Current composite radar loop above. Below is zoomed FSD N0Q
hi-res radar at Sioux Falls, Wundergages, and
adjusted N0Q at watersheds. Note that the raw N0Q radar here almost always
shows "ground clutter" because of being so close to the radar site. Ground
clutter (0.05" to 0.1" a day) is just another simple matter that rain gage
adjustment removes. No rain at the rain gages for the hour then no radar rain.
The rain gages are not heated so MRSM-A2M radar product is being tested this
winter. The rain gages appear to match the A2M totals when they thaw out
the next day or two.
The
23.9 sqmi Willow Creek basin was not subdivided and the USGS gage is 06481497
WILLOW CREEK NEAR CROOKS, SD. The basin boundary was digitized using
Google Earth Pro Add Polygon method and saved as a KML file. My
GoogleKML2Text.exe program then converts the kml to text for my
LatLongPixelsFromFile.exe that creates the GetRealtime basin boundary pixels.
These programs are free on my Help web page from the top menu above.
The USGS does not provide flow values, just stage in cooperation with the City
of Sioux Falls. They have made a couple flow measurements a year since
2001 and are subject to heavy vegitation and ice. I constructed a flow vs
stage table for lookups of the USGS provided stage.
Annual peak FLOWS are also provided since 2001 and I created a Log Pearson III
annual propability distribution of the peaks for use for reporting peak flow
recurrence. I also got the NOAA Atlas 14 partial probability rainfall
depths for reporting the 5-min to 3-day recurrence of rain depth.
