While the temporary diversion is being constructed, same <br />water will be allowed to flow past the diversion in the <br />eristing channel at the same time water is directed into the <br />Fhase I area. This will allow the Fhase I channel to become <br />saturated as water flows northward to where it will re-join the <br />existing channel. The quantity of water in the main channel <br />will be temporarily decreased while this flow is <br />re-established. This will be done in early spring or late fall <br />when flaws are slightly higher than in winter, but not during <br />irrigation season when there is a greater demand by downstream <br />users. <br />To assure that the quality of the groundwater is ^t ~ <br />adversely affected by the proposed ^peration5 water sampling <br />o the Webb we 1 has been started so that baseline data is <br />avai able. The Webb well will be routinely sampled.

As described in Item 4 above, the proposed diversions <br />will be scheduled at times when the river volume is slightly <br />higher than normal, but at times when demands of irrigation do <br />not exist. The month of April has mean flows twice those of <br />• ~ the winter months, but is prior to the high flows of May to <br />June and is also before the irrigation season. The months of <br />September and October also have flows higher than in the winter <br />and are also at a time when the irrigation demands are <br />decreasing or have stopped. <br />7.

The east boundary of the permit area is in the center <br />of the historic high-water channel as indicated on Exhibit E - <br />Map. Since the boundary of the Fhase II excavation has been <br />moved so as not to disturb the mature cottonwood trees along a <br />portion of the boundary, riprap will be placed along the <br />excavation near the trees as indicated on Er.hibit E - <br />Reclamation Flan Map. A rail/wire structure will be placed <br />along the east boundary, from the southern permit boundary to <br />this riprap for additional erasion control. <br />10. Please refer t^ Er.hibit E - keclamation Plan Map. <br />11. The present river channel on the north end of the <br />property is in a direct line with the Fhase I excavation and <br />• the flow will be directed to this channel as the river is <br />diverted for Phase II. As discussed at our on-site meeting <br />January 16, 1992, it would be advantageous to keep the flow of <br />Page 4 <br />
