Built from the last 7 days of daily mean air temperature (weighted toward recent days), a seasonal phase term, and coefficients fitted against 55 USGS gauges across 171,799 daily records; leave-one-station-out error is 1.96 °C. Large reservoir releases, spring-fed reaches, deep pools and tidal water can sit well outside this range. Water temperature tells you how actively fish are likely to feed — it does not tell you where they are. How this estimate works →
