<br />1996, from 3 miles upstream from the diversion to 1.5 miles downstream from <br />the diversion. Fish caught during this trip were marked as described above. <br />On September 16, UDWR completed a sampling trip to look for marked fish. No <br />marked fish were found to move upstream or downstream past the Tusher <br />Diversion, but this was likely due to the limited sampling completed. <br />Information from the three electrofishing surveys is presented in Table 1. <br /> <br />Table 1. <br /> <br />Adult fish collected on the Green River upstream, downstream and <br />at the Tusher diversion plunge pool; 1995 and 1996. <br /> <br />6/95 CS FM BH WE CP CC CH GS BCR <br />upstream 4 42 2 <br />@ TO 3 <br />Downstrea 9 20 3 2 <br />m <br />8/96 CS FM BH WE CP CC CH GS BCR <br />Upstream 1 7 3 15 10 <br />@ TO 5 1 6 1 20 <br />Downstrea 1 4 4 6 17 <br />m <br />9/96 CS FM BH WE CP CC CH GS BCR <br />upstream 2 13 1 14 3 1 . <br />@ TO 4 6 6 9 20 <br />Downstrea 1 7 1 1 11 21 2 2 <br />m <br /> <br />To assess the drift of larval fish through the diversion canal into the power <br />facilities and the irrigated fields, UDWR began setting larval drift nets in <br />the canal on July 13, 1996 and in the main channel downstream from the <br />diversion beginning on July 24, 1996. Sampling continued through:-August 23, <br />1996. One net was set in the canal and two in the main channel for 1 to 2 <br />hours at 0630 daily. Also, three nets were set daily at 0600 at a site 7 <br />miles upstream as part of the final year of the 5-year Flaming Gorge study. <br /> <br />Few fish of any species were collected from the drift nets. Out of 42 <br />sampling days, no fish were collected on 23 days. There were no endangered <br />fish collected in the drift nets set in the canal or main channel downstream <br />from the diversion. However, some "native sucker larvae and speckled dace were <br />collected in the canal and main channel. The following larval fish were <br />caught: within the canal - 52 red shiner, 7 suckers, 6 speckled dace, and 1 <br />channel catfish and within the main channel - 24 red shiner, 3 suckers, 5 <br />speckled dace, and 1 channel catfish. The Flaming Gorge data is not yet <br />available. Timing the drifting larvae and greater intensity may have produced <br />more larval fish. <br /> <br />As part of the UDWR's involvement in the Basinwide monitoring program for <br />razorback suckers, flooded tributary mouths were sampled with light traps <br />during the months of May and June 1996. At the "near Green River, UT" site we <br />sampled habitats which bracketed Tusher Diversion. Those. weekly samples which <br />have not been fully analyzed may offer an additional piece of information in <br />determining if larval fish are entrained in the Tusher Wash Diversion Canal. <br /> <br />Tusher 2 <br />
