LakeLensComing soon

How it works

Lake level in. Hazard paint out.

Five steps. One formula. Planning only — not a navigational aid.

Coming soon to iOS and Android

    Level

    Read the lake.

    LakeLens pulls a public water-surface elevation when you are online. Override it to walk a lower week before you launch. The number you are using stays on screen.

    Bed

    Load a pack.

    Each pack is a cropped piece of public-domain bed elevation. Powell ships as eight regions from Last Chance through Rock Creek. You download the water you boat, not the whole reservoir.

    Paint

    See depth and hazards.

    Depth is water elevation minus bed elevation, same vertical datum. Hazard view paints the bands. Zoom in and fill and isolines appear. Zoom out and they leave.

    Plan

    Pick the day.

    Places, ramps, weather, and a measure line sit on the same map. Draw a run. See a dry-leg warning if the math says that stretch is out of water.

    Go

    Take it offline.

    Packs, last lake level, cached weather, and saved places stay on the device. The canyon will eat your radio. The map should not go with it.

Then it is your call.

Eyes on the water. Official charts when they apply. LakeLens is a planning overlay, not the helm.
