Offline depth navigation · Lake Powell

Know Before You Go.

Preview the whole lake before you leave the dock — every shallow and every arm, mapped at today's water level. See what's beneath you before you're floating over it.

The app

Depth you can trust at a glance.

Wayvz reads one number a day — the lake level — and recolors the whole map around it. No downloads on the water, no clutter, no guesswork about what's below.

Depth X-ray

Every foot of lakebed, colored by how much water sits over it right now. Deep reads calm and gray; shallow warms toward amber and red.

depth = level − lakebed

Fully offline

The lakebed ships inside the app as vector tiles. Out on the water with no signal, the map still knows exactly where the bottom is.

Level-aware

Lake Powell rises and falls. Wayvz pulls the day's official level and recolors the shoreline to match — the map is current, not a snapshot.

Why Wayvz

Clarity on the water. Nothing extra.

Most chartplotters bury depth under menus, layers, and clutter. Wayvz does one thing well: it shows you how much water is under the boat, honestly, and gets out of the way.

Built by a solo studio for boaters who'd rather glance than squint.

Depth estimates are supplemental — always stay in control of your boat and never rely on the map to avoid hazards.
