Grand Rapids, MN (Northland's NewsCenter) -- The storm on Monday, July 2, leaves 11,000 Lake Country Power members still without power.
Straight-line winds that reached 80-miles-per-hour will have Lake Country Power crews working through the July 4 holiday to restore service.
The co-op has also called in line crews from subsidiaries and other cooperatives to restore power still impacted by the relentless July 2 event.
Downed trees caused extensive damage to the co-op's electric system and leveled a one-mile stretch of line along Highway 46 north of Deer River.
The destruction is primarily centered near Grand Rapids, within a 150-mile radius of the city.
The straight-line winds caused transmission line, substation and distribution line outages and downed trees have blocked access along county roads and state highways, which has slowed restoration efforts.
With the magnitude of Monday's wind storm and the amount of destruction left in its wake, restoration of electric service is expected to take several days to repair.
Three of Lake Country Power substations lost power and power line crews have been working around the clock to restore power to members.
One of Minnesota Power's transmission lines that feeds into Lake Country Power's service area near Nashwauk and Crooked Lake is also out of service.
Large poles are down in some areas.
Additional outages have been reported in the Mountain Iron and Kettle River service areas as well.
Lake Country Power line crews worked through the night and will remain working to restore service as quickly and safely as possible until all services are restored.
