<br />e <br /> <br />e <br /> <br />e <br /> <br />SURVE:'( <br />GREENWOOD VILLAGE <br />AQUATIC RESOURCES <br /> <br />. <br /> <br />At the request of the city government of Greenwood Village the Colorado <br />Division of Wildlife (COOW) performed a qualitative survey of the drainages <br />flowirg through the cannunity. Goldsmith Gulch, Greenwood Gulch, Little Dry <br />Creek and Big Dry Creek were surveyed at one or two locations. The object was <br />to describe in a qualitative manner the aquatic invertebrate and fisheries <br />populations found in these drainages. Fish were sampled using a backpack <br />electrofisher. Invertebrates were picked from the stream bed by hand and <br />identified. Field work was done in ~~y and June of 1984. <br />All the streams examined were fourd to contain aquatic life. Although <br />fairly small and to varying degrees impacted by man these waters represent a <br />valuable urban wildlife resource. Other than the aquatic life identified, <br />waterfowl, kingfishers, common gallinule, other birds and tracks of mammals <br />associated with wetlands and riparian areas were observed. Although outside <br />the scope of this survey the value of wetlands ~source found in these <br />drainages was addressed in detail in the "8elleview Avenue Final Impact <br />Statement" prepared by the Colorado Department of Highways, 1982. Animal <br />species present are cataloged on page 19 of that doc~ent. <br /> <br />e <br /> <br />e <br /> <br />GOLDSI~ITH GULCH, tributary to Cherry Creek, drains the eastern portion of <br />Greenwood Village. The gulch was sampled first at the t,eadwaters just outside <br />the southern limits of Greenwood Village. A fairly extensive wetlands, with <br />cattail covering the streambed, was present. Fathead minnows, Pimephales <br />promelas, were abundant in the shallow, slow-flowing, sand bottomed stream. <br />Several Dipteran midge larvae (Chironomidae) were also observed. <br />Goldsmith Gulch was also sampled above and below Orchard Hills Pond in <br />Greenwood Village. A wetlands area of cattail had been removed leaving a <br />straight flowing stream channel edged by a bluegrass lawn. No fish were found <br />although crayfish, buffalo fly (Simulidae) and Chironanidae were taken. Any <br />fish that were present would probably have been eliminated by the cattail <br />removal procedure. Small bluegill (about 1.5 irches) are taken from Orchard <br />Hills Pond. Preserce of young bluegill indicates the speCies had successfully <br />spawned in the pond in 1983. <br /> <br />GRJ::ENoIOOD GULCH was sampled in two lcx:ations. The first was near the <br />headwaters at approximately Orchard Street and Orchard Drive. The stream has <br /> <br />e <br />
