In addition to the above archival reports prepared by Recovery Program participants, tagging lists of endangered fishes captured by the Colorado River Fishes Project, Colorado River Fishes Monitoring Project, Interagency Standardized Monitoring Program (ISMP), and other state, federal, and private agencies from 1978 to 1997 were obtained from the USFWS to determine most recent distribution trends for larger fish specimens. This information is presented with some reservation, because sampling varies among reach with respect to methods, including different gear, effort, and locations. Some rivers were sampled each year since 1978 and some have only been sampled for a year or two. Nevertheless, in absence of a recent systematic program 6
