How this site decides what it can and cannot say — the method.
Insufficient record
No read issued
3 reports — a correlation needs at least 10 before it means anything, so no read is issued here.
What people saw
3 observations between 2017-09-01 and 2018-09-03, every one pools or dripping. The most recent was 8 years ago.
These are the observations themselves, not a forecast. Too few to correlate against rainfall, but they are what people actually found.
- 2018-09-03Pools or dripping0.2Murky, unpleasant taste and odor. Probably the worst I've seen it.
- 2018-06-09Pools or dripping0.2Cement trough was 3/4 full of green, stagnant water. Taste was hard to get past.
- 2017-09-01Pools or dripping0.2Some trickle along creek, cement trough was full (and quite green).
Why
The engine will still produce a number from 3 reports, and that number is noise. It will happily report a perfect correlation from two observations. On a screen where someone is deciding how much water to carry, that is the most dangerous thing this site could render, so it is not rendered.
With 3 reports, the engine's read would average all 3 of them rather than the ones whose rainfall matched today — so it would return the same figure on every date of the year, whatever the weather had done. It is a summary of the record, not a forecast.
7 more reports would reach the 10 needed for a read.
Rainfall here
The last 60 days here have been wetter than usual for mid September — 84th percentile against 19 years of rainfall at this coordinate, through 2026-09-15.
This is rainfall, not water. It says what the weather has done here, not what is in the ground — a spring fed from deep water can run through a dry autumn, and a runoff channel can be empty two weeks after a wet one. Which of those this is takes reports to find out.
5.42″ over 60 days, against 19 years at this coordinate. Band: wetter.
This is the fix
Every dated observation moves this source closer to a read, and sharpens the ones around it too.
