Corps of Engineers to begin Pepin ice measurements
The U.S. Army Corps of Engineers, St. Paul District, will begin taking this year’s Lake Pepin ice measurements Wednesday Feb. 17.
The Corps takes ice measurements on Lake Pepin annually to forecast the navigational outlook on the Upper Mississippi River. Lake Pepin is the location of choice for these measurements because it’s the last part of the navigation channel where the ice breaks up due to slower river currents. A survey crew uses an airboat and a global positioning system to collect the data.
Measurements normally are completed weekly or biweekly until the navigation season begins. The data will be posted online at http://1.usa.gov/1R01qEG.
