liter per minute. The fish were transported from Ouray NWR to Red Wash boat ramp, river mile index (RMI) 298.0 on the Green River. The ramp is approximately 6 miles south of Hwy. 40, off Hwy. 264, east of the town of Jensen, Utah. The fish were removed from the transport tank, via 5 gal. bucket, into two 80 quart plastic ice chests. These ice chests, which were setup on the floor of a 16 ft. john boat, were filled up 3/4 of the way with water from the river. The fish were tempered by filling up the 5 gal. bucket halfway with river water, and halfway with transport tank water. The fish were allowed to sit for 5 minutes in the bucket prior to being released into the ice chests. The fish were then transported to the individual stocking sites by boat. Stocking Sites The stocking sites were preselected from a backwater sampling trip 3 weeks prior to the initial release into the river (8 Sept. 88). The sites were chosen for their ease of both vehicle and boat accessibility, numbers of backwaters in the vicinity, depth, size, and close proximity to a known razorback spawning area. The sites originally chosen were backwater habitats at the following Green River locations: RMI 296.0, RNLI 297.0, RNLI 297.5, and RNII 297.8. The backwater at RM1 296.0 was aborted due to difficulty in initially finding it, and a backwater at RMI 295.5 was substituted in its place. After initial release of fish into RNII 295.5, it was discontinued as a stocking site due to the difficulty in traversing the numerous sandbars in its location. All subsequent stockings occurred only at RMI 297.0, RMI 297.5, and RNLI 297.8. Prior to the initial release of fish on September 8, 1988, both physical and biological measurements were taken at all sites. These included depths, widths, lengths, substrates, turbidity, (Table 1) and fish species present (Table 2). max. avg. avg. depth depth length width area substrate turbidity (ft.) (ft.)
