How Fly Findr worksreal reports, real sources.

    Every recommendation comes from real fishing data, never guesswork. Here's exactly how the pipeline works.
    1. 01

      Gather reports

      We collect fishing reports from fly shops, guide services and regional report services in every state we cover. Sources are vetted for reliability, and new ones are added as we expand.

    2. 02

      Read the signals

      An AI model reads each report and pulls out the facts: flies mentioned, hatches, water conditions, techniques and specific places. Each signal links back to its source.

    3. 03

      Pick the flies

      Signals are matched to specific waters and access points, then turned into fly picks scored for how strongly the data backs them, each with a plain-English reason.

    4. 04

      Write the bite report

      From the same signals we write a weekly bite report for each water: conditions, hatches, what's working and what to expect, with every source cited.

    Confidence scores

    Every pick gets a 0 to 100 score for how strongly the available data supports it.

    90 to 100Very highStrong agreement across several recent reports from reliable sources.
    70 to 89HighA good signal from at least one reliable source, with supporting data.
    50 to 69ModerateSome signal, but fewer data points or older reports.
    Below 50Not publishedNot enough data to make a reliable pick.

    Scores are relative within a location. A 90 on the Henry's Fork and a 90 on the Farmington both mean "strong signal", but they reflect different local report pools.

    "Weekly" covers a rolling 7-day window ending the previous Saturday. The pipeline runs in stages overnight Sunday.

    Known limits

    • Coverage varies by state. Western states (ID, MT, CO, OR, WY) have the most data. The East and South are growing.
    • Seasonal transitions lag. Ice-off, runoff peaks and closures may not show up right away.
    • Sparse waters run older. Places with few reports may show older picks until more data comes in.
    • Scores are relative. Compare picks within a water, not across different waters.
    • Not a substitute for local knowledge. Check with a local fly shop and confirm current regulations.

    Data sources

    The engine draws from three streams.

    Fishing reportsFrom fly shops, guides and regional report services, each vetted for accuracy and coverage.
    USGS flowsReal-time stream flow from USGS gauges, charted on each water's page.
    WeatherCurrent temperature, wind, precipitation and pressure for every location.
