As of February 15, severe /D2/ drought conditions are located across most of Harding, Perkins and Butte counties, the northern and western portion of Meade County as well as southern Fall River County and southwestern Shannon County. Elsewhere in South Dakota, moderate /D1/ drought conditions covered the rest of Shannon and Fall River counties, as well as, Pennington, Custer and the western halves of Ziebach, Haakon and Jackson counties. Abnormally dry /D0/ conditions exist across Bennett County and the eastern portions of Jackson, Haakon and Ziebach counties.
In northeast Wyoming, moderate /D1/ drought conditions cover Weston County and abnormally dry /D0/ conditions exist across Crook County and southern and eastern sections of Campbell County.
During the month of January temperatures were near average, while precipitation averaged 10 to 20 percent above average. The slightly above average precipitation and season temperatures helped to keep drought stricken areas from becoming worse.
During the first half of February precipitation was above average and temperatures were below average.
Snow cover so far this winter season has been around average for most areas across the plains of northeastern Wyoming and western South Dakota. The northern Black Hills and Bear Lodge Mountains have seen slightly above average amounts, while the southern Black Hills have recorded amounts at or slightly below average. Snowfall reports from the Cheyenne, Belle Fourche, Grand and Moreau river basins have so far been below average.
The forecast through March 2008 continues to indicate persisting drought across western South Dakota and northeastern Wyoming.
Moderate to strong La Nina conditions are expected to continue through the spring of 2008. The Climate Prediction Center outlook through March calls for above average temperatures and near average precipitation. However, drought conditions are likely to persist since average precipitation for March is 0.75 to 1.25 inches on the plains of western South Dakota, the plains of northeast Wyoming and over the southern and central Black Hills. In the northern Black Hills and Bear Lodge mountains, precipitation averages 1.5 to 2.5 inches for March.
According to the United States Geological Survey /USGS/, the recent water resources conditions for February indicated the monthly-average streamflow was normal.
Reservoirs around the region remain below average for this time of year. The table below shows reservoir percent of average capacity and change in elevation over the past 30 days as calculated by the United States Bureau of Reclamation (USBR).
|Reservoir||Percent of Normal||Elevation Change|
|Belle Fourche||47%||+1.8 ft|
