Grand River surge: Ottawa County braces for flooding

ROBINSON TWP. — Following a period of heavy rainfall, Ottawa County officials are issuing urgent warnings as the Grand River is projected to swell well beyond its banks this week.

Low-lying areas, particularly within Robinson Township, are expected to bear the brunt of the rising waters starting Monday afternoon, said Louis Hunt, director of emergency management at Ottawa County.

The National Weather Service anticipates the river will hit minor flood stage today, April 6, before escalating rapidly to a moderate flood stage by noon Tuesday.

Hydrologists expect the river to crest at 15.3 feet overnight Tuesday into Wednesday. Residents should prepare for a prolonged event, as water levels are not predicted to retreat below flood stage until Sunday, April 12.

Impact on infrastructure:

• Van Lopik Avenue: At the height of the crest, this thoroughfare in Robinson Township is expected to be submerged under one to two feet of water.
• Residential damage: Moderate flooding is anticipated for several homes in the immediate vicinity of the river.
• Emergency access: Significant flooding over local roadways will likely hinder response times for emergency vehicles.

Authorities are urging residents to exercise extreme caution near the water’s edge.

• Moving currents: Floodwaters in low-lying areas will be moving with a dangerous current; do not attempt to wade or drive through standing water.
• Road closures: Expect unpredictable road conditions throughout the week.

Local officials stress that 9-1-1 should be used strictly for life-threatening emergencies. Do not call emergency lines for general information or to report non-critical road flooding.

Residents are encouraged to monitor local weather updates and move valuable property to higher ground immediately.
