UPDATE March 15, 2019
As of 2 p.m. on March 15, 2019 urban flooding in the city of Cannon Falls had subsided, according to a city news release. There remained a few areas where water was still pooling as a result of frozen ground, but water was draining away in the majority of areas and was no longer a threat to property.
In the last 24 hours the Little Cannon River peaked and has receded about 18-20 inches and the Cannon River appear to have peaked after rising very rapidly. The current levels have inundated some green areas along the river, but have not impacted private property. The trail under the Highway 20 Bridge will be closed to use until the river recedes.
The river levels are being monitored continually and residents will be advised if conditions change.

The city of Cannon Falls was experiencing overland flooding Thursday, March 14, 2019, mostly along hillside areas.
The urban flooding was the result of frozen ground and the air temperature remaining above freezing for more than 24 hours combined with rainfall, according to a city news release. The greatest problem has been pooling water caused by either frozen culverts or areas without storm drain.
The storm drains in the city were functioning correctly, according to the releae.
The Little Cannon River and the Cannon River have risen approximately 39 inches over the past 12 hours. River levels have not impacted green areas or private property yet, but water has reached the trail under the Highway 20 Bridge. The trail will be closed until the river recedes.
Meanwhile portions of three state highways in southeastern Minnesota were closed Thursday because of flooding, while other highways in the region are reported with water on the roadway, according to the Minnesota Department of Transportation.
MnDOT cautions motorists to be alert for the potential of roadway flooding as rain continues in the region and the heavy snow pack melts. Other highways could be closed at times if water poses a safety hazard to motorists.
- Highway 16 south of Lanesboro
- Highway 60 at Highway 61 in Wabasha
- Highway 74 between Beaver and Weaver
Water is reported on the roadway at Interstate 90 east of Austin, Highway 74 south of I-90 and Highway 52 north of Cannon Falls.
For updated road condition information, call 511 or visit www.511mn.org.
MnDOT cautions motorists:
- Do not drive around barricades or into flooded areas.
- Six inches of water will reach the bottom of most passenger cars, causing loss of control and possible stalling. A foot of water will float many vehicles. Two feet of rushing water can carry away most vehicles including sport utility vehicles and pick-ups.
- When a road is closed it is illegal to travel in that area. Motorists can be fined up to $1,000 and/or 90 days in jail. If travelers need to be rescued from a closed road, other expenses and penalties will also apply.
