Track lake levels around the clock.

Hyfi serves as a set of eyes where you need them. It all starts with reliable, high-resolution water level data.

  • $1495/monitor per year includes a water level sensor, custom dashboard, alerts, data storage, and dedicated data cleaning. If your sensor goes out, we will send you a new one in the mail, shipping included.

  • With the full service add on, Hyfi will survey your site, install the monitor for you, and handle any maintenance.

    Price depends on location and size of the network.

  • Struggling to make sense of your data? Or maybe you want to take your operations to the next level with bespoke digital solutions. Hyfi’s team of water engineers and computer scientists are ready to help!

Data at your fingertips, no matter where you are.

Hyfi sensors collect data 24/7, rain or shine, thunderstorm or hurricane.

With user-friendly dashboards for desktop and mobile, you’re always informed about what’s going on at your site.

Add accounts for as many team members as you want, embed the data on your organization’s website, and set up public dashboards or mailing lists.

Set up customized alerts, so you don’t have to wonder if your lake levels are in compliance.

When water levels cross a threshold, Hyfi will let you know right away with alerts sent via email, text, or call. Set up your alerts exactly the way you like them with multiple layers of customization.

Our wireless, solar-powered water level sensor can be installed just about anywhere.

The sensor sits above the water and measures depth via ultrasonic pulse (sonar). It doesn’t touch the water, so you don’t need to worry about biofouling or tedious calibration.

Hyfi sensors are totally wireless: data is sent over the cellular network, and the battery is recharged via solar panel.

The sensor comes as one piece, purposefully designed to make installation and maintenance as easy as possible. The whole thing swaps out in two minutes with a screwdriver.

Proven reliability, even through hurricanes.

Hyfi sensors report what satellites miss and keep working though thunderstorms, hurricanes, and ice storms without loss of precision.

Built with a weather-proof, military-grade outer casing, the device is protected from the elements.

Live flood maps show you exactly what is impacted.

We connect real-time data from Hyfi monitors up to a bathtub model, creating live flood maps that show you exactly where the water is.

  • Use your flood map to set up customized alerts.

  • Explore different scenarios to create an emergency game plan.

  • Easily share the data with residents and regulators to get everyone on the same page.

Case study: Oceana County, Michigan

“Before implementing the sensor, we faced constant manual checks and unpredictable challenges with water level management.”
— Michelle Martin, Oceana County Drain Commissioner

Oceana County in western Michigan borders Lake Michigan and is home to over 70 inland lakes. The county is 61% water by area, which results in significant drainage and stormwater management needs. While Oceana County is home to only 26,659 year-round residents, the population triples in summer when “snow birds” and vacationers return to enjoy lakeside recreation and West Michigan’s natural beauty. Protecting these lakeside communities from flooding while simultaneously promoting ecological conservation is difficult given the vast area that must be monitored.

The Oceana County drain commissioner’s office is a small team charged with implementing flood control measures, controlling soil erosion, preserving water quality, and reviewing new construction plans to ensure adequate drainage. A core challenge the team faces is the need to monitor lake levels to ensure compliance with legally mandated limits. This is not easy given fluctuating inflows from rainfall, seasonal changes, and complicated upstream watershed dynamics. Failure to maintain compliance can lead to flooding, environmental damage, property disputes, fines, or lawsuits. Given the number of lakes in Oceana County, it just isn’t feasible to keep a close eye on all of these water levels around the clock — but that’s where Hyfi comes in.

Hyfi installed a real-time, wireless water level sensor and trail camera at Silver Lake Dam, a critical control point subject to unpredictable stormwater flows. Prior to deploying the sensor, drain commission employees had to drive out to the dam frequently to manually inspect water levels, a time-consuming and stressful process. With a Hyfi water level sensor and camera, they can check the current water level wherever they are, whenever they want. Real-time alerts offer early warning for high water levels, giving the team time to respond. To top it all off: now they’re building a continuous, historical record of the site’s hydrologic behavior, which they can use to evaluate long term trends and seasonal changes.
