This winter brought a higher than normal snowfall, which means there's more to melt than usual.
"With the warm weather that we had, it really got rushing down this creek," said Bruce Mann, who lives near Owl Creek.
"We did have more runoff and with the ground being frozen, that always makes it a little harder because it doesn't have anywhere to go. It's a worry we have every year, but it's a little earlier this year than normal," said Sheridan city engineer Lane Thompson.
Mann says the area near his home was covered in water late last week.
"There was water running through the buildings. It was a lake," said Mann.
County officials have made sand bags available to the public. Mann and his neighbors put some up once the water levels died down.
"Right now, it's just a precaution," said Mann.
That's because more snow or rain is expected Monday night, which could lead to more flooding.
"We need to be prepared, because it's going to probably stay warm for a while. It can snow a lot, and melt right off the next day," said Mann.
Although city officials would rather see it snow.
"If it's snow, it should be fine. It'll slowly melt over the next day or two. If it rains really heavy and we don't get the snow, then we'll have to be a little more diligent, because we might see some localized flooding," said Thompson.
Sand bags are available at the Sheridan County Road and Bridge Shop at 48 Short Road.
