Structure Summary File (*.xss)

The Structure Summary File (*.xss) is a standard output when the variable efficiency option is used (control variable ieffmax = 1). The report describes structure data related to area, demand, maximum efficiency surface water use, ground water use, soil storage, consumptive use and returns. It was developed to provide data similar to that provided by StateCU, the State's consumptive use model.

The header describes the structure (diversion or well ID), account and name. In addition, it describes the administration number, on/off switch, owner, and decreed amount for each water right located at this structure. It then contains a time series for the following:

# Column Description
0 Structure ID Structure ID (diversion or well)
0 Year Year of the simulation
0 Mo Month of the simulation
1 Sw Fld Acres served by surface water and flood irrigation
2 SW Spr Acres served by surface water and sprinklers
3 GW Fld Acres served by ground water and flood irrigation
4 GW Spr Acres served by gronnd water and sprinklers
5 Total Total Acres
6 Total Demand Structure Demand provided in the demand files. Note if demand data is provided as a consumptive value total demand is adjusted using a surface water efficiency.
7 CU Demand Consumptive Demand. Note if a consumptive demand file (*.ddc) is provided this value is printed. If a consumptive demand file is not provided this value is calculated from demand and efficiency data.
