Summary: Repairs would include placing a rock dike along the embankment to stabilize the breach and placing sand fill in the breach. If left unrepaired, continued growth of the breach has the potential to cut off the Platte River and cause a shift of the confluence with the Missouri River. This shift would cause unstable navigation channel depths, considerable Bank Stabilization and Navigation Project (BSNP) expense to stabilize the new confluence, sediment deposition with unknown impacts to river flood levels, and risk to adjacent infrastructure including the City of Plattsmouth water treatment facilities.
Geographic Scope: Platte River Mile 1.25, upstream of Missouri River confluence near Plattsmouth, Nebraska
