was 489 mm TL and weighed 836 g (Table 2). It was PIT-tagged and translocated to the Green <br />River. Other fish found in the raceway included channel catfish, bluehead sucker (Catostomus <br />discobolus) , flannelmouth sucker, and a roundtail chub (Gila robusta) (Table 1). No <br />endangered fish were located between the canal gate and the first siphon, but carp, channel <br />catfish, flannelmouth sucker, and bluehead sucker were captured in this section (Table 1). Joe <br />Hanson (GRCC, personal communication) reported the discharge of the Green River Canal was <br />60 ft3/s (1.70 m3/s) during sampling. <br />Presence of Fish during and after the drainage of the Green River Canal <br />No endangered fish were collected or seen when the canal between the second siphon and the <br />canal gate was electrofished during the initial phase of draining on 14 November 2000. Water <br />depth was approximately two feet (0.6 m). Electrofishing effort was concentrated in this section <br />because Colorado pikeminnow were found here in July 2000. In addition, no endangered fish <br />were observed or collected at the sluice gate during the final stages of draining. <br />Once the canal had completely drained, two days of visual observations found no threatened and <br />endangered fishes. Several isolated pools were seined. Fishes collected in these pools were red <br />shiner, carp, flannelmouth sucker, fathead minnow, channel catfish, green sunfish (Lepomis <br />cyanellus), and bluehead sucker. <br />DISCUSSION <br />The effects of the Tusher Wash Diversion Dam on entrainment of larval endangered fish, while <br />likely, remains largely unknown. Our sampling consisted of only one night in mid-June, which <br />is a little late to catch razorback sucker but about right for Colorado pikeminnow. No Colorado
