Weekend storm is mixed bag
BROWN COUNTY — Rainfall of six inches or more in the Marshall area Aug. 15-17 compared to about an inch around Lake Benton pleased some farmers and created Cottonwod River flooding in other places.
“We got adequate rain. We’re in the garden spot right now. We got a few tenths of an inch of rain at a time,” said Lake Benton corn and soybean farmer Bob Worth. “A few miles east of us, near Balaton and Marshall, they got lots more rain in those three days. We’re getting near September. We don’t have too many drying days left. A poorly tiled piece of ground will be wet for a long time. Crops are getting ready to shut down, so the rain is a double-edged sword for some people.”
Sleepy Eye farmer Mark Portner agreed the weekend rain was a mixed bag.
“Some places needed rain, others didn’t. It’ll help finish out the beans and corn for a lot of people, as long as there wasn’t too much,” he said. “There may be a lot of water in fields. You may not be able to see it from the road.”
National Weather Service (NWS) Meteorologist Joe Strus said six to eight inches of weekend rain was measured in Waseca County.
“One observer reported 5.5 inches near Sleepy Eye. Others reported two to four inches in and around New Ulm over the weekend. Some rain fell fast, an inch or two an hour,” said Strus. “Thunderstorms tracked slowly at times, dumping more rain.”
