Aquifer

Explanation:

Aquifer's are underground water sources. So this answers a couple of questions. Generally, aquifer's are pretty small. And because it is an underground water source, it never see's light, like the question suggests. The temperature is constant because it never see's the sun and remains in the same place, therefore there is nothing that has the ability to change the temperature of the environment.
