Tip Tap any colored pin to open details about that location and its planning links.
Getting started
01
Click a large pin to open detailed information about that water.
02
Scroll inside the pop-up to see stream details, links, hatches, access notes, and fishing conditions.
03
Use the map controls to zoom, search, measure distance, and change base layers.
04
Use full-screen mode for better viewing.
02READ THE WATER
Superhatch levels
Three simple classifications describe the frequency and importance of surface hatch activity.
I
Level 1
Limited or inconsistent surface hatches.
II
Level 2
Good hatch activity, but usually timing-specific or section-specific.
III
Level 3
Strong hatch-driven water where insect activity can bring trout consistently to the surface.
03OPEN A PIN
The pop-up window
The hub for stream information, planning links, coordinates, and safety notes.
Tap or click any fishing pin to open its information window. Each pop-up provides location coordinates, useful planning tools, and available information about the selected trout water.
Google Maps Area View
Opens the selected pin's location in Google Maps for geographic reference, nearby roads, access planning, and navigation.
Windy.com Weather & Radar
Opens Windy.com for weather forecasts, radar, wind, and other conditions near the selected location.
USGS Regional Stream Data
Provides access to nearby USGS streamflow monitoring information, including river discharge, water levels, and water temperature where available. Monitoring stations may not be located directly on the selected water.
Interactive AI Hatch Finder
Uses the selected pin as the center of a 100-mile search radius to evaluate nearby trout waters for potential hatch activity, rising trout, and dry-fly fishing opportunities.
iOverlander Camping
Opens iOverlander to help locate nearby camping and overnight options. Use the displayed coordinates to refine your search.
Planning and safety information
Each pop-up includes a reminder to verify access, fishing regulations, and current conditions before visiting. Some pins identify potential access points rather than confirmed public access. A link to the full Superhatch Map terms is also provided.
Detailed trout-water information
Scroll down within the pop-up to explore additional fishing information. Larger trout-water pins may include Superhatch Level, water type, stream size, trout species, water descriptions, productive hatch locations, access notes, fishing conditions, and seasonal hatch charts.
✕
Close the pop-up by clicking the X in the upper-right corner or anywhere on the map.
04ACCESS & LAND
Land boundaries
Boundary lines are useful references—not legal access confirmations.
Boundaries are shown where available and are for general reference only. Always verify public access, private property, regulations, and current land status locally before entering an area.
Field tip
Enable the GPS location icon to compare your position with nearby boundaries.
05ACCESS & LAND
Map labels and access areas
Identify marked locations, but never assume a map label grants public access.
Some river pools, access areas, parking areas, trailheads, and landmarks are labeled on the map. Unnamed water points may display as Trout Water. This does not mean they are necessarily access points. Click any pin to open its pop-up for coordinates and planning links, including Google Maps, weather, streamflow, the Interactive AI Hatch Finder, and camping.
Access, parking, trail, and land-use conditions can change. Map locations may be approximate, outdated, or may not reflect current access restrictions, property boundaries, closures, or legal status. Always verify current conditions and legal access before visiting.
06MAP TOOLS
Choosing a map layer
Two complementary backgrounds help you study roads, trails, terrain, and water.
OpenStreetMap is useful for viewing roads, trails, and access areas. USGS Topo shows terrain, elevation contours, and topographic features. Use the Layers button to switch between the two backgrounds.
07MOBILE MAP TOOLS
GPS location and direction
Follow your location, pause automatic map tracking, and read the directional pointer.
01
Tap once — turn GPS on
Tap the GPS button once to turn on GPS, center the map on your current location, and automatically follow your movement. The blue circle shows your location, while its pointed tip indicates the direction the top of your phone faces. Hold your phone with its top pointing forward to see the direction you're facing.
02
Driving direction
When driving, the pointer uses GPS direction of travel, even when your phone is mounted horizontally. The pointer also maintains a steady direction during brief stops to prevent sudden changes.
03
Tap again — turn GPS off
Tap the GPS button again while the map is following you to turn GPS off.
04
Drag, recenter, and resume following
Drag the map to explore nearby areas. GPS remains on, and your location continues updating, but the map stops automatically following your movement. Tap the GPS button once to recenter your location and resume following. Tap it again while following to turn GPS off.
Tip: tap either GPS screenshot to open it over the guide. Use the zoom control in the viewer to read the small pop-up labels.
Location & direction accuracy
Allow location access when prompted. The pointer uses compass and GPS information to determine direction. If direction information is unreliable, only the blue location circle may appear. Location and direction accuracy can vary depending on your device, surroundings, and GPS or compass signal quality.
08ACCESS & LAND
Trail access to water
Use parking and trailhead pins alongside mapped paths to plan possible approaches.
Magenta pins indicate parking areas and trailheads.
On the OSM Base Layer, trails are often shown as thin red or dashed lines. Use them to identify possible hike-in routes from nearby roads and access areas to verify. Always verify public access, closures, and trail conditions before hiking in.
09TRIP PLANNING
Interactive AI Hatch Finder
Start at a map pin to explore trout-water opportunities within 100 miles.
100 MILES
One pin. Nearby hatch possibilities.
Choose any pin on the map to use as the center of the 100-mile search radius.
The Interactive AI Hatch Finder uses that location to evaluate trout waters within the search radius for hatch activity, rising trout, and dry-fly fishing. It compares streamflow, weather, seasonal hatch timing, and recent fishing conditions, then recommends up to three waters with suggested fishing sections, expected hatches, best dry-fly windows, approximate locations, and navigation links. You can also ask about flies, access, camping, alternate waters, or changing conditions.
The Interactive AI Hatch Finder opens in ChatGPT with the prompt automatically filled in. Send the prompt to generate your results. You may be asked to sign in to ChatGPT.
For more detailed Hatch Finder results, use a higher thinking-effort setting if your ChatGPT account offers one. Otherwise, send the prompt normally.
10MAP TOOLS
Distance measurement tool
Estimate stream lengths and walking routes before you head out.
Use the ruler icon to measure distances in yards or miles.
Useful for estimating hike-in routes, walking distances, and the length of stream sections.

Searching
Locate the river you want without manually scanning the entire map.
Use the search tool to find a water. Type the water name and a list of the waters with their state will display.

If multiple results appear, choose the result closest to the area you want to view.
12REGULATIONS
Special regulation sections
Orange lines help identify mapped upstream and downstream regulation boundaries.
Special regulation sections are identified by orange lines marking their upstream and downstream boundaries. Click or hover over a highlighted line to view regulation details.
Verify regulations before fishing
Always verify current fishing regulations with the appropriate fish and wildlife agency before fishing.
