The report will <br />focus on the findings of a recently completed study designed to evaluate <br />the relative abundance, movement and habitat use of Colorado squawfish and <br />razorback sucker in the 15-mile and adjacent reaches throughout the year. <br />Data collection for this study was conducted from May 1986 through Decem- <br />ber 1988. Data collected during previous studies by Valdez et al. (1982) <br />and Archer et al. (1985) were employed where appropriate. <br />3
