[84] UGFD officials argued that Nile perch must have spread to Lake Victoria by themselves by passing through the Owen Falls Dam when shut down for maintenance, but this is considered highly unlikely by many scientists. As a by-product of this the oxygen levels in the deeper layer of water are being depleted. The exception is Lake Kivu, which is part of the present-day Congo River basin, but is believed to have been connected to Lakes Edward and Victoria by rivers until the uplifting of parts of the East African Rift. the layer of water that lies below the thermocline, is noncirculating, and remains perpetually cold) were lower in 19901991 for a longer period than in 19601961, with values of less than 1mg per litre (< 0.4gr/cuft) occurring in water as shallow as 40 metres (130ft) compared with a shallowest occurrence of greater than 50 metres (160ft) in 1961. The sand filtration helps reduce water-borne diseases and is based on the use of the local environment. Hippopotamus, otters, reedbucks, mongoose and otter shrew, and many other species are native to this place. This may seem like a long time, but in geology, it is considered a fairly young lake. [44][51] Several of the remaining species are seriously threatened and additional extinctions are possible.
