This study was conducted with the objectives of
arriving at an understanding of the distribution
and species composition of fish in Piceance
Creek as they exist today. The introduction of
numerous fish species from other drainages and
less obvious effects such as aggricultural
diversions and riparian alterations have produced
changes in the fauna of Piceance Creek. Any
future extensions of the ranges of the various
species, changes in species composition, or
notable changes in number of fish per length of
stream may be identified through use of these
background data.

Navajo Unit; invertebrate surveys of
Navajo Reservoir tailwaters. Job Completion
Report, Section 8 Project/Job No. A-4(b).
The data presented in this text include those
collected during the years 1963, -64, -65, and
-66. The invertebrate studies were submitted
as a separate report rather than being included
with the segment report. It is, however, a
part of the fisheries investigation project on
the Navajo Reservoir tailwaters. Ephemeroptera,
Trichoptera, Diptera, and Gastropoda were the
most common orders of bottom organisms found.
The dipterans were the most abundant organisms
found and occurred in large numbers at-Stations
A and D. The number of organisms collected per
square foot showed a progressive decrease in
numbers at each downstream station. Station A
had the largest number collected per square
foot while Station H had the least.
