Maximum Denver depletions are assumed which <br />generally produce the worst case scenario of flows during model Simulation. <br /> <br />The hydrology model uses net inflow to Dillon Reservoir. The model does not <br />simulate conditions on the upstream tributaries flowing into Dillon <br />Reservoir nor does it extend below the Cameo gage on the Colorado River. <br />The det~iled hydrologic analysis required for NEPA compliance above Dillon <br />Reservoir and below the Cameo gage will be accomplished outside of the <br />actual computer model. This analysis will be compatible with the model and <br />will bean extension of the model output. <br /> <br />All individual water sales are considered net depletions associated with the <br />exception of snowmaking by the hydrology model. Snowmaking diversions and <br />returns are identified separately in the data base. The amount of water to <br />be contracted for is assumed to be the net depletion to the Colorado River. <br />Consequently. individual users will each be required to obtain an augmen.; <br />tation plan approved by the Colorado State Engineer with the Green Mountain <br />Reservoir contract water as the required augmentation supply. Water sales <br />from Green Mountain Reservoir will be available solely to West Slope users <br />and only up to the amount of water hydrologically required to augment their <br />out of priority depletion to the Colorado River. <br /> <br />Storage' in Dillon Reservoir. inflows to and storage in Williams Fork <br />Reservoir. and diversions through the Roberts Tunnel were not simulated by <br />the model. <br /> <br />A basic assumption of the model is that the combination of Roberts Tunnel <br />capacity and available storage in Dillon Reservoir coupled with extensive <br />
