NWS monitoring river levels, not anticipating 2011 repeat

By  | 

BISMARCK, N.D. - The National Weather Service in Bismarck is monitoring the Missouri River around the clock. Hydrologist Alan Schlag says water levels are on a steady rise and should reach 13 feet by the weekend.

That will cause enhanced erosion as water rises above rip rap, and Schlag says intrusion of ground water into basements could also occur. He is not anticipating a repeat of the flood of 2011, which closed roads and cut off access to homes.

"We're still in the single digit percent for risk. It's not a 20-percent risk, it's not a 50-percent risk of us getting to problematic water levels, it's something well below 10-percent, probably in the two to three percent, which is still not zero, but it's not something I would lose a lot of sleep over," said Schlag.

Schlag says flood stage on the Missouri was lowered from 16-feet to 14-feet after 2011 to account for impacts that occurred seven years ago.
