"Probably."
"USDA records?"
"Maybe."
"Drainage district maps?"
"At the county office, if they haven't lost them."
Renata smiled. "They haven't. They just haven't found them yet."
She spent the rest of the day taking elevations, inspecting the new outlet, tracing old swales, and examining culverts. She used a level and GPS equipment to map the grade through the altered channel. At several points she asked Casey for exact dates corresponding with photographs, rainfall readings, and water-depth measurements.
Casey had them.
Renata looked impressed but did not praise her excessively. "This is useful because you recorded the boring days too."
"Harlon said boring survives cross-examination."
"Harlon's right."
They worked for hours beneath the summer heat. Renata eventually stood beside the new concrete outlet, looking down the line of flow toward Warren's land.
"I can already tell you this outlet concentrates water more than the old surface pattern did," she said. "What I can't tell you today is how much difference that made under comparable storms. I need rainfall history, pre-project topography, design drawings, and if possible the model they used for permitting."
"What if they won't give you the model?" Warren asked.
"Then Harlon asks through the process available to him. If this becomes litigation, there are stronger tools."
"And if the design says it's fine?"
"Then we test whether reality agreed with the design."
Warren liked that answer.
The next several weeks became an exercise in reconstructing a landscape that no longer existed. Casey searched through old farm files. Warren climbed into the attic and brought down boxes he had not opened since his wife died. They found photographs from the 1970s showing cattle on the low ground before it was converted entirely to row crops, photographs from the 1980s after Warren deepened a ditch, and one black-and-white picture of Warren's father standing beside a shallow sheet of spring water with ducks visible in the background.
On the back, in faded pencil, someone had written: low flat after March rain, 1959.
Odell studied the photograph for a long time.
"This matters," he said.
"Why?" Warren asked. "It proves the place got wet sometimes. I could've told you that."
"Because the question isn't whether somebody manufactured a wetland out of a soybean field in one season. The question is whether agricultural drainage and grading converted or suppressed a historically wet landscape, and whether a restoration project can lawfully restore functions that existed before intensive farming. This helps establish context."
County records added more. Soil surveys classified much of the low acreage in a series known for seasonal wetness. Historic aerial imagery showed a faint dark band through the field in years when surrounding ground was dry. An older topographic map suggested a broad shallow depression connected to what had once been a seasonal wet corridor before drainage improvements and field leveling simplified the surface.
None of those records alone proved a mitigation project. Together they changed the story.
