Chilling foods to proper temperatures is one of the best ways to slow the growth of these bacteria. To ensure that your refrigerator is doing its job, itâs important to keep its temperature at 40 Â°F or below; the freezer should be at 0 Â°F.
At the surface, the water can warm up to 68oF. But Lake Tahoe averages around 50oF on the surface for most of the year. Further down, the water temperature remains constant at 39oF. At the surface, the water can warm up to 68oF. But Lake Tahoe averages around 50oF on the surface for most of the year.
At Ruapehu we monitor the lake temperature, water level and overflow along with the chemistry. The lake temperature varies from about 10 to 50Â°C; unfortunately this is not always a measure of activity as eruptions have occurred from both hot and cold lakes. The Mg (magnesium) values increase if new/fresh rock is in contact with the crater lake waters, while the Cl (chloride) changes with steam input.
