Detailed explanation-1: -Warmer water temperatures in deep lakes slows down processes that add oxygen to the water, creating dead zones, or areas with less oxygen that are unable to support life. These dead zones can produce large-scale fish mortality and toxic algal blooms.
Detailed explanation-2: -In general, lakes tend to be larger and/or deeper than ponds, but numerous examples exist of “ponds” that are larger and deeper than “lakes.” For example, Echo “Lake” in Conway is 14 acres in surface area with a maximum depth of 11 feet, while Island “Pond” in Derry is nearly 500 acres and 80 feet deep.
Detailed explanation-3: -Temperature varies in ponds and lakes seasonally. During the summer, the temperature can range from 4° C near the bottom to 22° C at the top. During the winter, the temperature at the bottom can be 4° C while the top is 0° C (ice).
