In a recent development, flood warnings have been issued for the Missouri River as heavy rainfall over the past couple of weeks has resulted in a significant surge of water moving into the river. The areas most affected by the flooding include parts of northwest Iowa, where major to record-setting flooding has already occurred, leading to evacuations and significant damage.

The surge of water is expected to enter the Missouri River around Sioux City and gradually move downstream. High water levels are predicted to reach areas between Decatur and Blair by Monday, causing moderate flooding. The river is forecasted to crest at around 30 feet by Thursday, which falls well within the moderate flood stage.

Several impacts are anticipated due to the rising water levels. Wilson Island State Park is likely to experience flooding, along with potential impacts to industrial companies located along the river near Blair as the river approaches 30 feet. There is also a possibility that floodwaters may approach or even close portions of I-29 between Crescent and Loveland.

As the floodwaters progress, the Omaha area is expected to be affected by Tuesday morning. Waters are projected to rise to a crest over 34 feet by Friday, categorizing it as a moderate flood stage. Significant impacts are anticipated for riverfront properties, including NP Dodge Park, Freedom Park, Tom Hanafan Park, Fontenelle Forecast, and Haworth Park, all of which are expected to face some level of flooding. Additionally, there might be a potential impact on the I-29 & I-680 interchange, with the flooding of one of the ramps, as well as I-29 north toward Crescent. Floodwaters may also start to impact portions of Council Bluffs, particularly near I-29 around mile marker 59.

In the area around Plattsmouth, moderate flooding is forecasted to begin on Tuesday. A crest of 32 feet is expected by Friday, leading to significant flooding within the levee system. Areas not protected by levees can expect flooding, and floodwaters may reach the Plattsmouth Water Treatment Plant, with roads to the plant being flooded. Additionally, water levels may approach portions of Highway 34 and I-29 in the area.

Nebraska City is also predicted to experience moderate flooding along the Missouri River. Minor flooding is expected to begin Monday night or Tuesday, with a crest of approximately 24.5 feet forecasted by Friday. At this level, flooding is likely along North First Street, and widespread agricultural and lowland flooding can be expected. Although water may approach Highway 2, it is expected to be just below that level.

The Missouri River at Brownville is also at risk of moderate flooding. Minor flooding is projected to begin Monday night or Tuesday, with a forecasted crest of around 41.6 feet by Saturday. This level of flooding will result in significant agricultural and lowland flooding, with the power plant access starting to flood and minor impacts near Brownville.

It is important to note that there is still uncertainty regarding the exact amount of water that will enter the Missouri River from upstream flooding. Therefore, adjustments to the river forecast are possible, leading to significant changes in expected impacts. Those with interests along the Missouri River are advised to stay tuned to the latest forecast updates from the National Weather Service.

The duration of the impending flooding is expected to last for several days, possibly as long as a week, depending on any additional rainfall throughout the week. As of now, the forecast indicates dry conditions through Thursday, which means that there should not be a substantial addition of water to the river system.
