Control Point: Balls Ferry 3/1/2011 to 5/31/2011; Jelly's Ferry 6/1/2011 to 1/31/2012NOTE: 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 are questionable again and are being estimated.
