display, the program repeats steps 2-4 for each
additional TRF diversion category (table 5).

6. When the account changes for all TRF di version
categories are completed, the program writes the
updated account values to the aee/.fil file and
then returns to the program options.

Data Input

Data input has three major components: input
of the TRF and native return-flow discharge data,
input of the gaging-station discharge data, and input of
the NSF and TRF diversion data. These data are
compiled daily from various sources by the water
commissioners prior to using the accounting program
for a transit-loss computation. The program operation
relating to the data input is described briefly in the
following sections.

Return-Flow Discharge Data

To input the TRF and native return flow, the
program uses a simple display to query the user for
each return-flow quantity: (I) The TRF at the CCS
WWTF, (2) the native return flow at the CCS WWTF,
(3) the Fort Carson TRF, (4) the FAP TRF at the CCS
WWTF, and (5) any supplemental TRF released
upstream from the CCS WWTF. The program then
displays all the return-flow data that were input and
queries the user if the data are correct. If the response
is no, then the program repeats the return-flow
discharge data input; if the response is yes, then the
program proceeds to the input of the gaging-station
discharge data.

In the current (1997) version of the accounting
program, the user is not queried to input TRF data for
the Fountain, Security, and Widefield WWTF's
because these data are not yet available. Therefore, the
program sets the TRF discharges for these three
WWTF's to zero; these sites, however, are included in
the display of the input data and in the daily output
files (table 5).

Streamflow-Gaging Station Discharge Data

The input of the gaging-station discharge data is
very similar to the input of the return-flow discharge
data. The program queries the user to input the daily
mean discharge at each gaging station (fig. 3), displays
all the input data for error checking, and repeats the
data input if any errors were made. When the input
data are correct, the program proceeds to the input of
the di version discharge data.

Diversion Discharge Data

Diversion discharge data can be input for NSF
diversions and for three categories of TRF diversions.
Inpul of the diversion data is similar to the program
steps described in the "Option 4" section for updating
the diversion accounts data. Input of the diversion
discharge data begins with the NSF diversions: the
program lists the diversion data from the last computa-
tion date, as shown in the display at the bottom of this
page.
If the response to the display query is yes, the
program operation is like step 3 of the "Option 4"
section (p. 32); the program (I) queries the user for the
IOtal number of diversions to change, (2) que,ries the
