Clues to assist in solving the Mystery of Caddo Lake (spoilers):
Three related characters all suffer from the same abnormality. Each may also travel forward and/or backward in time, coinciding with seizures or tremors and temporary deafness.
Their capability is only triggered when the water in the lake is very low.
The characters struggle to recognize the connection between their physical symptoms and time travel, much less control the ability or avoid it.
The main characters’ actions seem to be occurring simultaneously but will be found to have happened days, years, or even decades apart. Some of these events even happen in the exact same place.
Cee, Celeste, and Ellie’s mother are the same person (she does not travel in time).
The dam on the lake provides clues to a linear interpretation of the story. It was built new in one era, modified with a road across it in a later time, and deteriorated to the point of failure almost two decades later.
The sound of search helicopters overhead is only present in the latest era (2022).
The daylight, or lack thereof, often changes as characters step from one era into another.
The appearance of rare moths and wolves indicates the character has stumbled into a past era.
