Application for Water Rights of the Eagle River Water& Sanitation District <br />March 5, 2002 <br />Alan C. Martellaro, P.E. <br />Page 40 <br />1 on where I said the -- what I think was a bike <br />2 path, I can't recall, it's been so long, but <br />3 that was submerged, there was an eddy in there. <br />4 Q. How would you describe the <br />5 differences in the flow of water as it passes <br />6 through the white-water courses as compared to <br />7 the flow of the water immediately upstream or up <br />8 river of those white-water courses? <br />9 A. I'm not sure I could respond on the <br />10 channel above the course, but below the course, <br />11 which I suspect would be similar to the way the <br />12 f low was before the course was constructed, the <br />13 depths are relatively uniform, the flows are -- <br />14 the velocities are fairly fast, probably not <br />15 conducive to boating in especially lower flows. <br />16 Q. And how do the course structures <br />17 change that? <br />18 A. The course structures reduce <br />19 velocities in places that creates a higher water <br />20 surface profile, and therefore a drop that <br />21 creates a wave downstream and appears to make it <br />22 boatable even in relatively low flows. <br />23 Q. Do the course structures deflect <br />24 water? <br />25 A. Yes. <br />I Esquire Deposition Services (303) 316-0330
