I. Title of Proposal:

INTERAGENCY STANDARDIZED MONITORING PROGRAM (lSMP) ASSESSMENT OF
COLORADO SQUA WFISH REPRODUCTION AND LARVAL ABUNDANCE IN THE
LOWER YAMPA RIVER, COLORADO, AND THE LOWER GREEN AND COLORADO
RIVERS, UTAH.

II. Relation to Recovery Program and RIPRAP:

Reproduction and recruitment of early life stages are critical components of the life history of
endangered Colorado squawfish. Understanding trends in reproductive success may help define
status of Colorado squawfish in specific river reaches in the Colorado River Basin and should play
a role in determining when recovery has been achieved.

Annual assessment of Colorado squawfish reproduction and larval abundance (this study) is
necessary to identify and assess factors affecting annual recruitment, and is directly linked with
many Recovery Program activities such as discharge management and control of non-native fishes.
