People can check water conditions and report any suspected harmful algal blooms at DEQ.North Dakota.gov. He added everyone plays a role in keeping algal blooms at bay because everyone plays a part in feeding them. Last year, there were a total of 26 alerts issued for harmful algal blooms during peak season, which lasts through September.
