Our Platform

Harmful Algal Bloom and Water Quality Forecasts

Check out our harmful algal bloom dashboard for Detroit Lake in Oregon

ClearWater is the platform that synthesizes, cleans and formats all relevant data; custom machine learning algorithms then create accurate forecasts and clear visualizations provide easily interpretable and actionable results.

Small, Big, Dirty or Clean: All Data

We scrape, parse and format all data that is relevant to harmful algal blooms. These data can be downloaded by our users for a variety of applications (e.g., GIS). In addition, we create online interactive visualizations for these data, so that users can explore patterns and trends. These data include:

  • weather station,

  • stream gauge,

  • water-sample data and 

  • satellite imagery

Our customer HAB prediction algorithms leverage all these available data to make the as accurate as possible forecasts. 

Accurate and Resilient Forecasts

The data we collect are used primarily to train custom machine learning algorithms that estimate the future concentration of specific species of (harmful) algae and the toxins they produce. The forecasts target multiple operationally relevant time-horizons, e.g., 10 day look-ahead, as well as long-term seasonal forecasts. ClearWater Analytica was the first to provide HAB forecasts, with an accuracy of >85% depending on the location. Our forecasts are also resilient to data drop-outs, being able to provide accurate predictions even with missing data.

HAB Driver Identification

Weather and climate risks are an immediate threat to the provision of clean and drinkable water. Be on the forefront of protecting your key source waters from the impacts of extreme weather events and climate change through insights about your major climate risks, and how risk mitigation strategies can be optimized. ClearWater will quickly provide:

  • An in-depth evaluation of your source water's risks based on our machine learning models

  • Leverage the wealth of peer-reviewed scientific literature and expert opinion

  • Deliver customized risk assessment and mitigation strategies
