A useful starting point
Surface movement can be recorded without deciding what lies beneath it. Write where you saw ripples, reflections or a change in visible texture. Wind, light and the viewing angle may alter the impression. A shore note is not evidence of depth, current strength or a safe place to enter the water.
Try this sequence
- Choose a fixed lawful viewpoint
- Describe only the visible surface
- Record wind and light separately
- Leave underwater explanations as unanswered questions
A small worked example
One patch of water may look dark because a tree is reflected in it. Write “dark reflection beside the visible bank” rather than “deep pool”. The first describes the image; the second claims information the surface view has not established.
What to keep in your notes
Afterwards, write down the detail that changed your decision and the information you still need. Use the record on a later date as a question list, not as a current assessment of the place. A short, accurate note is easier to revisit than an unsupported conclusion.
