reservoirs are often very deep - it is difficult to estimate depth and they can be deeper than people expect
there may be hidden debris or underwater hazards which can cause injury, including weeds and plants which can entangle people under the water

there are no lifeguards on duty
the remoteness of some of these places can also hamper and delay rescue attempts
