Lake Genius — Enjoy Smarter, Safer Boating on Our Country's Greatest Lakes
The boating app that shows you what’s under the water. Lake Genius updates underwater hazards and water levels daily, maps 2,000+ points of interest, and works offline — even where you have zero cell service.
The Problem
Underwater Hazards You Can’t See. Water Levels That Change Daily.
Every year, boaters at Lake Powell, Lake Mead, and Bear Lake deal with $5,000–$20,000 in damage from hitting submerged rocks and hazards they never saw coming. Water levels shift constantly, exposing new obstacles that weren’t there last season. And most of these lakes have little to no cell service when you need help most.
Lake Genius was built to solve exactly that.
$10,000
Average cost of damage from a single submerged hazard hit. Rocks you never knew were there.
Daily Updates
How often Lake Genius updates hazard data and water levels. Not weekly. Not seasonally. Daily.
Offline Maps
Cell signal can be spotty at best when you’re on the water.
Core Features
Everything You Need on the Water
The X-Ray View — See What’s Under the Water
Our signature feature. As you zoom in, a simulated X-Ray View reveals the underwater terrain beneath your boat — including hazards within 9 feet of the surface. Updated daily. No other boating app does this for these lakes.
Daily Water Level Updates
Water levels at Lake Powell and Lake Mead change constantly. Lake Genius tracks them daily and highlights the current shoreline in red on your map, so you always know where the water ends and the hazards begin.
2,000+ Points of Interest
Marinas, fuel docks, slot canyons, petroglyphs, beaches, hiking trailheads, fishing spots, and more. Every marker is curated by our team — not crowdsourced. Tap any point of interest to get details and navigate there.
Works Offline — Even at Lake Powell
Most of Lake Powell has zero cell service. Download your maps before you leave home and every core feature works offline — hazard detection, navigation, points of interest, route tracking, and saved markers.
MULTIPLE LAKES
One App
Lake Powell
96 canyons. 2,000 miles of shoreline. The most dramatic water level changes of any lake we cover. Lake Powell is where the X-Ray View matters most — and where cell service is most challenging. Download your maps before you launch.
Lake Mead
Just 30 minutes from Las Vegas. Lake Mead’s well-documented water level changes have reshaped the underwater landscape, making daily hazard updates essential for every trip. Whether you’re launching from Callville Bay or heading to Cottonwood Cove, Lake Genius has you covered.
Bear Lake
The Caribbean of the Rockies. Bear Lake’s turquoise water and family-friendly beaches make it one of Utah and Idaho’s favorite summer destinations. Lake Genius maps every beach, marina, boat ramp, campground, and fishing spot so you spend your time enjoying the lake — not searching for what’s where.
Lake Tahoe
Crystal-clear water and steep underwater drop-offs make Lake Tahoe as demanding as it is beautiful. Lake Genius maps marinas, beaches, and hazard zones across the California-Nevada border so you can explore all 72 miles of shoreline with confidence.
Lake Roosevelt
One hundred and fifty miles of reservoir winding through Eastern Washington’s canyon country — and most of it without cell service. Lake Genius gives you offline maps, comprehensive points of interest, and daily underwater hazard updates so you can navigate the full length of the lake without guessing.
Lake Pleasant
Just 45 minutes from downtown Phoenix, Lake Pleasant is the desert’s go-to weekend escape. Water levels move with the Arizona heat, and Lake Genius tracks every change daily — so whether you’re pulling into Scorpion Bay or anchoring in a quiet cove, you know what’s beneath you.
