ND increases aquatic nuisance species monitoringBISMARCK — North Dakota's Game and Fish Department documented only one new infestation of an aquatic nuisance species during the past boating season.
The agency says curly leaf pondweed was found in Lake Elsie in Richland County.
Officials say they spent a record amount of time monitoring the state's waterways. Aquatic Nuisance Species Coordinator Fred Ryckman says one of the biggest surprises was that zebra mussels were not found in the Otter Tail and Red rivers at Wahpeton. Young zebra mussels had been found in both 2010 and 2011.
But Ryckman says adult zebra mussels have become established and continue to move downstream in Minnesota's Otter Tail drainage. He says that emphasizes the need for North Dakota to remain vigilant.
