| One of the latest threats to the
Indus River is pollution. It has been said that there have been oil spills
and discharges from a few ships that anchor in the harbour of the city of
Karachi. It has also been said that there have been increases in salinity
levels caused by flow diversions in the Indus River.
Suspended Material and turbidity has also been an issue
especially following high released events in the Indus River. There have
been some material that has been washed from the catchment and into the
streams flowing into the storages. Some of the land uses such as
agriculture and land clearing can also lead to increased loads of
sediments and suspended materials such as silt, clay and other fine
particles which could be both organic and inorganic and would be entering
the storages. Because water storages are very effective at trapping and
holding sediments there have been loads of suspended sediments and
turbidity that can quickly change.
Pollution in the Indus River has
also caused a threat to the Indus River Dolphin, many of the Indus River
dolphin's have died from pollution in the Indus River. It started when
construction of numerous dams and barrages were build in the 1930's and
also split the population into small groups and degraded the habitat and
impeded migration. It's not just the construction of dams and barrages
that have put a threat to the Indus River Dolphin, there have been
accidental capture's in fishing nets and hunting for meat, oil and
traditional medicine which have had an impact to the river and has caused
a threat to the dolphin's.
