Invasive mussels were reportedly found near Georgetown Lake in Montana, prompting concerns about their potential impact on the state's water systems. Boat inspection stations in the area have been busy, with some individuals attempting to bypass inspections, which can result in fines under a new law. The presence of invasive mussels, such as quagga mussels, could have catastrophic effects on fish and water systems, although it is unclear if any have actually been found in Montana's lakes or rivers.
