Public health advisory issued for Devils Lake. |
September 18, 2007 |
The Cyanobacteria Bloom in Devils Lake has subsided, and it has been two weeks since visible scum has been washing ashore at any of the 6 monitoring sites. The public should use its best judgment when using Devils Lake or any surface water for recreation as cyanobacteria can repopulate quickly, but with cooler temperatures, clearer water and low densities lake wide, that has become increasing less likely. Based on these observations and facts lifting of the CAUTION posted by the Devils Lake Water Improvement District is warranted |
