Based upon the need to provide water to meet the above composite crop demand, an evaluation was done of the effects of changing 100 AF of Home Supply Ditch water from agricultural use to municipal use and the effect that this use would have on n~turn flows to the stream. This evaluation is shown in Table 8 which is based upon Johnstown's cunent pattern of water use and return flows, and meeting the crop needs shown in Table 7. The evaluation shows that in a typical year after transfer (1982 was used for this example) return flows to the river through the municipal systems will exceed agricultural return flows by slightly over 20 percent. The municipal pattern of use will be such that municipal returns always exceed the surface and lagged runoff from agriculture. To balance agricultural returns at 35 percent of headgate diversions, requires the monthly return flows shown in Table 9 for all of the decrees of the Home Supply Ditch.
