Algae advisory issued for Lake Tschida
An advisory has been issued at Lake Tschida after the N.D. Department of Environmental Quality (NDDEQ) found an elevated level of toxins associated with cyanobacteria, or bluegreen algae.
The NDDEQ has issued advisories for 11 bodies of water, including Froelich Dam in Sioux County and Sweetbriar Lake in Morton County. The only warning issued in the state is for Patterson Lake in Stark County.
After receiving a report of a harmful algal bloom (HAB) on Lake Tschida, NDDEQ staff visited the lake and analyzed the water using test strips. The test strips indicated an elevated level of toxins associated with an HAB. So, a water sample was collected and sent to an independent laboratory for confirmation, according to Grant County Emergency Services.
