SHERIDAN — After two inches of rain that fell over the weekend caused several rivers and streams to crest, local waterways are beginning to recede according to estimates from the National Oceanic and Atmospheric Administration.
Goose Creek running through Sheridan reached a max height of 9.49 feet, almost 2 feet above flood stage, at approximately 7:46 p.m. on Monday, moving water at approximately 4,830 cubic feet per second. Since then, observed flooding has steadily decreased past flood stage and currently sits at 6.5 feet.
South of Sheridan, the Little Goose Creek at Big Horn decreased from moderate to minor flood stage late last night and currently flows at an estimated 4.3 feet. Forecasts project the river to drop below minor flood stage (4 feet) by this afternoon.
However, flood advisories and warnings are still in effect for areas of Sheridan County as the Powder River near Arvada is still rising.
Flows in the area increased from approximately 1.89 feet at 6:30 p.m. Sunday to a peak of 6.05 feet at 10 a.m. Monday.
Those near Arvada are under a flood warning until 2:30 Thursday afternoon as waters in the Powder River southeast of Sheridan will continue to rise.
The most recent data available has the Powder River at 9.76 feet at 6:30 a.m. Wednesday, but a forecast issued by NOAA Tuesday suggests the river will crest between 10 and 12 feet at Arvada Wednesday afternoon.
The National Weather Service in Billings suggests ranchers in these areas move livestock and equipment to higher grounds.
Sheridan County Emergency Management Coordinator Dave Coleman said this morning that he and his team examined potentially impacted areas near the Arvada area Tuesday to prepare residents for the flows. However, he said, as long as there is not a large influx of precipitation in the coming days, structural damages will be minimal if they occur at all.
“It doesn’t look like anything is in real danger out there (near Arvada),” Coleman said.
Sheridan County may not be out of the woods yet, though, as more rain is forecast for the week. A chance of thunderstorms is forecasted for today along with a 60 percent chance of showers Thursday through Friday.
