CAVALIER, N.D. — National Guard units from Minnesota and North Dakota placed two large pumps at the Bourbanis Dam on Friday, May 6, to minimize water flow at the damaged structure.
On Tuesday, May 3, the North Dakota National Guard was called to stabilize the dam, which was in danger of rupturing , with one-ton sandbags.
The Minnesota National Guard placed the pumps, which both weigh more than five tons and are leased from a private contractor, using a CH-47 Chinook helicopter. The Minnesota National Guard action is in response to an Emergency Management Assistance Compact request from the state of North Dakota for a helicopter capable of placing the pumps, which each weigh more than five tons.
“Spring floods continue to put our fellow Americans at risk, and when disaster hits, Minnesotans have always stepped up. We have the resources needed to continue addressing flooding here in Minnesota, while also being in a strong position to help our neighbors,” Minnesota Gov. Tim Walz said in a press release. “I am proud that the Minnesota National Guard has answered this call to serve.”
North Dakota is facing significant overland and riverine flooding within the Sheyenne River and Red River basins caused by the rapid melt of the record-breaking snowfall and the heavy spring rains. The resources of affected local, county, and state governments "are inadequate to meet the demands caused by the flooding," Walz’s office said in a news release. North Dakota Gov. Doug Burgum has declared a statewide emergency.

EMAC is a mutual aid agreement between all 50 states. A requesting state asks for resources based on their needs and while any state can respond, there is no obligation to participate, according to the news release. The Minnesota Department of Public Safety Homeland Security and Emergency Management division coordinates the state’s EMAC requests.

Army Col. Gregory Fix, Minnesota National Guard’s State Army Aviation Officer, said the CH-47 Chinook “is a tremendous asset for the National Guard,” and “has the capability to lift heavy loads greater than 10,000 pounds, and moving the two pumps for flood support is just one example.”
The Guard members and aircraft were from the St. Cloud-based B Company, 1-171 Aviation Regiment.
“This aviation unit has many hours of experience moving equipment,” said Fix. “They recently returned from a deployment to Iraq and Kuwait. While deployed, the unit provided the aerial movement of troops and supplies throughout the area.”
This isn’t the first time the Minnesota National Guard has assisted with flood operations in North Dakota. Fix said the Minnesota National Guard has worked with their neighbors to the west multiple times during floods. Additionally, in 2019 aviators delivered hay to cattle in Nebraska due to extreme flooding in the area.

On Friday afternoon, LuAnn Kemp, secretary for the Pembina County Water Resource District said she could not provide any information about where water will be redirected by the pumps or how the redirection of water from the Bourbanis Dam will affect surrounding areas. Pembina County Emergency Manager Samantha Diemert also declined to answer questions about the dam and placement of pumps.
On Tuesday and Wednesday morning, the North Dakota National Guard placed 213 total sandbags at the dam, according to Bill Prokopyk, spokesman for the North Dakota National Guard. The sandbags were filled locally by volunteers in Cavalier, and placed using two UH-60 Black Hawk helicopters from Bismarck.
The Bourbanis Dam is one of 10 dams in the Tongue River Watershed. According to Pembina County Emergency Management updates, other dams in the watershed are operating as designed, and water levels in the watershed are being monitored. The Tongue River is a tributary of the Pembina River, which then flows into the Red River.
