But by the time Eliza was born, parts of the system were already deteriorating.
The northern supply line had become unreliable.
Several gates were closed.
Other structures were abandoned.
Then, during a particularly dry summer when Eliza was eight, water stopped reaching the Hart property through the old ditch altogether.
Samuel tried to repair it.
He cleaned sections of the channel.
Examined old maps.
And paid contractors to inspect several accessible structures.
But the water never returned in a useful, dependable flow.
The neighboring farms eventually installed modern wells and pumps.
Some became larger.
Others were absorbed into commercial agricultural operations.
Samuel couldn't afford the same equipment.
He relied on rainfall and limited supplemental irrigation where possible.
As the years passed, the farm became less productive.
Samuel borrowed money for seed.
Then fertilizer.
Then repairs.
During good seasons, he repaid enough to continue.
During bad seasons, the debt grew.
And every autumn seemed to end with the same conversation.
Perhaps next year would be better.
Eliza grew up hearing those conversations through the kitchen doorway.
Her father tried to keep the worst financial worries away from her.
But children noticed things.
She noticed when the old truck remained unrepaired for another month.
When her mother began shopping only from the discount shelves.
And when Samuel came inside after sunset looking as though he'd aged ten years during the afternoon.
Eliza's mother died when she was sixteen.
A sudden illness took her after a difficult hospitalization.
The loss changed the household.
For months, Samuel barely spoke at dinner.
He continued working because the cotton still needed attention, the bills still arrived, and his daughter still needed a home.
Eliza helped however she could.
She learned to drive the tractor.
Repair basic irrigation fittings.
Check equipment.
And distinguish healthy cotton from plants struggling with heat, pests, or insufficient water.
She wasn't interested in becoming a farmer at first.
She wanted to study agricultural engineering.
Perhaps work with irrigation systems.
Find a job that paid reliably.
And help her father without spending every summer worried about whether rain would come.
Samuel encouraged her.
He told her to leave.
To study.
To see more of the world than the hundred acres around their farmhouse.
But money was scarce.
So Eliza attended a nearby community college for two years while working part-time.
She studied agricultural technology and water-management fundamentals, then returned home when Samuel's health began declining.
By twenty-five, she was running much of the farm.
By twenty-seven, she was managing it alone.
Samuel's final season was particularly difficult.
An early summer drought weakened the cotton.
The old tractor required expensive repairs.
A supply bill arrived with an interest charge Eliza hadn't expected.
Then Samuel suffered a severe stroke in October.
He survived the initial emergency but never fully recovered.
During the following months, Eliza spent mornings checking the farm and afternoons visiting him.
Sometimes he recognized her immediately.
Other times, he seemed confused.
But whenever they discussed the old irrigation ditch, something changed in his expression.
