Gary Lacy, Breckenridge Whitewater Course Design Engineer, v VIII, p. 7 <br />Q Mr. Lacy, in designing the course for 500 c.f.s, what type of techniques <br />did you use to optimize the structures for 500 c.f.s. and what I mean by <br />that, what physical characteristics were you modifying. <br />A Well, I modified a number of things, primarily the stream channel width. <br />It was necked down or narrowed to force the water through a narrow <br />opening so that was one primary effect. Another one was the stream <br />gradient so that a drop - - the uniform grade was cut into pieces where at <br />each drop there was a certain amount of vertical drop that the water was <br />forced over at each drop. <br />The course was designed to create the whitewater features that attract boaters <br />Gary Lacy, Breckenridge Whitewater Course Design Engineer, v VIII, p.19 <br />Q ... [W]hat purpose does the high flow channel serve for the Whitewater <br />Park? <br />A Well, that high flow is when the most boating occurs and that's what <br />creates the whitewater features, so by constricting the whole river though <br />that high flow portion, and forcing it over the structure into the pool <br />downstream, that interface is what creates the waves and holes that are <br />conducive to the sport. <br />Course construction modified the stream channel <br />Gary Lacy, Breckenridge Whitewater Course Design Engineer, v VIII, p.9 <br />Q ... [J]ust ... give a general description to start with. <br />A Well; I guess they're structures that are - - they extend all the way across <br />the entire stream channel, anchored well into the bed of the river and into <br />the banks. They are well - - strongly anchored for stability. <br />Q So they do span the entire width of the stream. <br />A Yes. <br />Q You said they're anchored deep into the stream bed. How far into the <br />streambed do they go? <br />As0007 -5- <br />
