Know what the river's doing before you drive to it. Cutty pairs real-time USGS flow and water temp with hatch charts, fly patterns that match the bug, and the public access to reach the water.
※ Stream Intelligence
- Real-time flow and water temperature from USGS gauges
- Daily flow and temperature history, a week back and further
- NOAA weather — wind, cloud cover, barometric pressure, forecast
- NOAA tide stations for the coast and estuary
※ Hatches & Entomology
- Species-level hatch timing for mayflies, caddis, stoneflies, midges, and terrestrials
- Emergence predictions from local water temperature and degree-day accumulation
- Reference pages for every organism — life cycle, habitat, distribution, flies that imitate it
- Hand-curated hatch data on named waters including Penns, Letort, Firehole, Beaverhead, Frying Pan, Gallatin, Green River, Lehigh, and Esopus
※ Fly Patterns & Tying
- Pattern pages include full recipes — hook, thread, body, hackle, wing, dubbing, tying notes
- Coverage across trout, bass, steelhead, salmon, and saltwater
- Patterns linked to the bugs they imitate, so matching the hatch is one tap
※ The Map
- Every named water we could find, drawn over USGS flowlines
- Public land boundaries — BLM, USFS, National Parks, state wildlife areas
- Fly shops with hours, phone, and directions
- Federal campgrounds, trailheads, and boat launches from Recreation.gov
- State-by-state fishing access points, boat launches, and parking
- Waypoints for the runs, holes, and put-ins you want to remember
※ Fishing Guides
- Directory of guides by state and water
- Trip types, rates, and direct contact
※ Offline Maps
- Save regions for when you're out of service
- Map tiles, water bodies, and access points travel with you
※ Data Sources
Cutty surfaces public data from USGS, NOAA, the National Hydrography Dataset, PAD-US public land boundaries, Recreation.gov, and state wildlife agencies. Tap any value and the source is one link away. Cutty is not affiliated with or endorsed by any government agency; .gov links point to public data sources for reference.
