Crews successfully plug partial break in dam & avert crisis, Harrisonville mayor says

HARRISONVILLE, Mo. -- The mayor of Harrisonville, Mo., now says he believes crews have managed to plug a partial break in the lower dam of  Lake Luna at Harrisonville City Park Tuesday. Police initially said this was at the lower dam of Harrionsville Lake.

Fox 4's Sean McDowell spoke with Mayor Brian Hasek who said he believes crews averted a crisis and have the situation under control. City workers have sandbagged the dam on the lake after water was seen running around the side of a spillway.

As of 1 p.m., water around the park appeared to be going down after being high across Lexington Avenue.

"It's gone down considerably, especially from the fact there's still water coming over the spillway," Mayor Hasek said. "It's just all these creeks and rivers. They just get overloaded. You do get brush that washes up, especially with all this flooding. It's just clogged everything up."

Harrisonville Police Department took to social media just before 11 a.m. to  warn residents that there was a "strong possibility" that the dam could break.

"We are urging everyone to avoid the area whether on foot or in a vehicle," police said in their post on Facebook.

Police evacuated homes in the area, and emergency services along with other departments from the city quickly arrived on the scene to begin efforts to fix the problem. Mayor Hasek says they had to evacuate four families, but police say there were actually 20 families evacuated.

According to the city of Harrisonville, officials were closely watching the dam while crews worked to fix the small area of erosion caused by the most recent flooding.

The city says between 7 and 8 inches of rain fell in Harrisonville.

Roads were closed in the area of the city park from Sycamore St. to Shady Lane on Lexington and from Ash St. to Shady Ln on Bradley, police said.

As of 11:50 a.m., many homes in the Cass County area were still under water. Fox 4 is monitoring the situation and has a crew in the area.

Mayor Hasek says city engineers plan to drain Lake Luna after this period of flooding ends. This is the third time this summer Harrisonville has been hit by high water.
