David examined the surrounding ground.
The covering appeared to rest above a small old access chamber, possibly connected to a buried collection system.
The structure had deteriorated over decades.
Its condition was unknown.
Nobody should stand on it or attempt to enter it.
Sarah looked toward Eli.
For a moment, her expression showed relief that he'd waited.
Nora smiled at him.
“You made the right call.”
Eli nodded.
But his eyes remained fixed on the ring.
“What is it?”
David studied the old map.
“Possibly access to a drainage collection chamber.”
Eli frowned.
“Like a well?”
“Not exactly.”
David pointed toward the drawing.
“Your grandfather appears to have used shallow collection lines to intercept a small amount of water moving through this soil layer.”
Eli leaned closer.
Nora continued.
“A seep can occur where water traveling through more permeable material meets a layer that slows its movement. Sometimes that water reaches the surface. Sometimes it remains just below it.”
Eli looked toward the damp soil.
“That's why the bed stays moist?”
“It may be part of the reason.”
He nodded.
David added, “But we need to inspect the system safely before making assumptions.”
They arranged a cautious assessment using appropriate equipment and kept Eli away from the unstable covering.
The initial findings suggested that Grandpa's collection channel still existed.
It wasn't large.
It wasn't a hidden river.
It was a narrow, partly obstructed system built to manage the slow movement of water through the ground.
Some sections were damaged.
Others were filled with sediment.
And one old line appeared to lead toward a covered storage chamber near the former orchard.
Eli stared at the map.
Then looked toward the garden.
“Could it be helping the watermelons?”
Nora nodded.
“Very possibly. But that doesn't mean we should start drawing more water out of it.”
Eli frowned.
“Why?”
“Because the source is limited. Your plants may be benefiting from moisture moving naturally through the soil. If we change the system without understanding it, we could make things worse.”
He considered that.
Then asked, “Can we fix the old channel?”
