Participate in the EFI-USGS River Chlorophyll Forecasting Challenge!
Submit to the river chlorophyll forecasting challenge, co-hosted by the USGS Water Mission Area and Ecological Forecasting Initiative.
We invite you to submit to the EFI-USGS River Chlorophyll Forecasting Challenge! Co-hosted by the Ecological Forecasting Initiative (EFI) and U.S. Geological Survey (USGS) Proxies Project, this challenge provides a unique opportunity to forecast data from the USGS. By participating, you’ll sharpen your forecasting skills and contribute to vital research aimed at addressing pressing environmental concerns, such as harmful algal blooms (HABs) and water quality.
Why river chlorophyll?
Algal blooms cost the U.S. economy $2.2-4.6 billion dollars per year on average in water treatment and economic losses (Hudnell, 2010). Developing the capacity to predict when and where these blooms might occur could greatly reduce their impact. While much attention has been given to advancing predictive capabilities for algal blooms in lakes, river algal blooms can also cause substantial socio-ecological impacts, yet our understanding of their dynamics lags that of lakes. Fortunately, the number and diversity of observations that can be used to predict algal blooms are rapidly increasing (e.g., chlorophyll sensors), which enables powerful modeling techniques to extract patterns from these data and predict future HABs with sufficient lead time to initiate appropriate management interventions. Chlorophyll serves as a reliable proxy for algal biomass and can indicate when there might be an impending algal bloom. With this challenge, we hope to compare many different approaches for forecasting river chlorophyll to better understand the predictability of chlorophyll and potentially HABs in rivers across the United States.

How can I get involved?
Getting involved is easy! Simply visit our EFI-USGS River Chlorophyll Forecast Challenge website to register and gain access to all the necessary resources and instructions. Whether you’re a seasoned researcher, a budding data scientist, or participating in a classroom project, there’s a place for you in this challenge. We provide step-by-step instructions, target data, numerical weather forecasts, and tutorials to empower you throughout the process. Plus, all forecasts and scores are publicly available, fostering transparency and collaboration within the community.
Who is organizing?
The Ecological Forecasting Initiative (EFI) is a grassroots consortium dedicated to building and supporting an interdisciplinary community of practice around near-term ecological forecasts. EFI has been running a separate forecast challenge since 2021, welcoming participants to forecast ecological data at National Ecological Observatory Network sites (Thomas et al. 2023). Building forecast models, generating forecasts, and updating these forecasts with new information requires a lot of data, and fortunately the USGS is largest provider of in-situ water information in the world. The USGS Proxies Project teamed up with EFI to select monitoring sites that fulfill the data requirements for a forecast challenge while also being strategically chosen based on their scientific, management, or social significance. Our EFI-USGS team is committed to advancing research in ecological forecasting and environmental modeling and your participation enhances this effort!

Are there any prizes or awards?
While there are no monetary rewards, the benefits of contributing are substantial. Participants can expect to advance their forecasting skills, find joy in tackling complex ecological problems, and potentially be involved in the creation of manuscripts based on their contributions. Our forecasting challenge serves as a platform for the ecological and data science communities to enhance their skills in forecasting ecological systems. By generating forecasts, participants contribute to a synthetic understanding of patterns of environmental predictability.
