Huron Erie Connecting Waterways Forecasting System, HECWFS

NOTICE: This new HECWFS site displays our next-gen model output. Upgrades include a newer version of the hydrodynamic model (FVCOM 3.1.6 -> 4.3.1), river inflows derived from the National Water Model (NWM) and more realistic river temperatures derived from stream gages.

▸ Research to Operations Notice

These products are updated 2x per day around 6 and 18 UTC.
