150 mg biomass per cubic meter in the monitoring data for CB20H, that would be 
[150 mg/m A 3] * [1,237,000,000 cubic meters in Segment CB20H] = 1.86 A 11 mg 
biomass in the Segment CB20H, which is close to the interpolated value of 
1.326 A 11 mg, above. 
Data from one job to another may be appended to the same output file so that a time 
series file is created that can be opened in a spreadsheet or database program for 
further graphing or analysis. The first line of the file is composed of ‘column head¬ 
ings’ contained within quotes. This file can be edited as necessary by the user. The 
file structure is: 
Line l>Column headings defined by the ‘Report’ job that is run, including data start date, data end 
date, depth of top layer analyzed, depth of bottom layer analyzed, mass of parameter by 
segment.repeat for each segment.grand total mass 
Line 2>data accumulated from the input interpolated file (.est) for each column in line 1 
Repeat for each interpolated file processed. 
Note: Since data that are calculated may be appended to an existing file, there is a 
risk that the user may append data from different bathymetry jobs. The user must be 
careful not to mix 8 segment mainstem data with 77 segment mainstem and tributary 
data in this report, or else the column headings will not represent the data.
