How this site decides what it can and cannot say — the method.
Insufficient record
No read issued
4 reports — a correlation needs at least 10 before it means anything, so no read is issued here.
What people saw
4 observations between 2022-01-14 and 2025-03-21, every one strong. The most recent was 18 months ago.
These are the observations themselves, not a forecast. Too few to correlate against rainfall, but they are what people actually found.
- 2025-03-21Strong0.8Waterfall was flowing, cave was dripping, catchment was overflowing. Plenty of water here.
- 2024-12-30Strong0.8Even with the ongoing dryness, the cave seep had a solid trickle and the trough outside was overflowing.
- 2023-11-04Strong0.8Solid, as usual.
- 2022-01-14Strong0.8Water in springbox and cave. Also, the drainage was flowing and there was a lil' waterfall.
Why
The engine will still produce a number from 4 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 4 reports, the engine's read would average all 4 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.
6 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.
7.59″ 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.
