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.
Protecting our shared natural resources that we all need to live – clean air, clean water, and healthy native habitats on land – is critical to creating and maintaining a robust economy and a good quality of life.
Have you ever set a glass of water on your bedside table only to take a drink out of it a few days later and think the water tastes “flat” or different? Chances are the water is missing dissolved oxygen. Dissolved oxygen (also called DO) is gaseous oxygen dissolved in water that you can’t see. Generally speaking, the more dissolved oxygen in the water the better it tastes.
The Cleveland Water system is designed with numerous layers of protection to help ensure only clean, safe drinking water reaches your tap. These advantages start with the location of where we draw water in from Lake Erie, extend to our four treatment plants, and continue throughout our delivery system.
Last week while monitoring sensors on Cleveland Water’s two buoys in Lake Erie, our staff noticed a downwelling event. Water temperature shifts like this can result in adjustments to the treatment process at our plants in order to maintain the quality and consistency of the water coming from your tap.
