Frequently asked questions

IdentaFly is built for fly fishers who want to prepare to fish a place—a local day trip or somewhere out of state—with less guesswork. The product combines a searchable fly and species database, location-based hatch forecasts, waters with real-time river conditions (where available), public land context on the map, image recognition fly photo identification, and a fishing journal so you can learn what worked and when.

The mobile apps and this website share the same mission: help you connect what is on the water to what is in your fly box.

The mobile apps are optimized for on-stream use—camera identification, journaling in the field, location-aware hatch, favorite gages, and the home-screen gage widget. The website emphasizes discovery—species, patterns, hatch planning, and waters—plus tools like scan where we ship them. Use both together if you like.

Waters are rivers and streams we list so you can browse by state, open a location, and see details that matter for planning—hatch-related context, USGS gages and conditions where available, photos, and stream reports when anglers or shops share them.

Start from Fly fishing waters by state and drill into a specific water for more detail. From a water page you can often jump into the hatch forecast for that place.

These metrics help you read what the river is doing on a given day:

• Temperature — How warm or cold the water is. Many aquatic insects and trout activity track comfortable thermal ranges; extremes can slow or shift feeding.
• Discharge (flow) — How much water is moving through the gauge site, often in cubic feet per second (cfs). Big jumps can mean runoff or dam releases; very low flows can change holding water and clarity.
• Turbidity — How cloudy or clear the water is from suspended sediment. It affects how fish see your fly and where they hold.

When we show gauge-based readings, they often come from public sources such as U.S. Geological Survey (USGS) water data. Conditions are a piece of the puzzle—always pair them with local knowledge and safe wading judgment.

Favorite gages let you pin USGS (and similar) stations you care about so you can check flow (cfs) and temperature quickly from Waters or the hatch map.

On mobile, IdentaFly also offers a home-screen water gage widget (subscription) that shows CFS and temperature for your top stations without opening the app. Add it from your phone’s widget picker—search for “IdentaFly.”

Shops and partners embedding conditions on a website should see our separate LocationWidget setup docs (WordPress, Squarespace, or custom HTML).

Where shown, many gauge-style readings are aggregated from public sources such as USGS. Availability varies by station and maintenance; we surface what we can for planning, but you should always verify time-sensitive flows and safety before wading or boating.

The hatch forecast combines species lifecycle information with where and when you are fishing (or a region you select) to surface what is likely relevant for that window. It is a planning aid—not a guarantee—because real hatches move with weather, flow, and local quirks.

Use it to narrow down what to research, which flies to pack, and what to watch for on the water. Pick a place on the map (search, GPS, or a saved favorite), then use the results sheet for month, weather/temp context, and species groups.

Bug activity and fish behavior respond to temperature, flow, and clarity. The forecast is more useful when it can sit alongside current river conditions (where we have them), because “on paper” timing and what you see at the gauge the same week can tell a fuller story.

That is why IdentaFly emphasizes conditions next to hatch timing: it helps you connect calendar expectations to what the river is actually doing.

Yes—your field notes help us improve. When something looks off for your water or week, use the in-app feedback paths tied to the hatch experience (where available) so we can triage and tune models and copy over time.

Public Land is a map overlay on the hatch forecast that shows approximate land management categories—such as federal, state, local, and other—based on USGS PAD-US (Protected Areas Database of the United States).

On the website it is available with an IdentaFly subscription. Turn it on from the Public Land control on the hatch map, then use the legend to read the color bands.

It is for trip-planning context, not a guarantee you can fish a stretch of water.

No. Boundaries are approximate and for planning only—not for navigation or legal boundary determination. The overlay shows land management, not water-access rights. Unshaded areas are generally private or unmapped public land—not a guarantee of access.

Always verify access locally (regulations, landowner rules, and on-the-ground conditions) before fishing.

Open Fly pattern recognition on the web (or the camera flow in the mobile app), take a clear, well-lit photo of a single fly, and review the top matches. You will see pattern suggestions tied to our database and lifecycle context where we have it.

Tips for better matches:

• Fill the frame with the fly; avoid heavy digital zoom.
• Prefer even light and a simple background.
• Show the profile or top that best displays silhouette and materials.

Yes—with caveats. Recognition depends on photo quality, angle, lighting, and whether the pattern exists in our database. As more anglers use IdentaFly and we expand coverage, results improve—but like any angler, the system will occasionally miss or mislabel. When that happens, try another photo or browse species search and patterns manually.

Common reasons include:

• The photo was dark, blurry, or the fly was too small in frame.
• The pattern is not in our database yet, or it is visually close to several patterns.
• A temporary model or network hiccup.

Try again with a clearer macro-style shot, then search for the pattern or species. If you are in the app, you can often submit a fly so we can grow the library.

Not yet. The goal is to help you learn your fly box and connect patterns to the insects they imitate. Coverage grows with community submissions and curation—search first, then submit what you are missing when the app allows it.

Species are the insects (and related life) you may encounter on the water. Patterns are the artificial flies that imitate them.

Use search to browse either side of that relationship. Hatch results and pattern or species detail pages often link between them so you can go from “what’s hatching” to “what to tie on.”

The Digital Flybox (mobile, premium) stores favorited patterns in named boxes so you can organize what you carry or want to tie. Heart a pattern from search or scan results, then manage boxes from the app’s Flybox entry (Quick Start or Profile).

It is intentionally secondary to trip-prep tools like hatch, waters, and conditions—but useful once you know what you want in the box.

A journal turns one-off trips into memory you can search: what flew, what fly worked, flows, weather, and notes you will not trust to recall next season. IdentaFly is built so those details sit next to species and pattern context—helping you pattern-match your own fishing over time.

Capture where you were, when (date and rough time of day), what you saw on the water, which fly and size, and how you presented it. Over time, those fields become your personal hatch and tactics archive—far more useful than “great day” with no specifics.

In the mobile journal, Want to go lets you bookmark a spot for a future trip without building a full itinerary. Think of it as a lightweight wishlist—saved places you intend to fish—sitting alongside catches you have already logged.

Stream reports summarize recent fishing-related information for a water—conditions, hatches, and local notes when we have them—so you can research a destination before you go. They complement (but do not replace) live gauges, the hatch forecast, and your own eyes on the water.

Open a water from Waters and look for a stream report when one is available. Conditions change fast; treat reports as a snapshot, not a guarantee.

Yes. Stream reports reflect information we have gathered; conditions change fast. Use report feedback where we offer it so we can address spam, mistakes, or abuse, and keep the signal high for everyone.

Features like nearby hatch outlook need a coarse location to be useful. We use location to personalize results—not to sell your precise fishing spots. For exact practices, see our privacy policy.

Most live features need a network—fly recognition, fresh hatch forecasts, river conditions, and map overlays all rely on connectivity at some point.

On mobile, you can often capture a photo offline and upload or scan it when you are back in coverage. Limited offline support is part of the free tier comparison in-app; exact behavior can vary by build. Do not rely on the app alone for navigation or safety when you are out of service.

IdentaFly is freemium: you can use core parts of the product without subscribing, including scoped species and pattern discovery (for example mayfly-focused search), GPS-based hatch charts, and limited offline support—see the in-app or web feature comparison for the exact list.

Full access unlocks premium capabilities such as AI fly photo identification, searching the full species and pattern libraries, the digital flybox, the complete hatch forecast, public land on the hatch map, and mobile extras like the gage widget—features that depend on heavier cloud and data infrastructure.
