Fortymile R Fishing Conditions
Updated 2 hours ago · 1 attached data sensor
Today and tomorrow look broadly similar
Today is 86/100 and tomorrow is 81/100. The difference is too small to justify postponing solely because of the forecast. The tomorrow comparison changes forecast weather while carrying forward the latest measured water context, so recheck the gauge or tide before leaving.
Current streamflow is 1,580 cfs. Flow is falling by about 2% over 24 hours.
Wind should be relatively manageable for most fishing logistics.
- No authoritative species evidence is attached yet, so this page deliberately does not recommend specific fish species.
- No qualified multi-year monthly flow baseline is available yet, so the current flow cannot be labeled high or low for the season.
Current score drivers
- Streamflow is down 2% versus roughly 24 hours ago.
- Current wind is about 0 mph.
- Current precipitation probability is 57%.

Weather-based trip planning
Future scores primarily reflect forecast weather while using today's water conditions as the baseline. Recheck before the trip because river flow, tides and water temperature can change.
Confirmed fish targets
No authoritative species occurrence evidence is attached to this water yet, so the site deliberately does not recommend trout, bass or any other target merely because the temperature looks compatible.
Species recommendations require stored authoritative/editor-confirmed occurrence evidence. Broad temperature compatibility is not enough.
Useful starting points
Multi-weight jig assortment
Multiple weights let you adjust to current speed and depth.

What this score means
This is a planning score based on measurable conditions. It is not a bite forecast and cannot guarantee catches. Missing facts are left unavailable rather than invented.
