Every number here is a base rate from this source’s own report history — how the read is built.
Likely flowing well
As of 2026-10-30 · 90d rain = 19.50″ · nearest historical analogs averaged 0.84 (Strong)
Driven by recent rain: the last 90 days predict it better than any longer window (strongly). It turns on fast after storms and off just as fast, and it is dry 32% of the time.
Thin evidence. 19 reports is above the 10 needed for a read, but under 25 the engine flags the evidence as thin. Treat this as weak — suggestive, not solid.

Rain and season are entangled — more reports get filed in cool, wet months. The season-controlled column removes that day-of-year cycle, so it is the trustworthy one. A big gap between the two columns means a correlation was mostly calendar, not rainfall. survives -> genuine rain response
Average flow by month
Dashed = no reports that month, which is not the same as dry.
