
By the end of the day, he’d pulled out an enormous amount of clay and dirt and it became clear that the project couldn’t move forward until we could get the bobcat with a large bucket out to work with the excavator to move and spread all the material.
Finally, the day came and the crew arrived and after several hours the job was complete!
The bowl of the pond is about 40 feet in diameter and slopes down 7 or 8 feet to the waterline which in the photo has risen close to about where the top of the aquifer is. The hole goes down another 5 or 6 below the waterline in more of a steep cylindrical fashion.
One of the faces of the bowl is very moist and has formed a seep field which is causing the pond level to rise very slowly.
The intention is to provide a year round source of water for the local wildlife.
Some of the material dug from the pond was moved over and spread in a level circle around a nearby large shade oak, and I’m hoping to build a nice little visitor’s cabin under its canopy.
This fall, I’ll be out with many many pounds of clover and wildflower seeds to plant on the berm surrounding the pond and the face of the interior bowl.
Next spring will be glorious and magnificent.
