2983 . . the Narrows Unit an attempt was made to evaluate the amount of return flow whiohwould develop in various reaches of the stream. These evalu- ations were used as a basis for estimating the amount of water available for senior appropriators and the demands for supplemental water that might be antioipated at Narrows. 8. Question: Assuming that direot priorities above the reservoir have been supplied their priorities, and next senior direct priorities are below the damsite, in cases where freshets or small raises appear in trte river, wha. t is the Bureau's proposal as to passing t,;is water through the reservoir? Answer: As st;ted under No.7, river administration by the state Engineer or his representatives would only allow the storage in the Narrows Reservoir of that water whioh would belong to it under its relative priority. As nearly as possible, water which is not stora~le in the Narrows must be passed through the reservoir to restore to the stream, waters whioh should be there in the same rranner as they would have oocurred naturally. 9. Que~: rlave the Bureau investic;ators for this projeot become fully famil iar with the wa tar ri{';hts on the South Platte River, partiou- larly with reference to tlle practical, actual operation, the limitation of time and oapacity" Are they familiar with proposed improvements, con- ditional deorees, and added use of water by present water users as addi- tional supplies beoome aveilable" Answer: On many individutll details, the Bureau investigat'L's are perhaps' not as familiar as many of tlle people dealinc; intimately on a day'to day. basis with that particular detail. On a koad, overall basis, it is believed the bureau investigetors are as compBtent and are as familier as anyone faced with the study of the same problem could be. As has previously been stated, Narrows must operate within the State law and the decrees and appropriations of water as recognized by the courts. Such decrees are all a matter of record and the system of river administration as practiced in Colorado is well known. 10. Question: Would the Bureau recognize the right to refill reser- voirs as has~ oustomary in the past after present decrees have been satisfied? Answer: As has been previously stated in answers to many questions "bove, the Bare au would operate the Harrows Unit in accordance with State law and in accordance with the terms of the repayment contraot with the Northern Colorado Water Conservahcy District. However, it is pointed out that in the changed river regimen that will prevail ~fter the return flows from the Colorado-Big Thom:>son and Blue-South Platte Projects are stabilized, there should be sufficient water in most years to satisfy direct flow decrees. The demand for stored water from exist- ing reservoirs and the need for multiple fillings will greatly decrease or disappeflr. 10
