III, Project Summary:

The purpose of this project is to use standardized data collection
techniques to assess the status and trends in populations of endangered
Colorado squawfish and humpback chub in Colorado, Sampling is conducted
annua lly for 1 ate-juvenil e/adult Colorado squawfi sh populations in the
Colorado, White, and Yampa Rivers; annually for post-larval/Age 0
Colorado squawfish populations in the Colorado River; and every third
year for adult humpback chub in the 8lack Rocks area of the Colorado
River, Length, weight, and tag data are collected for all late-
juvenile/adult squawfish and humpback chubs handled.

IV, Study Schedule:

A, Initial year: 1986
B. Final year: ongoing

V, Relationship to RIPRAP: General Recovery Program Support Action Plan,
Task V,A,I. - Conduct standardized monitoring program,

VI, Accomplishment of FY 94 Tasks and Deliverables, Discussion of Initial
Findings and Shortcomings:

A, Tasks, Deliverables and Accomplishments:

1. Conduct 1 ate-juvenil e/adult Colorado squawfi sh monitori ng in the
Colorado, White, and Yampa Rivers by electrofishing. Record data
from all Colorado squawfish, check for existing tags and PIT tag new
fish. Colorado River - 5 CS captured, I CS observed. White River -
13 CS captured, 6 CS observed. Yampa River - 14 CS captured, 2 CS
observed.

2, Conduct late-juvenile/adult Colorado squawfish monitoring by trammel
netting all backwaters on Yampa River in ISMP reaches. Record data
from all Colorado squawfish, check for existing tags and PIT tag new
fi sh, One Colorado squawfi sh captured by trammel netting. Water
levels in backwaters were very low. Three CS captured by
electrofishing in river.

3, Conduct post-larval/Age 0 Colorado squawfish monitoring in the
Colorado River, Record habitat data for backwaters and obtain fish
