species. The northern leopard frog is listed by the CDOW as a species of special concern.
Surveys conducted in late May detected numerous frogs. However, it was difficult to identify
many of the observations due to the thick grasses along the banks of Reed Wash. Most of the
frogs escaped into the water before identification could be completed. However, bullfrogs were
identified and based on the smaller size of many of the other frogs that were flushed, it is
suspected that northern leopard frogs inhabit Reed Wash.
3.5 AQUATIC WILDLIFE
3.5.1 Fish: The main branch of Reed Wash headwaters begin southeast of Highline Lake.
Other tributaries include Peck and Beede Wash and the East Branch of Reed Wash. Three other
small, unnamed washes contribute to the flows in the wash. Water in Reed Wash is augmented
substantially by irrigation returns flows and ground water generated by irrigation of agricultural
crops in the Grand Valley.
Since 1996, Reed Wash has been sampled by the CDOW seven times. Electrofishing survey
results show 13 species of fish have been identified in the drainage (CDOW 2010b) (Table 9).
Roundtail chub, a CDOW species of special concern, has been identified and Flannelmouth
sucker is a BLM sensitive species.

Threatened and Endangered Fish: The point where the proposed rail spur crosses Reed Wash
is approximately 0.25 miles from the main channel of the Colorado River. Four federally listed
endangered fish (Colorado River fishes) species may potentially occur in the Colorado River and
Reed Wash, including the Colorado pikeminnow (Ptychocheilus lucius), razorback sucker
(Xyrauchen texanus), bonytail (Gila elegans), and humpback chub (Gila cypha). The
pikeminnow and razorback sucker are CDOW listed threatened species and the bonytail and
humpback chub are state endangered species.
