01
Observe
Log the location, then answer six plain-language cues covering clarity, smell, surface, wildlife, rain and nearby outlets.
The One Health reading
One location. Six observations. One honest snapshot.
Read the stream.Not the jargon.
Stand at the water’s edge and tell Lens what you can see, smell and hear. It cross-checks your observations, explains anything unusual, and turns them into a simple Stream Health Score.

“A stream tells you plenty before a test kit ever comes out.”
Start at the bank: can you still see the bottom?
A check that shows its working.
Every score deduction is named in the final result. When two observations clash, the person at the water decides what is true—Lens only points out what deserves another look.
02
Cross-check
Eight ecological checks compare water, air, surface, wildlife and recent rain before the score is made. Keep an answer or recheck it; that decision appears in the report.
03
Act
Read every deduction, confidence note and One Health next step—without mistaking a field check for a lab test.
