| | A State Under Siege |
 | | From Washington to New Mexico, federal, state, and local fisheries officials are scrambling to prevent these biological pollutants—already rampant in much of the South, East, and Midwest—from reaching or further infesting western waters. |
 | | The biggest threats to Montana are the zebra mussel, now causing millions of dollars of damage each year in other states; the New Zealand mudsnail, which blankets riverbeds and threatens trout fisheries; and Eurasian watermilfoil, which covers shallow bays and lakes with thick vegetation mats, rendering them unfit for swimming and boating. |
 | | FWP, Montana State University, and other state organizations are also now assessing the presence of aquatic nuisance species in Montana, identifying potential pathways and high-risk waters, conducting surveys, and increasing research. |
