Selected Water Discharge Data from Norfork and Bull Shoals Dams
The data contained below is a portion of the data collected from the Little Rock District of the Corps of Engineers as linked from the Ozark Hydro-thon web page. Times have been converted to Universal Time (UT) for consistency of comparison to datalogger data that is part of the GLOBE Program dataset. In order to estimate the effect of any amount of water released, a travel time has been added to the release time and the joint effect of both discharges is estimated in cubic feet per second at the bottomland datalogger site in the rightmost column below. A two hour travel time has been added to the Norfork Dam releases and a twelve hour travel time has been added to the Bull Shoals Dam releases.
Thus the following formula is being used to calculate the
discharge event at the datalogger site.
Norfork Dam release time + 5 hr (CDT)
correction factor + 2 hr travel time = Norfork Releases
Bull Shoals Dam release time + 5 hr (CDT) correction factor + 12 hr
travel time = Bull Shoals Releases
Norfork Releases + Bull Shoals Releases =
Combined Releases
