GRAND FORKS, N.D. - The Red River topped flood stage this morning in Grand Forks and East Grand Forks.
At 11 a.m., the National Weather Service reported the Red River was at 28.81 feet, just higher than the flood stage of 28 feet.
The 27-foot level is called the action stage, one in which city officials and workers begin to prepare for flooding.
"We've got a long check list of thing that we have to do, closing valves, closing gates, things that people won't even notice," said Kevin Dean, Grand Forks public information officer.
On March 5, the weather service forecast the probability of the Red River reaching major flood stage of 46 feet in Grand Forks-East Grand Forks at 73 percent.
Another flood forecast is expected to be released late this morning.
In the meantime, crews were getting planks ready to be placed in the floodwall along the East Grand Forks downtown boardwalk, this morning. The public parking lot behind Whitey's, Applebees and the Blue Moose restaurants was closed.
Grand Forks County crews are monitoring culverts today, looking for rising water at sites where farm fields might be draining faster than culverts are opening up, which can push water levels up to nearly road-high in the corners.
Over the past several days, county highway crews opened up long stretches of ditch, plowing out snow with backhoes so the draining could begin as fields turned from snow-white to dirt-black more and more, according to Gerald Sieg, county assistant superintendent of highways.
Benchmarks are established for certain actions, as the river reaches various levels. However, some of those benchmarks are more of guidelines than strict triggers, according to Dean.
On the Point Bridge, for example, the bridge is to be closed when the river hits 44.9 feet.
"If water is coming up really fast, we might close that bridge at 39 or 40 feet," he said. "If it's coming up really slow, we might close at 42 feet."
Last year, while both cities talked about the possibility of all three bridges connecting them, the Kennedy Bridge on Gateway Drive remained open.
"Hopefully, we won't have to close any bridges this year," Dean said. "Let's hope it's nothing more than an inconvenience."
Here are the action points, or critical observation points:
* 33 feet: Agricultural flooding between Oslo and Grand Forks.
