I hate to mention this, But..
I was in Hawaii once just after a hurricane and just after they had harvested the sugar cane. The ocean was red for a mile out to sea where the clay and water from the cane field drained. The water from the run off cut a stream that was at least 4 feet deep on its way to the ocean.
The reason I did mention it is because the cane field looks to be up hill from the pond site.
