"there was no <br />evidence of sloughing or tension cracking on the slopes and the stream has remained <br />nearly in the same path as it was after construction. Rip-rap material, in general, <br />appeared competent; however, some weathering was apparent in isolated areas. At the <br />time of the resurvey, a good vegetative cover was starting. <br />The enclosed Figure No. 1, Revision No. 1, shows the channel as it is now in <br />comparison with the originally surveyed channel. The only noticable change is in the <br />channel bottom profile. As can be expected, the bottom has assumed a near constant <br />slope throughout the diversion area and the mounds created by construction have been <br />eliminated. <br />If you have any questions or need additional information, please call. <br />Sincerely, <br />Steve Pgagnuson, P.E. <br />Mining Engineer <br />SDM/tl <br />cc: Jeff Fleshman <br /> <br />
