The chance of flash flooding southeast of Minot forced some families to evacuate their homes late last night.
The high runoff from the heavy snow and high temperatures is threatening a dike protecting homes along 54th Avenue Southeast - just south of the old KOA Campgrounds.
The problem is just north of these homes where a sink hole opened up in the 2011 flood.
Crews have tried to fill in the hole and shore up the dike, but Monday night, Arne Lynne was inspecting the dike and found it had collapsed into the sink hole.
County officials estimated the neighborhood - more than a dozen homes - would have only hours to evacuate before the water rushed in.
(Arne Lynne, 54th Avenue SE) "The water's right there. There's about this much dirt between the river which is about six feet higher than the water in that hole so once it starts to come through the main river channel, it'll be dumping into here"
The Lynnes put out word on Facebook that they needed help - and the neighborhood filled up with friends who helped several people evacuate last night.
While those families were evacuating construction crews were called in to try and save the neighborhood from the Mouse River Water.
The heavy equipment arrived at about 11pm Monday night and went to work quickly clearing trees from the area where an emergency levee would be built and from an area they needed to get dirt and clay from.
The area on the levee where the sink hole developed was more than 25 feet deep and only a small portion of the original levee was left holding back the mouse.
The crew from "Dig It Up" backhoe service worked into the night to get the new levee constructed.
Ward County Highway Engineer Dana Larson said that the area where the sink hole developed was part of a dead-loop that was cut off decades ago when these "temporary levees" were built that have since became permanent flood protection, although they are not certified by the Corps.
So what did it look like this morning after all that work?
Like this -- showing a successful effort at keeping the Mouse River at bay...but not without hours of work.
Crews were on site until four this morning working to build up this berm.
It proved to be strong and was able to do its job.
The Mouse is still running high -- and the sinkhole still gobbling up pre-existing levees -- but the new protection appears to be doing the job.
