The process in which oxygen is removed from the water by the decomposition of large amounts of organic matter
The lake will have heaps of plants and algae. they will then start dying and the "bodies" will rot which is a process that consumes oxygen, if too much organic mass rots it consumes all the oxygen in the water and everything in the lake dies- this process is called eutrification
In general, when water is polluted it is called, surprisingly enough, water pollution. Specifically, livestock waste and agricultural chemicals would be chemical water pollution (since there are chemicals dissolved in the water), to differentiate these from particulate pollution (soot, silt, and clay suspended in the water).Excess Nitrates from organic or inorganic fertilisers can also cause severe algal blooms. this process is called Eutrification.
