A long-running legal battle over stopping invasive aquatic weeds from spreading through Tahoe Keys, a man-made lagoon and wetlands system that feeds into Lake Tahoe, hit a turning point [last] week after a Superior Court judge halted a controversial weed-control project. [Weeds] have plagued the Tahoe Keys lagoons for decades following the subdivision’s construction in the 1960s on top of what was once a large wetlands environment at the southern end of Lake Tahoe. The plants have since grown out of control and significantly impacted the 163 acres of waterways that make up the lagoon system.
