WAUPACA COUNTY, Wis. — The phrase big falls dam now carries an urgent meaning in Waupaca County: emergency management says water is going around the embankment, and people along the Wolf River are being told to leave without delay. That is the central fact behind a fast-moving public safety response that has widened from a weather alert into an evacuation.
What is the public being told about Big Falls Dam?
Verified fact: The Big Falls and Marion dams are at risk of failing, and the Weyauwega Area Fire Department is starting an evacuation because the Wolf River is rising. The National Weather Service issued a flash flood watch until 5 p. m., while officials in Green Bay also issued a flash flood warning for a break in the Big Falls Dam. In a separate emergency update, emergency management reported the imminent failure of the Big Falls Dam at 10: 16 a. m., triggering life-threatening flood concerns downstream.
Verified fact: Waupaca County Emergency Management says water is going around the embankment at Big Falls Dam. The dam did not break; it cannot hold back all of the water behind it. That distinction matters because the danger is not being framed as a distant possibility. It is being treated as active, with flooding already occurring along the Little Wolf River and residents in low-lying areas below the dam being told to move to higher ground.
Why are evacuations expanding along the Wolf River?
Verified fact: The evacuation in the threatened area is tied to the rising Wolf River, and the fire department is urging people to evacuate without delay. Residents are being told to bring wallets and purses, medications, phones and chargers, and pets. The community center at Weyauwega City Hall on Main St. is open for anyone without a safe place to go.
Verified fact: A shelter is being set up at Clintonville High School. In Clintonville, sandbags and sand are available in the Clintonville Library parking lot and at the Embarrass Volunteer Fire Department. The sheriff’s office is also encouraging residents to sign up for RAVE notifications on the Waupaca County website. The Wolf River is not expected to crest until Saturday, which means the current response is being organized before the river reaches its highest point.
Analysis: The timing suggests officials are trying to stay ahead of a worsening flood picture rather than react after roads and homes become inaccessible. The language used in the warnings leaves little room for delay: potential life-threatening flash flooding, immediate move to higher ground, and evacuation without delay. Together, those instructions show a system under stress, where the risk is not limited to one dam site but extends to the river corridor below it.
Who is in the downstream path if the dams fail?
Verified fact: If the Big Falls or Marion dams fail, Clintonville is in the path downstream. That makes the downstream threat concrete rather than theoretical. It also explains why local officials are already placing supplies, opening shelter space, and directing residents toward notification systems.
Analysis: The bigger story is not just that one structure is under pressure. It is that multiple layers of emergency response are now aligned around the possibility that the system may not absorb more water. The warning from emergency management that the dam cannot hold back all of the water behind it is the clearest signal that the problem is being treated as a public safety emergency, not a routine flood advisory.
What do the named agencies and local officials say the public should do now?
Verified fact: The National Weather Service has warned the public to turn around, don’t drown, when encountering flooded roads, noting that most flood deaths occur in vehicles. The Weyauwega Area Fire Department wants residents in the threatened area to evacuate immediately. Waupaca County officials are pushing notification signups, while Clintonville officials are making sand and shelter available.
Accountability note: The immediate burden now falls on residents to act quickly, but the responsibility also sits with the agencies managing this emergency to keep instructions clear, updated, and consistent as conditions change. For the public, the key question is no longer whether the big falls dam is under strain. It is whether everyone in the downstream area has heard the warning in time to move safely.
