## DEQ reviews Goose River discoloration
North Dakota Department of Environmental Quality reviewed water samples and field measurements after red discoloration was reported near Caledonia.
## DEQ works with USGS on river testing
DEQ collaborated with U.S. Geological Survey to gather river conditions data and collect samples for North Dakota State Laboratory testing.
## Discoloration causes include low water flow
Low water flow, high temperatures, groundwater entry and organic matter buildup depleted river oxygen, causing red discoloration.
## Wastewater facility not identified as cause
DEQ results showed no indication that a permitted wastewater facility between Mayville and the Red River caused the discoloration.
## Public advised to avoid river recreation
The public should avoid drinking from or recreating in the affected river portion until precipitation improves conditions.
## DEQ continues river monitoring
DEQ will monitor the river and downstream Red River of the North segments to track improvements after precipitation.
## Key takeaway

North Dakota DEQ says red discoloration in Goose River caused by low water flow and oxygen depletion, not wastewater facility.
