Yes, especially standing water can carry many bacteria.
why is salt in a lake in the hot,dry region
Yes, Lake Michigan has fresh water. Oceans contain salt water.
No not unless it is purified. No lake water is drinkable due to pollution, bacteria in the water, and other conditions.
Lead and many other types of bacteria that can come from your lake or ocean water
A pool the water is sanitized and with proper water chemistry. A lake may contain harmful bacteria. Water chemistry in a pool is balanced to somewhat obtain the chemical levels that are present in tap water that you drink. You are trying to duplicate that with pool chemistry. You drink chlorine and wash clothes in it. After hurricanes and such small amounts of bleach is used to sanitize water enough to drink. Think about it. Would you drink that lake water or drink your properly balanced pool water instead? Hope this is helpful.
There is a channel....a opening where the salt water can enter An inland lake can also be salty if mineral deposits under the lake contain salt, or the lake has only inflowing water and no out-flowing water. Overtime the inflow will bring minerals into the lake, without a way for the water to exit the lake, the waters of the lake will evaporate naturally, leaving the deposited minerals, increasing the water's salinity.
The lake turned to ice
Bacteria and small parasites. You could get very sick depending on which lake. Talk to your local Game and Wildlife people.
The Sea of Galilee is fresh water, fed by the River Jordan. The salinity is beginning to increase from salt water springs in the bed of the lake because too much fresh water is being extracted, but it remains a fresh water lake at present.
