Map of below normal 7-day average streamflow
compared to historical streamflow for the week of the year (South Dakota) |
|
The Below normal streamflow map depicts 7-day average streamflow conditions as measured at USGS gaging stations. The colors represent 7-day average streamflow compared to percentiles of historical weekly streamflow for the week of the year. |
This map represents conditions adjusted for this time of the year. Only stations having at least 30 years of record are used. |
Uncolored circles depict stations having less than 30 years of record, having streamflows near or above normal, or that are currently not transmitting. |
The data used to produce this map are provisional and have not been reviewed or edited. They may be subject to significant change. |
