EMINENCE, MO - Horses, not people, are fouling a southeast Missouri river popular among canoeists and campers.
The Jacks Fork River draws thousands of visitors each year. But a seven-mile stretch below Eminence, about 120 miles southwest of St. Louis, suffers from poor water quality.
A report released yesterday by the U.S. Geological Survey found that E-coli and fecal coliform levels worsened during trail rides that have attracted as many as 3,000 riders at a time.
DNA testing concluded that horses were a primary source of fecal coliform, followed by cattle and sewage. A USGS water quality specialist says boaters and swimmers are not to blame.
