Your starting point: a map full of possibilities.
A little exploring goes a long way

Three steps to your next trip.

01

Find a lake that
catches your eye.

Search by name or explore straight from the map. Looking for a particular fish? Use the species filter to discover matching waters.

Search a name, select a lake, and start exploring.
02

Get to know
the water.

Open a lake profile to explore recorded species, depth, water clarity, and its fishing zone. Available stocking records give you another piece of the picture.

Coverage varies by lake. A missing record does not mean a fish species is absent.

03

Make it a day
on the water.

Check available conditions and access information, then confirm the official rules for your destination. Star the lake for later, and use the catch log and waypoints to remember your trip.

Check the conditions

Weather, nearby water levels, sunrise and sunset, and solunar times add context to your plans.

Live conditions require a connection. Solunar times are a planning aid, not a catch prediction.

Remember the good spots

Save favourites, record catches, and add named waypoints. Export your saved information from the map.

Early starts welcome

A view for every part of the day.

Automatic dark mode follows your device’s appearance setting, giving the map a darker palette when you prefer it.

Take it with you

Get ready before you lose signal.

Add the map to your home screen for easy access. Prepare your lakes while connected, then check what’s available offline on your device.

Before you head out

Let the map and your chosen lake details finish loading. Star the lakes you want to revisit, then test them with your device offline before relying on them away from a connection.

Available when saved

Useful information offline

  • Starred lake snapshots and locally saved catches and waypoints.
  • Previously loaded information that remains in the browser cache.
  • Basic lake information from the downloaded lake index.

Saved detail depends on what loaded successfully. Map backgrounds only cover cached areas and zoom levels. Clearing browser data or storage eviction can remove saved information.

Requires a connection

Fresh information & syncing

  • Live weather and water-level updates.
  • New map tiles and information not already saved.
  • Account syncing and checking the latest official sources.

Offline records are saved copies. Reconnect to refresh information, and confirm current regulations before your trip.
