Top 4 Features

The X-Ray View — See What’s Under the Water

Lake Genius’s signature feature. Zoom into any area of the lake and a simulated X-Ray View reveals the underwater terrain beneath the surface — rocks, ledges, and hazards within 9 feet of the waterline. Updated daily, so you’re always seeing today’s conditions. No other boating app does this for the lakes we cover.

Daily Water Levels

Water levels change constantly, and what was safe last month might not be safe today. Lake Genius tracks water levels daily and displays the current shoreline in red on your map. Tap the water level button to see the exact reading in feet or meters.

Offline Maps — Works Where Cell Service Doesn’t

Most of the lakes we cover have limited or zero cell service once you’re on the water. Download your maps before you go and the app works fully offline — X-Ray View, POI markers, saved routes, and more. No signal needed.

2,000+ Curated Points of Interest

Marinas, fuel docks, slot canyons, petroglyphs, hiking trailheads, swimming spots, fishing locations, and more — all curated by the Lake Genius team. Not crowdsourced, not user-generated. Our markers are vetted by people who know these lakes.

LAKES WE COVER

See It in Action on the Lakes We Cover

Every feature in Lake Genius is built around the specific conditions, hazards, and destinations of the lakes we cover. More lakes are being added! Here’s where you can use the app today.

Lake Powell

Ninety-six canyons, 2,000 miles of shoreline, and constantly shifting water levels. Lake Powell is where the X-Ray View matters most. Explore the full Lake Powell experience.

Lake Mead

Well-documented water level changes have reshaped the underwater landscape. Hazards that were deep underwater years ago now sit near the surface. See what Lake Genius offers at Lake Mead.

Bear Lake

Smaller and calmer, but the turquoise water and family-friendly beaches draw boaters all summer. Lake Genius covers underwater terrain, POI, and trip planning here too.

Lake Tahoe

Over 1,600 feet deep in places, with underwater terrain that changes fast near shore. Tahoe straddles the California-Nevada border and draws boaters year-round. Lake Genius maps both sides with the X-Ray View, comprehensive points of interest, and daily water level tracking.

Lake Roosevelt

The longest lake in Washington stretches 150 miles behind Grand Coulee Dam, with remote arms and canyons that see very little traffic and almost no cell coverage. Lake Genius provides comprehensive POI, offline maps, and daily hazard updates built for boaters well beyond the main channel.

Lake Pleasant

Phoenix boaters know the drill — summer heat means water levels that move fast, and what was deep last weekend might not be next. Lake Genius tracks Lake Pleasant daily with the X-Ray View, comprehensive POI, and offline-ready maps.

More lakes are on the way. Download the app and you’ll get access to new lake coverage as it’s released — no additional cost.

TESTIMONIALS

What Boaters Are Saying

We’ve taken several family houseboat trips to the lake in years past. We normally relied on maps.

I was happy to find an affordable electronic option when I learned of Lake Genius, so downloaded it and subscribed prior to our trip in mid-October 2025. Looking at the app at home I was impressed with the amount of detail concerning elevations and landmarks. In use on the lake, I had a hard time finding a zoom level that would show me both buoy locations and enough elevation / depth information to be useful while underway, but recent updates have fixed that. We found the app very useful overall and a great value.

Rarely do I leave reviews on apps, but this is an absolute must have in Lake Powell!!

Thank you for an awesome app to help with boating —especially with Lake Powell newbies like us. Heck, even my long time Lake Powell buddies thought this was amazing.

This app is awesome!

Such a great way to spot underwater hazards easily on your phone. Saves you a lot of hassle and money from hitting your prop on a rock!
