North Sioux City, SD
According to state officials, the Big Sioux River has crested and water levels have started to fall this morning. Emergency management officials hope to have Interstate 29 near North Sioux City open for travel later today.
Back in the 1970s, exit 4 on Interstate 29 was designed as a diversion channel for flood waters. Crews spent Thursday installing a temporary levee to divert water from the Big Sioux River into nearby McCook Lake. Now crews will start to remove those protective measures. State officials have not given an exact timeline on when traffic will be restored to Interstate 29 between exits 4 and 26.
The National Weather Service says the Big Sioux River where Iowa, Nebraska and South Dakota meet already crested at a level lower than expected.
Reports show several portions of the Big Sioux River are receding north of McCook Lake. At North Cliff Avenue in Sioux Falls, the water is out of flood stage today. In two Iowa communities, waters are still at a major flooding stage. As of Friday morning, waters at Hawarden at slightly lower than 24.9 feet, the previous record. Further south, Akron is still in a similar situation with water levels near 23 feet.
