The U.S. Army Corps of Engineers, Omaha District completed an initial breach closure on levee L550 south of Watson, Missouri, Thursday. This closure of breach L-550-B-I near river mile 538 stops the inflows of water, thereby allowing for the start of follow-on construction activities aimed at increasing the level of flood risk management to approximately the 4% Annual Chance Exceedance (25-yr) level for this section of the L-550 Levee System until the system can be fully rehabilitated.
