01Watershed context

Understand the water.

A river is more than a blue line. See the terrain, tributaries, elevations, and surrounding geography that give each stretch its character.

  • Terrain and hydrology together
  • Watershed-scale orientation
  • Geography that explains the water
Mountain terrain with contour lines, streams, lakes, and wilderness boundaries

02Species in place

Built for western trout.

Native trout deserve more than a generic map layer. Explore species and cutthroat regions with conservation-aware context and careful boundaries.

  • Native range context
  • Cutthroat region orientation
  • Careful conservation language

  • Flow and weather at a glance
  • Fish and fly context
  • Details shaped for field use

  1. 01

    Plan

    Read the water before you leave. Terrain, access context, weather, and flow live in one place.

  2. 02

    Fish

    Carry the details that matter into the field without turning the day into a dashboard.

  3. 03

    Remember

    Keep useful observations close and build a personal record of water over time.

05Product philosophy

Privacy-first
by design.

Time outside should not require giving up unnecessary personal context. Cutthroat Atlas is being built with restraint, transparency, and respect for the places people choose to remember.

Useful first

Product decisions begin with what is genuinely helpful on the water.

Personal context stays personal

Trip planning and field notes are treated as information worth protecting.

Privacy choices should be clear

Privacy controls should be understandable, deliberate, and easy to find.

06The starting watershed

Built in Colorado.
Expanding West.

Colorado is where Cutthroat Atlas begins. From here, the Atlas will grow across western trout country.
