Lake Erie

The reported Lake Erie water temperature is taken at the Buffalo Water Treatment Plant located on Lake Erie at the entrance to the Niagara River.  The reading is taken at a depth of 30 feet. This data is unofficial.

Lake Ontario

The reported Lake Ontario water temperature is taken at the Monroe County Water Treatment Plant near Greece, N.Y. The temperatures is measured at the intake pipes about 1500 feet offshore at a approximate depth of 35 feet. The Lake Ontario temperature occasionally may not be representative of the surface temperature due to upwelling. This process, more common during the summer months, brings colder water from the deeper parts of the lake toward the surface near the temperature sensor. The surface water may be significantly warmer. This data is unofficial.
