Bushong, Esq. <br />PORZAK BROWNING & BUSHONG <br />929 Pearl Street, Suite 300 <br />Boulder, Colorado 80302 <br />Dear Mr. Bushong: <br />This is a follow -up letter to my December 8, 2000 report regarding the water <br />rights application filed by the City of Golden for,the Whitewater Course on Clear Creek <br />to respond to issues that have been raised, including those contained in Mr. Craig <br />Green's report dated January 15, 2001, and others. <br />The high flow rate that the course was designed for (1000 cfs) was based <br />on basic hydraulic formulas coupled with a working knowledge of this segment of Clear <br />Creek and its natural characteristics. These hydraulic formulas provide the parameters <br />for each structure, then are modified to create a structure which produces a certain <br />waveform at high flows. These structures are hydraulically, and structurally sound, with <br />anchors into the bed and banks of the creek with large stone and concrete. I may <br />testify in more detail regarding design information, if necessary. <br />The Clear Creek Whitewater Park Is clearly a success. A number of large <br />regional, national and international events have been held on the site during its short <br />history. These events include the popular Clear Creek Whitewater Festival, the.Open <br />Course Nationals, the Junior Olympic Trials and the Eddie Bauer International Slalom <br />event. It has also been featured in numerous newspapers and magazines, and has <br />been a topic of Internet sites. Primarily, its high use for many boaters and its reputation <br />make it a popular attraction for the City of Golden. <br />• The structures built within the Clear Creek Whitewater Course are <br />significant hydraulic improvements to what previously existed that completely divert and <br />control the streamflow. These structures are large structures, built of large stone <br />grouted together with concrete, span the entire channel, and are anchored well into the <br />bed and banks of the creek. They are designed to divert and control the high- flows to <br />create whitewater boating features, particularly at high flows. These structures function <br />to control the water to form water features, even if they are partially or completely <br />EXHIBIT <br />a <br />� G -51 <br />
