based on catch records ~ (Jones and Tyus 1985).;Similiar flows have been rov ded by BR and the Western Area P ower Administration since that time, and successful recruitment of the fish suggest that these flo towards ws can aid management recovery. Several methods were emploged to evaluate the accuracy of the flow recommendations. ~ ~ ~~ Survival of young Colorado squawfish was eva ~O e 0.

These data indicated that recruitment was high in 1979-80 (August-September dischar and low in 1983-1984 ge 1600-1900 cfs) (August-September dischar ge 3000-4200 cfs). A regression analysis of catch data on mean August and September station) discharges (Jensen IISGS demonstrated a high negative correlation (ra -0.89 abundance of youn ,.F=0.05) between g Colorado squawfish and flows. In addition, we reported similiar relationship between a growth of the larvae and mean monthl (r=-0.87, p=0.05). Flows y discharge of the Green River in Late summer are historically and predictably Iow. Field observations during eri that the low abundance and slow the p od 1979-1984 suggested growth of larval Colorado squawfish was an abnormally high suer flow -due to (releases of water stored in Flaming Gorge Dam during flood years of 1983 and 1984) that inundated prime nursery habitat (backwaters) for the species (Archer et al. 1986 hYPothesis was ~ Jones and Tyus 19$5). This supported by research conducted b which aerial y BR in 1987 and 1988, in photography taken at different water levels indicated t availability of backwater hat the habitat was negatively correlated (r=-O.gI~p~0.05) with late summer flows: more specifically, area of back maximized at 1687 cfs water habitat as (average of Jensen, Ouray, and Sand Wash study areas and the number of backwater habitats was ) maximized at 1381 cfs (Pucherelli et 23
