1.13, p.12,1.12 -17). The Park is comprised of three rock structures that were built with 1600 tons
<br />of imported rock anchored a minimum of fifteen feet into the stream bank and six to eight feet
<br />into the stream bed, (v.XI, p.11, 1.14 - p.12, 1.8), with boulders up to eight feet in length,. (v.XI,
<br />p.16,1.18-20). Because it was important to the Town for the structures to look as natural as
<br />possible, no grout was initially used. (v.XI, p.12,1.9 -17; v.X, pp.50 -51). Rather, Mr. Lacy used
<br />a technique of jigsaw - piecing the boulders together and pounding sand into the spaces between
<br />the rocks. (v.XI, p.12,1.18 - p.19,1.7). Once completed, each structure operated as a single unit
<br />to create the desired whitewater features and are as durable as structures Mr. Lacy has built using
<br />grout. (v.XI, p.13.1.9 -26).
<br />C. The Structures Control Flows to Create the Intended Whitewater Features
<br />Dr. Jeris Danielson, the former State Engineer, and Alan Martellaro, Division 5 Engineer,
<br />both confirmed Mr. Lacy's testimony that the structures change the water's direction, velocity,
<br />depth, and horizontal and vertical planes. (v.XI, p.100,1.19 -21; v.XII, p.33,1.16 - p.35,1.5). The
<br />structures have low flow and high flow channels or chutes to control and concentrate water to
<br />form holes, waves, jets, and eddies, the desired features necessary for whitewater boating. (v.XI,
<br />pp. 19-20, 29 -30, 36 -39). The structures control water efficiently, and without waste by
<br />controlling the entire amount of appropriated water for the intended use without any loss or
<br />consumption. (v.XI, p. 45,1.20 - p.46,1.4; p.105,1.4 -19). The control, lack of overtopping, and
<br />weir formula calculations used in the design were all field verified. (v.XI, pp.19, 22 -24, 26). As
<br />flows increase up to 400 c.f.s. or more, the best and most attractive waveforms are created.
<br />(v.XI, p.43, 1.13 -18). Vail approved modifications to the three structures (including the use of
<br />grout for one structure) that will further enhance and improve the whitewater features. (v.XI,
<br />pp.32 -34, 70; v.X, p.40,1.16 -19).
