Components of the surface water modelling and calculations made by the Applicant as part of this case in support of the Application, were also analyzed. Such analysis revealed quantitative estimates of stream flow which have also played roles in the Applicant's ground water model within the same South Park system. Figure 7-1 illustrates the surface area and stream features represented in the surface water model. Surface topographical features extracted from the USGS' DLG have been superimposed upon this and other figures which follow, as appropriate for clarity. Figure 7-2 presents a close-up view of the area of concern depicting the flow sectors defined in the surface water model.

Summaries of water rights information included in this model for each of twenty-eight flow sectors are depicted in a sequence of images from Figure 7-3a through 7-3z together with 7-3aa and 7-3bb. Each figure in this sequence identifies the spatial location of a designated flow sector, i.e. by name and a numerical identifier, and presents a table of water rights within it. The boundary of the Sportsmen's Ranch property is also identified in each figure of the sequence.

Figure 7-4 depicts the spatial locations of streams and ditches as represented both in the ground water model, via model stream grid cells that are identified, and the surface water model, via flow segments and paths which are also identified. The irrigation and diversion rights represented in the surface water model are also included, for clarity. The collection points, identified in these figures by alphabet characters A through J, of the proposed North Branch surface water collection ditch are also indicated for clarity. The grid cell arrangement of the ground water model are also identified by their numbering, as designated by the Applicant, included on both axes of this figure.

A sequence of thirty images which follow, from Figure 7-5a through 7-5z together with Figure 7-5aa through 7-5dd, present stream flow rates for ground water model segments designated in the stream package of the Applicant's ground water model. This sequence of figures is intended to present a comparison between the stream flow rates supplied to the ground water model by the Applicant, by month and year of model simulations, with the corresponding values employed in the surface water model for the same stream segments. Values employed to simulate both the NOCUP and the SPCUP conditions are presented in separate hydrographs employing the same scales. The location of the affected segment is clearly identified in a cameo map of the area that is also included in each figure. The differences between the two representations of available stream flow rate for the identical stream segment may be observed in each figure of this sequence.

Last but not least, a sequence of nine graphical images from Figure 7-6a through 7-6i present a comparison between measurements of actual stream flows based upon available gauge records and representations of stream flows in the Applicant's surface water model. The incompleteness of available measurement records, and their significant variability at daily frequencies, may be observed in these figures.
