Belize rivers are at risk as well - look at Monkey River and over-extraction of water for banana farms (just one example)
Eco group warns of freshwater crisis

Some of the world's largest and best-known rivers are at risk of drying up
as a result of climate change, pollution and bad planning, a report warned
today.
The study by the environment group, WWF, focuses on the ten rivers most
danger of drying up or dying, and warns that, without action, the world
faces "a freshwater emergency".
Five of the 10 rivers listed are in Asia, including the Yangtze, the Ganges
and the Salween, highlighting the profound problems facing the region.
Europe's Danube, the African Nile and South America's Rio Grande are among
other rivers under serious threat.
Among the problems highlighted in the report - which is published ahead of
World Water Day on Thursday - are those caused by dams and dykes, such as
those along the Danube. WWF said these have already destroyed 80% of the
river basin's wetlands and floodplains.
The extraction of water for agriculture is also taking its toll on rivers
around the world, WWF said, with India's Indus river a notable example cited
by the study.
Over-extraction can lead to water scarcity and severely threaten freshwater
fish populations, which serve as an important food source for tens of
millions of people worldwide.
The report, which draws on eight international assessment reports, offers
solutions for the problems caused to rivers by over-extraction, pollution,
over-fishing, climate change, dams and invasive species.
It calls on governments to better protect rivers and ensure more sustainable
water use in order to protect people's livelihoods and the habitat provided
by freshwater sources.
"The world is facing a massive freshwater crisis, which has the potential to
be every bit as devastating as climate change," said Dr David Tickner, head
of WWF UK's Freshwater programme.
""We need business leaders and government to recognise that climate change
is not the only urgent environmental issue that needs to be dealt with, and
that they need to take notice of this freshwater emergency and act now, not
later."
Dr Tickner said businesses, particularly those relying on food and fibre
products that demanded a lot of water to produce, should look at how they
could be more water efficient.
"Conservation of rivers and wetlands and security of water flows must be
seen as part and parcel of national security, health and economic success,"
he said.
"Emphasis must be given to exploring ways of using water for crops and
products that do not use more water than necessary."
To ensure a worldwide response to the problem, WWF said there should be
agreements between countries as to how to manage water resources.
Dr Tickner added: "The freshwater crisis is bigger than the ten rivers
listed in this report but it mirrors the extent to which unabated
development is jeopardising nature's ability to meet our growing demands."
