The second-driest occurred only a year ago, on the way to an odd sequence of an extremely dry fall and winter followed by the Twin Cities' second-wettest May on record and torrents of rain in northeast and southeast Minnesota in mid-June.

At the Southern Research and Outreach Center in Waseca, soil moisture is the lowest it's been since the drought of 1988. Minnesota state climatologist Greg Spoden called it a "flash drought." "We had 14 1/2 inches of rain in May. You'd have figured we had enough rain to last forever a that point," said Steve Eid, owner of Steve's Elk River Nursery, in the heart of the newly designated drought area. "But you're really seeing [drought] in the lawns and especially the shade trees right now. They're dropping leaves sooner than they should. I don't see where we're going to have a lot of good fall color because of the stress you see in the trees." Declining river flows and decreases in other water levels have prompted the Minnesota Department of Natural Resources to suspend or restrict surface-water use permits to businesses, golf courses, parks departments and others in various parts of the state. The agency told 16 users, from Moorhead-based American Crystal Sugar to a U.S. Fish and Wildlife Service project in southeast Minnesota, that their water withdrawals were being suspended until conditions improve. Some permits were suspended during last fall's dry weather; 350 were suspended in the epic drought years of 1988 and 1989, according to Greg Kruse, supervisor of the DNR's water- monitoring and surveys unit. American Crystal Sugar spokesman Jeff Schweitzer said the permits were for backup plans the company hasn't been using, so the suspensions will not affect operations. The relatively quick and late-season onset of drought conditions may have had some benefits. Unlike other farmers across the central United States, Minnesota farmers were able not just to dodge major crop losses but to actually score some wins. Sugar beet farmers might harvest a record crop and corn production may be up 7 percent. The beet crop got well-established early in the season, said American Crystal Sugar's Schweitzer; the beets, as a root crop, were able to draw moisture from the soil via a long taproot even as soils dried out. Meanwhile, low river levels are giving the U.S. Geological Survey (USGS) an opportunity to study how urban development along Interstate 94 affects the flow of the Mississippi River between the Twin Cities and St. Cloud. Rivers in the region are now flowing with only clear groundwater that has seeped into them, said Jim Stark, director of the USGS Minnesota Water Science Center. As a result, the agency can
