It's a lake. It can be a really big lake.
However
by American Standards, it's not much. Lake Erie, the smallest of the
American Great Lakes, is 25,700 square kilometers. the Tonlé Sap lake,
in the dry season, has a surface area barely one-tenth that large and
it's only a meter deep. More of a pond than a lake. That NASA satellite
image on the right suggests this is not a destination location for
vacationers.
But Tonlé Sap is no ordinary lake/river
system. Depending on the source, the very name means Great Lake or Large
Fresh Water River. And when the monsoons come, things happen.
During
the rainy season, the nearby Mekong River is at full flood, and the
Tonlé Sap river that drains the lake reverses its direction, raising the
level of the lake to
nine meters. The lake's volume increases 50-fold. Its surface area
becomes six times larger or more -- 16,000 sq km (the State Department
says 24,605 sq. km.) As it swells, the Tonlé Sap lake becomes the
largest
freshwater lake in Southeast Asia. When the river reverses direction, it
brings with it abundant alluvial nutrients, which makes Tonlé Sap the
strategic protein resource
for the people of Cambodia.
The Tonlé Sap system is an ecological hot spot
designated as a UNESCO biosphere in 1997. Among its riches are 149 species of fish, nearly extinct Siamese Crocodiles and
the world's largest population of freshwater snakes. Also present, in diminishing numbers, is
the Mekong giant catfish, the largest freshwater fish in the world. It
can reach 10 feet in length, and weigh more than 500 pounds. And for
this river system, it is the canary in the coal mine. According to
Wikipedia, it is "especially vulnerable to chemical changes, which is
beneficial in alerting authorities of trouble in the river ecosystem."
The resource is threatened by overfishing and ecological degradation,
and that can spell problems for Cambodians who depend on Tonlé Sap for
their livelihood and for food.
In March, I
am visiting the Tonlé Sap River with my childhood friend, Jay Hastings. I
have joined his effort to help protect that resource in a very small
way.
That's what this blog is about. If you want to
follow it, you don't have to do anything. I think I'll be able to let
you know every time there's a new posting. There's probably going to be
plenty of Internet linkups in Phnom Penh.
If you don't
want to follow it, just let me know, that's perfectly understandable.
Your life is busy and you get more e-mails than you want.
But
if you're curious to see how the other half lives, come along with us
as we prepare for the trip and then take that 20-hour flight to a part
of the world most of us have never seen.
I'll be
telling a small part of the story of a people who are still recovering
from one of the worst genocides in a century -- how they live, and what
some of them are doing to make their lives better.
It's going to be hot -- about 100 degrees Fahrenheit, but you won't be the ones sweating. Thank your lucky stars for that.
If
someone has forwarded this to you and you would like to be added to the
mailing list, let me know by e-mailing me at dancingpotter@gmail.com.
Love,
