The signals from five radio-tagged Colorado pdceminnow that entered the Government Highline Canal during 2001 were all detected at the canal tracking station west of Cameo. One fish was diverted via a siphon into the OMID Power Canal system The other four fish continued further down-canal and did not move into the ONIID Power Canal system. Three of these signals were detected 37.4 miles down-canal on 31 July 2001 immediately up-canal from the automated trash rack. Two of the signals (Codes 153 and 137) were very strong and it was determined that the radio transmitters were on dry land and in a large debris pile on the north side of the canal. It was presumed that these two fish had been raked from the trash grates onto the conveyor belt that removes debris from the canal and deposits it on the north side of the canal. It is unknown whether these two fish were dead at the time they were removed from the canal. Another fish (Code 78) was located about 0.2 mile up-canal from the trash rack on~ 31 July. In mid-August this fish was located further up-canal about 0.3 mile, proving that it was still alive. It is assumed that all three fish were alive when they entered the canal at the diversion dam and passed the canal tracking station west of Cameo. Codes 78 and 137 were detected at the canal tracking station on 11 July abe 26 July each for about 10 minutes. Code 153 was detected on 5 July for over 14 hours at the canal tracking station. Codes 78, 137, and 153 had spent 23, 30, and 50 days, respectively, upstream fibm the diversion dam following stocking before being detected at the canal tracking station. The signals from all three transmitters were very strong when they were detected on 5 December 2(101 in the vicinity of the trash rack at 17-3/4 Road, some 37.4 miles from where they entered the canal at the diversion dam. By triangulation, the location for one transmitter (Code 78) was determined to be in the sedimentation basin immediately up-canal from the trash rack on this date. None of these three radio transmitters were physically recovered. The fate of the fourth Colorado pdceminnow (Code 144) was not determined until eazly- January 2002. This fish had entered the Government Highline Canal and was detected for 4 hours on 11 August at the canal tracking station. Following stocking, it had resided 82 days upstream from the Government Highline Dam before being detected at the canal tracking station. Its signal was never contacted again. However, the radio-tag was recovered and returned by a private citizen on 2 January 2002. The radio transmitter was found in a wetland near a residential area neaz 26-1/2 and G Roads north of Grand Junction during mid-December 2001. Appazently, this fish had traveled down-canal and entered a small irrigation ditch through a head gate 19.7 miles down-canal from the diversion dam. This researcher followed the irrigation ditch from the canal which branched several times-one of the branches eventually terminated at the wetland. It is assumed that this fish entered this irrigation ditch and could not locate its way bank into the canal. The private citizen reported that she did not see the carcass of a fish in the immediate vicinity 28
