There are two comma-delimited data files XS_WSE.csv and Ref_HP_Pro_Coord.csv.  
Each has a single header line with data beginning on line 2.  Entries that are 
not applicable are left blank with the columns organized so that potentially 
blank entries always occur at the end of a row.

Ref_HP_Pro_Coord.csv contains coordinates of reference points, head pins, and 
thalweg longitudinal profile points.  Fields from left to right are

Type where 	REF=reference point
		HP=head pin (virtual at ground surface)
		ProMain=longitudinal profile thalweg point along main channel
		ProSide1 = longitudinal profile thalweg point along side channel 1 
		ProSide2 = longitudinal profile thalweg point along side channel 2
		ProSide3 = longitudinal profile thalweg point along side channel 3
Name = unique point name
Northing = northing horizontal point coordinate in UTM12N from datum NAD83[99]
Easting = easting horizontal point coordinate in UTM12N from datum NAD83[99]
Altitude = vertical point coordinate in UTM12N from datum NAVD88
XS = cross section number for head pins (1 to 30)

XS_WSE.csv contains dimensions of cross-sectional topography and water-surface 
elevations.  Points representing ground and water surface at specific discharges 
are represented relative to a line from left (looking downstream) to right head 
pin with an origin (coordinates of 0,0,0) at the left head pin.  Fields from 
left to right are

Type where 	HP=head pin (virtual at ground surface)
		XS=ground topography
		XSED=edited ground topography created from virtual head pin point
		WS=water-surface elevation
WSED=edited water-surface elevation created from other water-surface point
Name = unique point name
Station(m) = distance in meters along line from left to right head pin
Offset(m) = offset in meters of point from station line (negative is downstream)
Elevation(m) = vertical distance in meters relative to 0 height of left head pin
XS = cross section number (1 to 30)
Q(cfs) = discharge in cfs for water-surface elevation points
