Since that time, the lake, which now occupies <br /> <br /> <br />176.5 acres of a 290 acre Denver park, has been and continues to be a <br /> <br /> <br />valuable recreational resource for the rnetropol itan area. In addition <br /> <br /> <br />to its scenic and recreational significance, the lake provides the very <br /> <br /> <br />important function of regulating and control I ing dmvnstrealll fJOIvs that <br /> <br /> <br />otherwise would be allowed to run uninhibl ted through west Denver. <br /> <br />TO .."ofCCL'.... <br /> <br /> <br />-------._~-" "" <br /> <br />AaCKY "'OUNT"'" "AS""AI- <br /> <br />I <br /> <br />I <br /> <br />I <br /> <br />. . ~ <br />. <br /> <br /> <br />I <br /> <br />. <br /> <br />Since the Basin Is heavily urbanized, the major drainageways are not <br /> <br /> <br />clearly identifiable, Most of the major historic drainage channels have <br /> <br /> <br />either been filled In or built over to the point of obliteration. Where <br /> <br /> <br />open drainageways do appear, vegetation Is usually well controlled and <br /> <br />reflects the completely urbanized nature of the overall Bas in. Soi I con- <br /> <br />ditions tested In the vicinity of Sloans Lake revealed that the material <br /> <br /> <br />above the existing water table, measured to be between 7 and 11 feet below <br /> <br /> <br />ground level, was fairly sandy and granular. 5011 below the local water <br /> <br />table was a heavy clay with a classification of A-6(lO) in the AASHO <br /> <br /> <br />standards. <br /> <br />-.- <br /> <br />ADAMS COUI <br />.wa..
