Missouri River to flood parts of the Katy Trail this weekend
COLUMBIA - The Missouri River is expected to reach moderate flood stage in Jefferson City, Glasgow and Hermann this weekend. The rise in river levels is due above average rainfall over the Missouri River Basin over the last several days and this will result in flooding for parts of the Katy Trail.
Friday Midday Update: The Missouri River is on this rise across much of the region. Currently most of our river gauges are in Minor Flood Stage. Glasgow is in Moderate Flood Stage pic.twitter.com/PpnzVDCzIa— Matt Beckwith (@KOMUMatt) May 29, 2020
RIVER GAUGE AT JEFFERSON CITY
Waters are expected to rise Friday through Saturday and river levels are expected to reach moderate flood stage Friday night into Saturday. Moderate flood stage for Jefferson City is defined as 25’ and the river is expected to crest Sunday May 31st at 28.7’. This could result in the Katy Trail flooding in several locations such as Wilton, Easley and Rocheport. The levee that protects McBaine could also be breached.

This forecasted crest of 28.7’ is well below the crest of 33.44’ that the river gauge in Jefferson City measured in June 2019.
