Each year Cleveland Water issues a Water Quality Report for our customers. This annual report, also called a Consumer Confidence Report, provides a review of our water quality during the past year, including testing results and information.
Several days ago we told you that Lake Erie’s bottom water temperatures had reached below the magic number of 39.2°F, meaning the surface could freeze as long as the air temperature above the lake stayed below freezing.
Since the start of 2019, the temperature of the lake water coming into Cleveland Water’s Garrett Morgan Treatment Plant has stayed below 39.2°F (4°C). This is the magic number that signals the lake’s surface can now start to freeze.
43.6 degrees Fahrenheit is the official temperature for Lake Erie offshore of Cleveland as of today, November 28. While that's still a good bit above freezing, as winter progresses and the lake temperature continues to drop we're on the lookout for ice formation.
