# = Station out of service ^ - estimated (7 hours or less available) ? = Avg. includes estimated data! = 17 hours or less of readings & = 18 to 23 hours of reading ND = No hourly readings or incorrect 

Control Point: Balls Ferry 3/1/2011 to 5/31/2011; Jelly's Ferry 6/1/2011 to 10/31/2011.NOTE: On 7/19/2011 the probe for SHD was extended farther out into the river so at low flows

 it should no longer be exposed to the air. 8/2/2011 the extended pipe floated away.  Some hourly readings for SHD may be questionable again and may be estimated.
