Reservoir Station File (*.res)
The reservoir station file contains information to describe the physical properties of each reservoir in the system. Reservoirs may be operated such that they 
will not (iressw = 1 or 2) or will (iressw = 3) divert above their target. When a reservoir stores above its target and subsequently releases that water as part 
of an operating rule, the net result is a paper fill which is charged against the reservoir right’s one fill limitation and additional water becomes available 
downstream of the reservoir. This file is read by subroutine GETRES.

Enter station ID (cresid) if daily data will be provided for this station. Monthly data controls. | 
||
| Enter another station ID to use the daily distribution of another but weight values by the monthly total in the reservoir target (*.tar) file or reservoir end-of-month (*.eom) file. Monthly data controls. | ||
| Enter 0 to use the average daily value from the monthly data in the reservoir target (*.tar) file or reservoir end-of-month (*.eom) file. Monthly data controls. | ||
| Enter 3 to use the daily value from the daily reservoir target (*.tad) file or reservoir end-of-day (*.eod) file. Daily data controls. | ||
| Enter 4 use a daily pattern developed by connecting the midpoints of monthly data. Monthly data controls. | ||
| Enter 5 to use a daily pattern developed by connecting the end points of monthly data. | ||
