Blue Water Aquatics is committed to innovation, technical advancement, and continuous research to provide our customers with the best value and service. We can't think of anything more exciting in the field of vegetation management than the use of drone-based multispectral imaging to enhance our operations.


Drone-based multispectral sensing and imagery is transforming decision making in agriculture. Farmers have been using the technology for years to assess the health of their crops and now governments and universities across the globe are studying its application in aquatic vegetation management. Just as farmers want to see how healthy their crops are, lake managers want to see how unhealthy our target vegetation is after treatment. 

This drone-based sensor provides real-time data on targeted vegetation stress levels. This technology allows users to deliver cost effective, targeted treatments and spectacular data on our results. 


Multispectral sensors are instrumental in plant health and management. They collect visible wavelengths of light as well as near-infrared (NIR) and red edge wavelengths. These narrow spectral bands (40-60 nanometers each) show the structural index of a plant and spot subtle changes in reflectance. Hyperspectral sensors can also detect the type of crop or weed growing as objects leave unique fingerprints or “spectral signatures” in the electromagnetic spectrum. 

Multispectral sensors enable lake managers to identify stresses early on—when decisions can still be made to re-treat or wait and asses, thereby preventing a costly overuse of herbicides. Our moto is capture data, analyze data, act on data! Another advantage of aerial imagery is its ability to provide a bird’s eye view of your treatment area. A single image provides you with access to rich data about your target vegetation without having to fire up a single air boat or ATV.

Of course, you need to be able to interpret this information to make proper use of it and you must have access to the right data at the right time. We use professional grade agricultural analytics tools, reporting, and API integrations to interpret our images and turn them into useful, actionable data.

It’s clear that aerial and spatial imagery is providing a number of valuable insights that will impact our industry.

2. This is a multispectral photo of the same location. The areas of red are objects that have no chlorophyl, like sidewalks, sand, rocks and dead vegetation. The orange, yellow and green indicates various levels of vegetation stress. In the pond area you can see a thin ring of red around the bank. The west end of the pond is bright green, an indication that chlorophyl rich algae is forming.
