I am writing as <br />a private individual and trot on behalf of any organization. <br />I am a practicing Civil Engineer in Durango, in private consulting practice for 19 years. My <br />practice extends to a broad range of issues concerning, land development [hit include <br />hydrology, flood plain analysis, river and stream protection, [low prediction and other <br />elements germane to the above Public Notices. <br />In addition, I am a recreational river user [hat is intimately familiar with the Animas River <br />through the area covered in the Public Notices. <br />I am very aware of the problems of the Animas River through the Animas Vallz:y, subject <br />of these Public Notices. <br />Dura~:go heeds rite snttd a+:d grave! products nvaiiable from the Animas River.

The level and character of the Animas River has been changed suhstantially during [he <br />course of the past 20 years. This change is directly attributable to the quantity of material <br />that has been taken from the river bed, and to the method in which it has be?n taken. <br />Removal of many acres of unrela[ed land can be documentzd [hrou~,h this proczs. <br />2. At least one old and well established irritation headgate has been undercut ar.d moved <br />upstream many times to the point that today, even 1/Z mile further upstream, water from the <br />river is not available to this old senior w•arer right (1VaHace Ditch). <br />
