more than 81 consecutive days in one stretch, and in considering the total number of days of <br />delivery, water was delivered only about 25% of the time. Based on this regimen of water <br />deliveries, the EPR can be considered ashort-term discharger, though not temporary. <br />The long-term water quality ramifications of the EPR deliveries must also be assessed, even <br />though the deliveries can be considered of a short-term nature. As identified in Table 5, the <br />water quality of the East Fork is not adversely affected by flow from the EPR. EPR water is of <br />sufficient quality to support a population of aquatic macroinvertebrates and fishes (a biotic <br />community was stocked in the EPR in August 1997 and continues to thrive today). Deliveries <br />from the EPR aze of the same quality as water at the surface of the reservoir and thus will <br />support similar aquatic fauna and recreational uses. As the macroinvertebra[e population in the <br />reservoir grows, the delivered water will supply additional sources of food to fish populations in <br />the East Fork and mainstem of the Eagle River. Increased flows in the East Fork, especially <br />during low-flow periods, and increased food supplies are benefits that should be taken into <br />account in considering the effects of the EPR water deliveries. <br />Water deliveries from the EPR are of a short-term nature and do not create an adverse change in <br />the water quality of the East Fork. Therefore, the deliveries can be considered not to result in <br />significant degradation of water quality using the temporary or short-term discharge significance <br />determination approach. <br />6601631.005 0101 0501 0380 7 <br />\boutdenbata\yrojeclsU9M1~ ciimax\epr repod~.doc <br />
