NOAA - Great Lakes Environmental Research Laboratory
NOAA issues three Lake Erie HAB products each year. A Lake Erie HAB Seasonal Retrospective is issued in November at the end of the bloom season as the final bulletin of the year.
Western Lake Erie Harmful Algal Bloom Early Season Projection
The Western Lake Erie Harmful Algal Bloom Early Season Projections, issued beginning in May,
estimate bloom severity based on measurements of phosphorus loading from the Maumee River combined
with long-range forecasts and historical records. Projections are issued until NOAA issues he Seasonal
Lake Erie HAB Forecast in early July.
Users can subscribe to
receive the projections via email and they are also posted
online.
Seasonal Lake Erie HAB Forecast
NOAA issues a seasonal forecast in early July. The Seasonal Lake Erie HAB Forecast gives coastal managers and drinking
water facility operators a general sense of how "bad" the upcoming bloom season has the potential to be. The seasonal
forecast is an ensemble of models based largely upon phosphorus discharge from the Maumee River.
Lake Erie HAB Forecast
During the bloom season (typically from June until October),
the operational NOAA Lake
Erie HAB Forecast provides the current extent and 5-day outlooks of where the bloom will travel and what concentrations
are likely to be seen, allowing managers to determine whether to take preventative actions. A forecast analysis is updated twice
weekly and emailed to subscribers.
