LAKE OF THE OZARKS — Results from the July water testing for E. coli bacteria were released last week at the Lake of the Ozarks Watershed Alliance meeting at Lodge of Four Seasons...
...James Vandyke, a MDNR geologist from Rolla, told about 40 people at last week’s LOWA meeting about the Ozarks’s unique Karst topography and how inter-connected groundwater systems are.
According to Wikipedia, Karst topography is a three-dimensional landscape shaped by the dissolution of a soluble layer or layers of bedrock, usually carbonate rock such as limestone or dolomite. These landscapes display distinctive surface features and underground drainages, and in some examples there may be little or no surface drainage. Some areas of karst topography, such as southern Missouri and northern Arkansas in the USA, are underlain by thousands of caves.
Caroline Toole, LOWA’s recording secretary, is also a chemistry and physics teacher at School of the Osage and a Stream Team leader on the Little Niangua River in western Camden County. She said Vandyke’s presentation on Karst topography underscored the susceptibility of the lake’s watershed to ground water pollution.
“For example, Laclede County has a sink hole dump and the state did some trace sampling and determined that the water [from the sink hole] comes out at Ha Ha Tonka spring,” she said. “That creates special challenges to LOWA’s mission, because what ends up in our watershed isn’t always easily traced.”
