been channelized and all cattails re~oved. in addition, a construction
company had a piece of heavy equipment in the creek above the saJlllling
location. The stream water was extremely mu:!dy ard a heavy load of silt had
covered the stream bottcm. Any aquatic invertebrate corrrnunity had been
eliminated by the silt and the water was too turbid to see any fish. A second
location was sampled downstream at a wetlands area just west of Holly Street.
The water \Vas still muddy ard tt-e slbtrate silt covered but fatt-ead minnows
were observed and collected.
The north aIlll of Greenwood Gulch was saJlllled at approxinately ~10naco and
8elleview. An extensive wetlards is present at this location. Although no
fish were taken an extensive bottom fauna conposed of Chironomidae,
dragonflies, two species of caddis fly larvae (Trichoptera) and scuds
(Gammarus) was observed. This productive wetlands probably has year round
flows, or at least isolated pools, providing wildlife habitat.

LITTLE DRY CREEK was s~led two blocks east of University and two blocks
north of Belleview. Canopied by cottonwood trees the stream flows through a
channel with an alternating series of riffles and pools. The pools have a
gravel and sand substrate while the riffle substrate was composed of stone
cobble. 8aetidae and Ephemerella ~ayflies, crane fly (Tipula) ard
Chironomidae larvae were very abundant. Creek chubs (Semotilus atromaculatus)
from 4-9 inches in length and white sucker (Catostomus c~ersoni) from 4-10
i.nches were collected. The male creek chubs and suckers were in breeding
colors. Two age groups of both species were present.

e

BIG DRY CREEK was sampled where Orchard Road crosses the stream. The creek
-- --
has dL.g a deep, narrow channel Ered with trees and shrubs. The strean bed is
about five feet wide with a gravel, sand substrate. Grassy undercut banks,
shallow ~ools and riffle areas provide habitat for invertebrates and fish.
Ephemerella and Leptophlebiidae mayflies, crayfish, Tipula, and Chironomidae
larvae are abundant. White suckers, creek ch.Jbs, and lc:n;jnose dace
(Rhinicthes cataractae) were collected.

As described above all four streams provide wildlife habitat and S4Jport
diverse aquatic communities. Greenwood Gulch and Goldsmith Gulch have
extensive wetland areas while Little Dry and Bi~ Dry Creeks are tree canopied,
lower temperature streams. All four waters can be utlized by the community of
Greenwood Village to enhance urban wildlife for the enjoyment of the
citizens. The creek chubs on Little Dry and Big Dry Creeks provide fishing
