SHOULD YOU FISH TODAY?

An active weather alert matters more than the fishing score

Check the active National Weather Service alert before deciding whether to go. The derived fishing score should not override official safety information.

River flow1,260 cfs

Current streamflow is 1,260 cfs. Flow is falling by about 2% over 24 hours.

Wind0 mph

Wind should be relatively manageable for most fishing logistics.

Water temperature40.1°F

This reading becomes biologically useful only when paired with a species that is actually confirmed for this water. The site no longer turns temperature compatibility into an unverified species claim.

What we still don't know
  • 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.

WHAT CHANGED

Current score drivers

  • Streamflow is down 2% versus roughly 24 hours ago.
  • Current wind is about 0 mph.
  • Current precipitation probability is 0%.
  • An active NWS alert is reducing the planning score.

7-DAY PLANNING OUTLOOK

Weather-based trip planning

Tue59/10048–51°F · wind up to 5 mph
Wed52/10046–49°F · wind up to 10 mph
Thu52/10045–48°F · wind up to 5 mph
Fri45/10045–47°F · wind up to 15 mph
Sat45/10045–47°F · wind up to 15 mph
Sun52/10044–46°F · wind up to 10 mph
Mon52/10043–45°F · wind up to 10 mph

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.

SPECIES INTELLIGENCE

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.

TRANSPARENCY

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.
