Highway 30 open: The Iowa Department of Transportation is delaying installation of a flood barrier wall along portions of the north side of U.S. 30 from the Missouri River crossing near Blair, Neb., to Interstate 29 near Missouri Valley, Iowa.
The work and closure of U.S. 30 had been scheduled to begin at 8:30 a.m. Tuesday. The road will be open to travel.
Floodwater continues to fill the basin north and south of U.S. 30, but it appears to be leveling off after a private levee in Harrison County was breached by members of the levee district Friday, state officials said Monday.
The site remains on the Iowa's list of roadways at high risk of closure because of flooding.
No sightseeing: The Army Corps of Engineers warned people again to stay off levees along the flooded Missouri River.
Col. Robert Ruch, commander of the Omaha District, said he saw a family with young children strolling along a threatened levee Monday.
Ruch reminded that the flood-soaked levees are dangerous places and are off-limits to the public.
Pumping sand: Private sump pumps may be damaging levees in Council Bluffs.
In certain situations, sump pumps are contributing to the creation of sink holes and other levee weak spots when the pumps draw sand or other soil material, according to city officials.
Sump pumps expelling sand are obvious to spot because there is sand in the ejected wash of water.
Bluffs officials have the authority to deem sand-spewing sump pumps a nuisance and may order property owners to shut them down if they are determined to be contributing to possible damage of the levee system.
Fort Randall Dam: Releases from Fort Randall Dam in South Dakota will be reduced Thursday for Army Corps of Engineers officials to inspect repair work that had been done on the structure before the spring runoff season.
Col. Robert Ruch, commander of the corps' Omaha District, said Monday that engineers want to see how the structure is performing. The dam is releasing water at a rate of about 155,000 cubic feet per second.
A similar inspection was conducted last week at Big Bend Dam in South Dakota, upstream from Fort Randall.
He said Gavins Point Dam, immediately downstream on the Nebraska border from Fort Randall, continues to perform well and no similar closure is expected.
New location: The briefing for applicants seeking disaster assistance under Iowa’s presidential declaration will be held at 2 p.m. Wednesday at Iowa Western Community College’s art center.
Officials will be in Harrison County this week to conduct individual assistance damage assessments, according to Larry Oliver, county emergency coordinator.
Flooded land: About 170,000 acres of Nebraska land is inundated by Missouri and Platte Rivers floodwater, according to the National Geospatial-Intelligence Agency. That's the equivalent of more than 265 square miles.
Sewage help: Lincoln has been helping sewage disposal services in Omaha and Plattsmouth dispose of their waste.
Steve Masters in Lincoln Public Works said that a few trucks pumping waste from septic tanks on farms, industrial sites and other areas have dumped the sewage into one of Lincoln's wastewater treatment plants.
Those trucks usually dump the waste at plants in Omaha and Plattsmouth, but those plants are overwhelmed by Missouri River flooding. Raw sewage is being dumped into the river in those communities.
