http://www.rivergages.com and http://www.mvp-wc.usace.army.mil are both sites run by the Corps of Engineers that give up-to-the-hour information on river levels and flow, as well as river temperatures.

Try the National Weather Service site.

Try this one. http://www.waterdata.usgs.gov/mn/nwis/current?type=flow. this is upto the date for most rivers and lakes in MN.
