'3' No vembe~9, 19ii3 <br />4. The operator states in the November 23, 1983 response to MLRD item <br />No. E-5 that irrigation will not be done in any of the areas since the <br />• catt y rangeland proposed should not require irrigation. The staff would <br />recommend that the Board drop this original permit commitment for upland <br />areas which are definitely grazing land, however, meadow areas adjacent. <br />to the creek should be seeded with the hay meadow mix and irrigated until <br />established. <br />5. It is the staffs understanding that the operator will agree to <br />grading bottom lands adjacent to the creek such that drainage would be in <br />a generally downstream direction, rather than allowing drainage directly <br />back to the river. <br />6.

Did the operator alter the course of the Saint Urain Creek? If so, <br />what was the date of the channel change? Please address the benefit of <br />putting the Saint Vrain Creek back into its original channel and filling <br />that portion of the stream channel that was constructed. Please keep in <br />mind that a 404 dredge and fill permit would be necessary to backfill <br />this wetland. <br />E. Exhibit L - Reclamation Costs <br />1'.
