Fish reproduce too quickly
( Fish reproduce too quickly )
During eutrophication, excessive nutrient inputs lead to massive algal blooms. As these algae die and decompose, oxygen levels in the lake decrease due to increased microbial activity, which consumes the oxygen. This can result in oxygen depletion, leading to conditions harmful to aquatic life.
Euthrophication occurs when the level of nutrients in a body of water - usually a lake - beocmes abnormally high. A common cause is that the lake is fed by a stream carrying run-off from agricultural land. The fertilisers in the run-off may cause excessive vegetation growth.
if the lake had once been connected to the ocean it is possible.

NO. Lake Nasser was a result of the creation of the Aswan High Dam.
Please rephrase - the question is unclear. No lake is that big or a possible answer to the question is none or that no such lake exists.
