They say bad luck comes in threes, and that is the case on the Santee Cooper lakes this year. A trio of invasive weeds, including one still so new that the state hasn’t officially declared it such, has literally taken root and continues to hold on despite the best efforts of Santee Cooper’s analytical and biological sciences department. Invasive weeds are not new to Lake Moultrie or Lake Marion. But they are pervasive. This year is the 30th anniversary of hydrilla first being spotted in the system, in Lake Marion near Rimini. By 1994 it covered almost 45,000 acres of...

Once a clean lake in the 1980s, Squaw Lake in Oxford Township is slowly being taken over by Eurasian Milfoil.  Thick beds of Eurasian Milfoil now blanket most of the lake bottom. The lake is shrinking because the shore is thick with weed growth.  Squaw Lake was once used for water skiing and swimming, kids don’t swim there anymore. Eurasian Milfoil spread from boat propellers chopping fragments and raking it free and dumping fragments back into the water.  Eurasian Milfoil has the ability to root from fragmentation so new  colonies developed from just one small stem. Mechanical harvesting does not...

Just like the 1958 science fiction classic movie “The Blob”, Giant Salvinia burst onto the scene in the United States, becoming one of the world’s worst invasive aquatic plants.  In 1998 Giant Salvinia was recognized as a U.S. problem when eradication was resisted near Houston, Texas. Giant Salvinia has an “explosive” growth rate and can easily double in size in just a few days. Native to Southern Brazil, Giant Salvinia is now found in India, South East Asia, Africa, New Guinea, Australia, Indonesia, Philippines, New Zealand and a host of other countries including the United States. Biologists believe Giant Salvinia was...

One of the most common submersed lake weeds is Bushy Pondweed.  Bushy Pondweed is a rooted native weed that grows up from the pond bottom.  It has thread-like narrow leaves oppositely arranged on slender, sparsely branched stems.  Lake weed identification can be made by the microscopic teeth along the leafs edge.  Bushy Pondweed leaves are also slightly broader at the base than tip.  This water weed can be found growing in depths of 10 feet or more.
