It takes more heat to raise the temperature of a given volume of water a certain number of degrees than it does to raise the same volume of any other liquid the same number of degrees.

all lakes have a thermocline. Summer time the thermocline will be higher. In winter lower. Thermocline is a layer of water that is separated by temperature. Some lakes have a summer thermocline of 40 feet. But colder water in any lake will fluctuate with how cold and access to sunlight.

That depends on the time of the year, in the winter nearly all freshwater lakes are frozen, most rivers with the exception of the fast moving ones (the rivers never completely freeze). Even the bering sea has Sea Ice. But, in the summer many lakes in Alaska can get up in to the 70s.

Lakes are normally cold.
Tap water temperature as "cold" is its normal temperature, depending on what your water source is. Underground water usually from wells/reservoirs is about 55 degrees, where as some parts of the country water comes from above ground lakes/reservoirs, and there the temperature will vary. Its warmer in the summer and can get really really cold in the winter as the above ground water temperature drops.
Evaporation cools it.
